Are many kinds of plastic, so far put into production in the world there are about more than 300 kinds of plastic. Classification of plastic are more commonly used in two ways:
1, according to the different nature of plastic after heating divided into thermoplastic and thermoset plastics
        The molecular structure of thermoplastics are linear structure, soften or melt when heated, plastic made of a certain shape, cooling after hardening. In the heat again to a certain degree of softening, cooling after hardening, this process can be repeated several times. Such as PVC, polyethylene, polystyrene and so on. Thermoplastic molding process is relatively simple to continuous production, and has very high mechanical strength, it has developed rapidly.
        The molecular structure of thermosetting plastic body structure, occurs when the heat softening of a certain shape can be made of plastic, but to a certain degree of heat or by adding a small amount of curing agent, after the hardening of stereotypes, and then change the heating does not become soft the shape of the. Thermoset Plastic molding, the heat will not soften, it can not be recycled, such as phenolics, amino plastics, epoxy resin plastics and so on belong to this category. Thermosetting plastics molding process is relatively complicated, so continuous production of certain difficulties, but the heat is good, not easy to deformation, but also relatively inexpensive.
2, according to the use of plastic divided into general-purpose plastics and engineering plastics
        GE Plastics is the large output, low price and wide application of plastics, mainly including polyolefins, PVC, polystyrene, phenolics, and amino-five varieties of plastics. People’s daily lives are used in many of the products made by GE Plastics.
       Engineering plastics are available as engineering structural materials and parts to replace metal fabrication machinery such as plastic. For example, polyamide, polycarbonate, polyoxymethylene, ABS resin, PTFE, polyester, polysulfone, polyimide, etc.. Engineering Plastics has a low density, high chemical stability, good mechanical properties, electrical insulation is superior, easy molding processing characteristics, are widely used in automobile, electrical appliances, chemicals, machinery, apparatus, instruments and other industries, also used in Astronauts, rocket , missiles and so on.

With the restructuring of the food industry, food manufacturers the urgent need for a variety of packaging machinery

1, packaging machine. Automatically measuring, bag making, filling, sealing, printing batch number, cutting and counting, and all other work; automated particle type, fluid and semi-liquid, powder type, film type, and capsule type packaging. There are bulk packaging pillow packaging machine, which is against the solids of the Pillow packaging design, suitable for packaging various types of solid rules-based objects such as food biscuits, bread, moon cake, candy and so on. For the bulk separation of tilting or the individual objects, package material shall be placed in the first box, or the tying swept up in a one, so that the formation of a whole only after the packaging on this machine.

2, filling machine. For mineral water, beer, milk and other beverage packaging liquid filling machine and sesame, fermented flour paste, tomato sauce, butter and other materials, filling paste filling machine groups.

3, sealing machine. This is mainly aimed at packaged food products. Sealing machine is filling a packaging container sealing machinery, in the product into containers, and in order to enable products to be kept under seal to maintain product quality and avoid product loss, the need for sealing packaging containers, which are sealing machine completed.

4, shrink machine. Shrink packaging is currently on the market, one of the more advanced packaging methods, which is the use of shrink film wrapped in the outside of the product or packaging, and heat, so that packing material shrinkage during cooling and thus bind tightly the product or packaging, fully shows the appearance of objects, improve product exhibitions, so as to increase the sense of beauty and value, while, through the shrinking machine packaged items can be sealed, moisture, pollution prevention, and to protect the goods from external shocks, has a certain buffer capacity, especially when used glassware packaging, to prevent broken glass container when flying, in addition, can reduce the product are demolished, the possibility of theft, shrink film shrink machine shrink by generated when a certain tension,, they can be to a group of items to be packaged bind tightly played rope a binding role, especially for more than a collection of articles and tray packaging. Therefore, this product can be widely used in a variety of commodity packaging.

In addition, as people’s awareness of environmental protection and social progress, food vendors are increasingly focusing on quality and stability, lower-cost packaging equipment, packaging machinery manufacturers also gradually machinery are small, flexible, multi-purpose, high-efficiency direction. This trend also includes saving time, reducing costs, by pursuit of a modularized, simple, then it can move packaging machinery.

The 21st century is the century environmental protection, environmental issues become increasingly important as more strained resources and energy to build a recycling economy and society, take the road of sustainable development has become the focus of global concern, and urgent tasks, and become a business strategy and human activities criteria. In order to meet the new demands of the times, plastic packaging materials In addition to asking the market to meet the quality and quantity of packaging such as the increasing requirements, its development must be to save resources, energy saving, easy to be recycled after use, easy to dispose of the environment or vulnerable consumers na or degradation as a technology development point of departure. China’s plastics industry has entered into energy-saving environmental protection era, plastic packaging, new materials, new techniques, new technologies and new products are emerging, and being high-performance, multi-function, actively adopt new materials, new technologies and broaden the application areas, as well as plastic packaging and coordinated development of environmentally friendly direction.

The development of recycling economy is the construction of a resource-saving and environment-friendly society and an important way to achieve sustainable development. Has insisted on developing equal emphasis on conservation, conservation priority, according to reduction, re-use, resource-oriented principle, vigorously promote energy-saving and land and materials to strengthen the comprehensive utilization of resources, improve the utilization of renewable resource recycling system, and the full implementation of clean production, the formation of low-input , low-cost, low emissions and high efficiency of conservation-oriented growth. Actively develop and promote resource conservation, substitution and recycling technologies, accelerate the pace of energy saving technological transformation of the high rate of consumption, heavy pollution and technological backwardness of the process and product implementation of the mandatory phase-out system with a price conducive to resource saving and fiscal policy.

Impedance permeability plastic packaging materials, as can be given good quality, freshness, flavor and extend shelf-life insurance functions by the rapid development and wide application, in addition to the widely used polyvinylidene chloride (PVDC), ethylene vinyl alcohol copolymer (EVOH), the recent years, the development of environmentally appropriate materials, promoting polyvinyl alcohol (PVA), polyethylene terephthalate (PEN), a total of polyamide (MXD6), silicon or aluminum oxide steam film (soft glass), nano-inorganic materials, such as the development of more compelling.

Functional packaging materials, such as functional preservation of film, sheet, microporous breathable film preservation, choose to packaging films, multi-functional heat shrinkable packaging film, as well as a special function, convenience (easy to Kaifeng, easy to re-seal) packaging materials and products, etc. will be even greater development. Aseptic packaging materials and technology The biggest advantage is the sterile conditions, without preservatives, no refrigeration, it can maximally retain the original nutrients of food and flavor, can significantly extend shelf life, convenient storage and transport, market development very quickly, use expanded, in addition to the dairy, fruit Khan, accounting for a larger share of the beverage, the will be further extended to pharmaceuticals, cosmetics and condiment areas.

Nano-composite packaging materials will be with the rapid development of nano-technology and rapid industrialization, due to its wear resistance, hardness, strength, resistance permeability, plasticity were significantly enhanced and improved, except for food packaging can be used for special packaging such as anti-static, anti-electromagnetic, explosion-proof and invisible, dangerous goods, packaging, etc. It is expected to promote the traditional plastic packaging materials, a huge change.

Environmentally friendly (environmental fitness) plastic packaging materials (or green plastic packaging materials), with the series of environmental management standards ISl4000 the implementation of a global hot spot of concern, including easy recycling of plastic packaging materials such as PET, PEN, easy to environmental degradation plastics (EDP) in the bio-degradable plastics, have become hot in the hot, others, such as zero pollution foam, thin-walled bottles and biodegradable material is also cause for concern.

Heat canned plastic bottles of juice and tea drinks packaging, with the traditional sterile paper packaging, three-piece metal cans, glass bottles has more ability to lower costs, material and transparent, light weight, easy to damage, environmental protection and good adaptability advantages, it has been more and more widely used, use of accounts for the entire city of more than half of canned heat. In addition to heat canned PET plastic bottles, the bottles are subject to greater attention in recent years, BOPP. BOPP bottle has the following advantages: the improvement of heat resistance, stretching through the PP process, canned temperature can be increased to 100 degrees Celsius, does not require special equipment, bottle handling, and to greatly improve the oxygen barrier: BOPP bottle does not absorb moisture, longer term storage, easy recovery: PET bottle production costs lower than 20%.

Symbian system after seven years of development, users in late 2006 had been successfully break 100 million. Can achieve such a feat, and is responsible for core research and development Sybian Nokia, the Finnish giant has a close relationship.

Packaging technology is an important symbol of modern civilization, while the packaging machinery to achieve the material guarantee of modern civilization. Packaging machinery and the close relationship between national economic development. The higher the level of national economic development, the higher the requirements of the packaging require the development of high speed packaging machinery, technology high level of species diversity, product quality is stable.

China’s packaging machinery industry in 2008 is still in good growth in the state: production and sales rise, profit growth rapidly increased exports in the machinery industry, outstanding performance in a “bright spots” in the industry. 2008 packaging machinery industry-wide main business income of 13.18 billion yuan, up 10.9% year on year in 2007; of these, major packaging machinery industry as the main revenue growth 24.39% compared to 31.70 percent during the same period in 2007 decreased by 7.31 percentage points, to become Machinery industry profits, one of the fastest growing industries.

Founding 60 years ago, our people’s living standards and people’s income has undergone tremendous changes in packaging machinery thus widely used in food, pharmaceutical, chemical and other various industries.

Food and other light industrial products only from the point of view, in China’s total exports account for 1 / 3 or more, are required to improve packaging grades, which for the development of packaging machinery has brought many opportunities, food packaging needs of a wide range of packaging machinery With the continuous improvement of people’s living standard, people’s consumption patterns from subsistence-based to enjoy the change, so packaging machinery industry is a sunrise industry.

Comprehensive upgrading of packaging machinery and equipment in China and the world packaging machinery development trend.

Chinese version of the whole machine market, but also for the aircraft hit a shot in the arm, cost-effective is more prominent. Now prices have fallen the aircraft a very attractive range, like a friend Think about that.

1, terrible fire

For many years, people think that PVC is the harmony of nature, a man-made note that it is destroying the environment is not conducive to eco-development. Dusseldorf airport in 1996, a sensation, so that 17 people were killed in the fire, a number of errors of public opinion has helped people to PVC as the main culprit of this fire, it will increase the people’s misunderstanding of PVC .

2, the beautiful appearance

The surface and shape of the goods will leave a first impression. Advertising psychologists believe that this first impression of the sale of the product plays a decisive role. In this sense, layer, PVC film is very promising market prospects. In fact, with the development of the times, PVC is also its good performance, simple process, as well as many other advantages of gradually won the hearts and minds of the people has been more and more people accepted and recognized in the United States and Europe is a PVC the darling of the construction industry, PVC in people’s daily life everywhere. PVC can be expressed in not only the color of nature, but also can show the color of people’s fantasy. In Germany, 40% of the furniture is to use PVC to make the surface of the material, see the natural color and luster, the color gorgeous, rich and varied, design beautiful, elegant style and high-end desk, shelves, sofas, kitchen cabinet, and no one will take them and the streets are devastated “white trash” to associate together, would not think it is PVC blister film give them such a beautiful coat.

3, the structure of perfect

So what is it PVC in the end? PVC, full name Polyvinylchlorid, the main ingredients of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility and so on. This surface film of the top are painted in the middle of the main component is PVC, the bottom is coated adhesive back. It is loved the world today, is quite popular and also widely used as a synthetic material. Its global use of synthetic materials in a variety of the second highest. According to statistics, only one year in 1995, non-PVC production capacity in Europe, there are about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption of an average of 1.4 million tons. PVC is the growth rate of 4% in the world within the scope and application. In recent years, the growth of PVC in Southeast Asia is particularly significant on several occasions, thanks to the Southeast Asian countries have carried out the urgent needs of infrastructure construction. Before you can produce three-dimensional surface film of the material, PVC is the most suitable material.

PVC can be divided into soft PVC and rigid PVC. Hard PVC market in which about 2 / 3, soft PVC and 1 / 3. Soft PVC are generally used for flooring, ceilings, and the surface of leather, but because of soft PVC containing softener (which is soft PVC and rigid PVC distinction), easy to become brittle and difficult to preserve, so its use has been limited. Hard PVC free softener, so flexibility is good, easy molding, easy crisp, non-toxic pollution, save a long time, so the development has great application value. The following are referred to as PVC. PVC is essentially a vacuum blister film for packaging various types of panel surface, it is also known as decorative films, with a film applied to building materials, packaging, pharmaceutical and many other industries. Building materials industry, which accounts for the largest proportion, 60%, followed by the packaging industry, there are a number of other small-scale applications industry.

4, rigorous process

The reason can be widely used in PVC building material industry, there are two very important reasons:

First, the unique properties of PVC (rain, fire-resistant, anti-static, easy to shape), the second is a PVC low-input high-yield characteristics. So, PVC is able to do with these two major distinctions? Let us find the answers from their manufacturing process up bar.

PVC production process is not complicated, general production line generally rolling machines, printing presses, coating machines and cutting machines back composed mainly through direct-acting rolling machine mixing, roller-rotation and high-temperature rolling to produce thick of 0.3 mm to 0.7mm film, the production at the same time and through the printing press in the membrane color printed on the front, through the back coating machine in the membrane attached to the back back coating layer. Must not underestimate this layer back coating, which is the performance of PVC membrane is an important guarantee of quality. Back painted by special material composition, is a high-energy pro-and liquid, it is precisely because this layer back coating, PVC film can be tightly and medium density board or other boards together, decades, or even fifteen years not open plastic. Ordinary paste mask can not be solved at the biggest problem is the issue of membrane shedding. As the entire production process is at a high temperature (rolling machines, the temperature reaches 220 degrees) carried out, which makes PVC film with high resistance to light and fire resistance to ensure high-quality PVC film. Of course, this very demanding on the production machine, usually a set of production line equipment cost about three thousand nine one million marks, equivalent to approximately RMB 160 million yuan. On the other hand, PVC film production process is quite simple, machine production is also big, so a comprehensive look, PVC is actually a low-input, high-volume products.

5, exceptional performance

PVC film with ordinary paste film, what different? Ordinary paste film is at room temperature, the direct use of glue attached to the plate surface, so after one or two years after the foil is easy to fall off. The PVC membrane is the application-specific vacuum lamination machine in 110-degree high temperature pressure plate attached to the surface, so easy to fall off.

Although the PVC film has excellent quality assurance, but some people may say, PVC, after all, chemical products, it is not as natural materials, can not be ruled out toxicity and odor, they will inevitably harm the environment. This is not true, it is because Germany is the raw materials for production of PVC membrane through a special extraction, toxic substances have been completely extracted, so PVC is completely non-toxic and tasteless, to human skin or respiratory system without any stimulation, for those who wood and paint people who are allergic to the use of PVC film packaging of furniture or kitchen is very appropriate. Through the use of PVC film for decorative film, people can use in a large number of secret board, particleboard, plywood and fiberboard to reduce the use of timber volume, thereby reducing the forest as well as environmental damage. From this perspective, PVC film for protecting the ecological environment has made a significant contribution.

The use of PVC in Western countries once caused a great controversy, many people tried all kinds of other materials to replace PVC. But the fact is, PVC mass ratio compared favorably with other alternatives, while the cost is cheaper than these materials. Experts through research found that in many industries, abandon the use of PVC will have a significant number of additional costs. Specific data indicate that abandon the use of PVC will be increased by several billion marks extra cost. With regard to specific consumers, this will mean a significant additional expenditure. With the surface material with PVC windows, for example, if these windows do not use PVC, but use ordinary wood as the surface, it is only necessary to increase the cleaning and maintenance of a number of extraordinary expenses. A small town in the UK, people in the past two decades, used wood windows, some of these windows, cleaning maintenance costs of the investigation and with the costs of cleaning PVC window to compare the results show that wood system of ordinary window clean-up costs of the clean-up costs than the PVC window twice.

6, a bright future

PVC industry is currently the world’s rapid development and broad prospects, all countries are optimistic about the potential of PVC, as well as its ecological benefits, PVC is its superior and unique performance to the world to prove their role and status of the current can not be replaced by any other product , social development needs of its environmental protection need it, and it is our human society, civilization and progress of the inevitable trend.

Note:

Germany is a PVC product showcase country, its production process has a long history, experienced, a world leader in terms of alone cabinets, PVC materials, accounts for 75% of the market share. Germany RENOLIT (Renolit) Corporation is the world’s largest PVC manufacturers. RENOLIT (Renolit) group belongs to RENOLIT – Wilk Limited have 16 production bases throughout the world, more than 2,000 employees. Its production of PVC film, with its excellent quality and international reputation. Shanghai Trading Company is a RENOLIT Germany silicon (Renolit)’s Greater China general agent, solely responsible for RENOLIT (Renolit) company in the Greater China region for all sales operations. Unite the entire company from top to bottom, work together to pursue client interests above everything else the strict purpose, warm and thoughtful and dedicated service for every customer.

As the world when the PVC industry flourishing, but unfortunately, in our domestic PVC furniture materials (including cabinet) market share of less than 10%, many consumers have not even heard of PVC as a furniture material, but I do not know PVC are. Why did Germany, as a higher-grade PVC film, non-toxic non-polluting (not including heavy metals, materials), environmental materials, the domestic market share is still so limited? Here, of course, there is a consumer-level problems, but mostly with our consumers pairs of PVC lack of proper understanding of this material relevant. It allows the production of PVC membrane of furniture has been limited, and thus can not scale. I believe that through the joint efforts of our peers, the market matures, PVC industry in the field of furniture, some at a new level.

It is predicted that by 2013 U.S. demand for green plastic packaging will grow 3.4%. Statistics informed that the fastest growth is taking place is a bio-degradable plastic packaging and recyclable plastic packaging.

Bio-degradable plastic packaging is expected to rise in 2013 annual growth rate of nearly 13%, will promote the traditional bio-degradable plastic resin price competitiveness increased, the rapid expansion of production capacity, and reduce the price volatility of biodegradable plastics and petroleum-based plastic packaging materials.

In the recyclable plastic packaging and is expected to increase the overall average growth rate of joint green plastic packaging around the 3.3% annual growth rate, strong growth for the recycled plastic, plastic packaging content for more funding to work together to enhance the cycle collect the amount of recycled content. Reusable plastic packaging number predicted to be more slowly, 2.7% per year.

This year’s two sessions have been concluded, however, impressive in a word “carbon” in particular keep people’s minds. “Low-carbon economy” for the first time among the two sessions, one of the hottest in the Internet survey, the “low carbon” word into two sessions this year is an important keywords. The deputies and members are generally concerned about the low-carbon issues; Jiu San Society “submitted on promoting low carbon economic development of China’s proposal” by the attention of all sectors … …

At present, the food industry rejects the excessive packaging, refuse to squander phenomenon. The use of recycled materials or sustainable production of forest products that do the voice is also growing, in addition to industry sources, the community called for environmental protection, low-carbon packaging voice getting higher and higher. Main reasons for this phenomenon, I think that apart from raising the level beyond which people understand, but also with the “excessive packaging” the impact of a certain relationship.

Excessive packaging has become a public nuisance

Over-packaging of goods has become a major hazard in today’s society, which not only caused economic loss to society, but also brought some social problems.

Excessive packaging not only created a huge amount of domestic waste, but also contributed to commercial fraud wind, damage the interests of consumers.

Statistics show that a number of luxury goods packaging costs have accounted for 70% of total product is already overwhelming and even black-hearted businesses the opportunity to bundle other products, consumers money and cost of an ordinary or even inferior goods purchased.

In addition, excessive packaging is also induced by the social atmosphere of a luxury, hidden corruption, exacerbated social disharmony. Astronomical moon cake, sky-high price of wine, astronomical health care products and so on, the wind-induced social luxury; excessive packaging holiday gifts by some as a “fig leaf”, with a valuable securities, gifts and even money, open bribery of the Road.

The impact of over-packaging is not only our daily lives, while those who are still a waste of our human finite source of energy. Refuse excessive packaging, promoting environmental protection, low-carbon packaging will be the general trend. Food packaging before the food distribution market, an essential process, access to relevant information, the author found that low-carbon technology can affect the food packaging a number of factors, but mainly packaging materials and packaging design of the two major factors.

Packaging materials have been made towards the development of low-carbon direction

1. Repeated reuse and recycling of packaging materials

Repeated re-use packaging, such as beer, beverages, soy sauce, vinegar glass bottle packaging with repeated use. Sweden and other countries to implement PC PET PET beverage bottles and bottles of re-using up to 20 times or more. Netherlands Wellman Inc. Johnson Inc. and the United States carried out 100% of the PET container recycling.

Packaging materials reuse and recycling, just to extend the plastic packaging materials such as polymer materials as life, when reached its useful life, they still faced with the treatment of waste and environmental pollution problems.

2. Edible packaging materials

For decades, people familiar with the use of sticky candy packaging paper and packaging ice cream corn baking cups are typically packaged edible packaging.

Is now generally used in edible plastic wrap, has developed into a multi-functional in nature, by a variety of biological macromolecules (proteins and polysaccharide) and lipid membrane made of multi-component food. Such composite membranes mainly through the interaction between different molecules, the formation of a stable emulsion, and then dried so that solvent evaporation and the formation of porous, transparent or translucent three-dimensional network structure of the film, the porous network structure so that with a clear waterproof film and a certain degree of choice permeability, and thus in the food industry, particularly in fresh fruits and vegetables, the broad application prospects.

3. Biodegradable materials

Biodegradable materials refers to the performance loss caused by a specific time within a particular environment, its chemical structure changes as a plastic.

Biodegradable plastic packaging material has both the functions and features of traditional plastics, but also the completion of life, adopted the role of ultraviolet sunlight or soil and water microbial role in the degradation and restore the natural environment division, which will eventually non-toxic the form of re-entry into the ecological environment, the return to nature.

According to reports, a new type of environmentally-friendly food packaging materials is expected to come out recently in the United States. Successful development of this new new food packaging film can prevent the infiltration of oxygen to achieve the preservation effect. Because of this new material from the composition of the main stem not suitable for eating vegetables and fruits, so it can be an biodegradable, environmentally friendly material. Estimated that this new material in the future is likely to replace traditional plastic film of polyethylene food packaging industry to become the main material.

Packaging design should also be a low-carbon

In the packaging field, product packaging shape is equally important, therefore, designers are making packaging design when, in addition to the pursuit of innovation, should also strive to convey the product’s brand identity and personality.

Taking into account the environmental requirements of consumers, the product’s overall weight and packaging materials is also very important to two factors. The targeted design strategy can quality into products, thereby enhancing the enterprise price points and profit margins, reduce material waste. Such as the U.S. market, a common cube wine is a good example, it can make the product a unique appearance in many competitors.

Carton manufacturer Chesapeake (Chesapeake) the company’s marketing director Bob Houghton believes that good design and reasonable structure is not only can reduce packaging waste, but also in some cases, to reduce plastic use.

Environmentally friendly packaging materials, coupled with a targeted design, is bound to reduce the material waste, the corresponding also reduced the production costs and increase profits, but the significance of low-carbon far more than this, the better to reduce the carbon emissions, protecting our environment for survival, creating a good living environment.

Whether the Copenhagen meeting, or two sessions of “low carbon” hot discussion, there are indications that low-carbon way to explore is the trend of social development and people’s consensus. Any one country’s sustainable development is indispensable to the effective and rational utilization of resources, China’s rapid economic development in recent decades, remarkable achievements, but it is undeniable that our model of economic development was still based on high energy consumption and on the basis of high pollution. In the food industry, environmental protection, low-carbon voice rising, “excessive packaging”, “blind packaging” means packaging such as high-carbon have also been improved, but the face of the existing results we can not relax, we should sort out ideas, to explore better low-carbon packaging, to the development of China’s low-carbon packaging road.

Sharp mobile phone charm is the beauty of women, particularly attractive to the user can imagine, but unfortunately just to enter the mobile phone market in China to provide the near Sharp models are not too many choices, but only in the appearance of which several models there are some differences of detail, mostly identical in function, although this for Sharp to look as a selling point for the mobile phone brand is nothing wrong with this practice, but actually causes the user to be able to choose when you purchase does not more.

Few days ago, and accurate is January 12, 2010, Sharp has released three models in Tokyo, a new stylish clamshell phone, but also based on science and technology as a selling point. SH6220C/SH6228C two models which have “mirror LCD Yi” Material 3-inch super-large external screen, SH6230C is to support “SOLAR HYBRID” solar charging feature. Today, we need to give this description is that “there is sunshine, there is electricity” support for solar charging capabilities Sharp SH6230C.
