The face of the market on a wide selection of drinks and a variety of alcoholic beverages, its packaging to attract people’s attention has become a bright spot, elegant design, chic bottle shape for their elegance. Maybe you never noticed that in fact cap – as packaging in a small link in ensuring product quality and shape the product personality is also essential.

Bottle cap as part of the package, its functions are mainly two things: First, seal, the protective effect of wine, which is the most basic function of cap, but also the manufacturer of the most easy to do; second, aesthetics, As an integral part of the package, small caps can play the role of finishing touch. At present, some manufacturers in the selection caps on the effects of too much emphasis on its security is closely related to their technical content, but not the decisive role of the product itself, but the country’s laws and regulations and consumer self-protection.

In recent years, anti-counterfeit alcohol manufacturers increasingly attention as a bottle cap packaging as part of its anti-counterfeiting features and toward the production of forms of diversity, gentrification development. Is broken, type, open type, be able to sing, speak, multi-security bottle cap has been widely used by manufacturers.

Although the anti-counterfeit bottle features the ever-changing, but its use of materials, there are two main types,, Bp two kinds of aluminum and plastic.

Looking abroad, wine bottle packaging, which is characterized by colorful and has stability. In most cases, aluminum bottle caps, a simple form, making fine group of advanced color printing technology to make it consistent, exquisite design, gives a sense of refined elegance. , Caps style to use more traditional model, less change. Such as the Scotch whiskey bottle, then accompanied by pure black gold writing, gives a quaint, elegant, long-lasting enjoyment of feeling, played its proper role in identification.

The external form of the machine is the mobile phone type, now more commonly used classification is to be divided into a clamshell mobile phone (single screen, dual-screen), upright type, slide, rotary these types.
Clamshell: clamshell-style phone is the phone is folded, to cover before they can turn to see the main display or buttons, and only one screen, then the phone is called a single-screen flip phone. Dual-screen flip phone, that is flip on another sub-displays, the screen is generally small in general can display time, signal, battery, caller ID and other functions.

Upright: Upright mobile phone means phone screen and keypad in the same plane, mobile phones, flip. Vertical is mainly characterized by cell phone can be directly displayed on the screen to see the content.

Slide: slide-type mobile phones mainly refers to the cell phone can be seen through Withdrawing all of the fuselage. Some models is by sliding under the cover to see the keys; while others are part of the screen through the pull-up to see the keyboard. To some extent, slider-style phone is a clamshell mobile phone an extension of and innovation.

Rotary: Rotary phone mainly refers to the roof to see through the spin button. This phone features can be seen directly to the screen, rotating when necessary buttons to open shelters, it is the vertical flip-type mobile phone handset and integration and innovation.

And the vertical clamshell mobile phone comparison
Clamshell phone features:
Appearance of elegance, generosity, and was considered a sign of high-end models
A larger screen, dual screen can display more
Flip phone tend to be more short
Flip phone keypad lock eliminates the work of
Vertical Phone Features:
Appearance of simple, compact
Content can be seen directly on the screen, for example: calls, SMS, etc.
Overall, vertical flip-type mobile phones and mobile phones each have their own advantages, of course, they also each have their own shortcomings, such as: flip-style cell phones used for some time, due to repeatedly turn over cover, the phone itself will cause certain adverse effects, such as loosening of pumping. The vertical cell phone has its own flaws, that is, must always lock the keyboard, otherwise, and easy in the knowledge of the case of outgoing calls; same time, those upright need to unlock the phone after the lock button can be used, to some extent also virtually increase the workload of mobile phone users.
In short, no matter what type of cell phone do not have absolute advantages and disadvantages, with regard to the type of mobile phones more and more choices is determined based on personal hobby.

Photodegradation refers to sunlight, the light absorption of UV radiation degradable plastics induced by light after the role, so that keys can be weakened, long-chain split into fragments of lower molecular weight polymer damage the integrity of the physical performance. Low molecular weight fragments in the air, further oxidation occurs, resulting in free radical chain scission reaction, can be degraded into low molecular weight compounds of biological decomposition of the final was completely oxidized to C02 and H20. Throughout the degradation process is initiated by photo-degradation and oxidation of free radical chain-breaking combination of Norrish reaction.

Photo-degradation factors

Impact plastic optical degradation of the main factors include:

1. Plastic molecular structure. Light degradable plastics is the photodegradation of the molecular structure of the main factors.

2. Photosensitizer. Add a photosensitizer can promote the photodegradation. Photosensitizer that can be sustained at the initial stage of its photochemical reaction. The induction period, was light-induced excited-state energy can be transferred to the polymer (plastic), to accelerate its photochemical reaction, so that the degradation and oxidation of plastics. Commonly used photosensitizer with acetylacetone metal compounds, dithiocarbamate metal compounds, ferrocene, stearic acid salts and fatty salt.

3. Optical wavelength. According to quantum theory of light, the shorter the wavelength, the light quantum has the energy of the larger, in the range of 290μm ~ 400μm by UV light energy is generally higher than with the plastic polymer chain caused by a variety of energy needed to break chemical bonds. However, a variety of polymer structure on the sensitivity of different wavelength. If the wavelength is not absorbed by a polymer sensitive to the wavelength, its photodegradation very small. Therefore, the UV wavelengths to be sensitive to fracture and plastic polymer to match the wavelength.

4. Atmospheric conditions. The atmosphere of oxygen, heat and humidity will accelerate photodegradation. If the increase of temperature, thermal motion of polymer increased, increased number of collisions between molecules are conducive to contact with oxygen photo-oxidation.

Over half a century, plastics rapid development of industrial technology, its use has infiltrated into the industrial, agriculture and people’s lives in various fields, and with steel, lumber, cement, tied for the four pillars of the national economy materials. However, the use of plastics is followed will bring a lot of solid waste, especially plastics, such as food packaging bags, beverage bottles, such as the extensive use of agricultural films, serious pollution of the human living environment has become a worldwide public hazard. Data show that municipal solid waste in the quality of the percentage of plastic has reached over 10%, volume percentage is 30%, while most of which are daily disposable plastic packaging and waste, their impact on the environment, the ecological balance of damage has caused great concern in society. Thus, the solution to this problem has become imperative to protect the environment.

In general, the plastic apart from other thermal degradation, light degradation in the natural environment and bio-degradation rate than the slower, with Cl4 isotope trace plastics in soil degradation, results show that the degradation rate of plastic with the environmental conditions (rainfall volume, permeability, temperature, etc.) vary, but overall, the degradation rate is very slow, generally believe that 200 years ~ 400 years. To solve this problem, industry has been introduced in developed countries burial, incineration and recycling methods such as disposal of waste plastic, but there are several ways this can be overcome deficiencies. Processed for landfill covers an area of more instability and makes the landfills. When it comes to incineration, the issue of heat because of their large, easy to damage burning furnace, and the discharge of dioxin, and sometimes might also emit other harmful gases. As for recycling, it is often difficult to collect or even forced to collect for recycling, economic efficiency is poor or even no cost. Thus an increasing number of scholars to promote the development and application of degradable plastics, and will address it as an ideal way of the world problems. At present, the world’s developed countries to actively develop degradable plastics, the United States, Japan, Germany and other developed countries have drawn up to limit or ban non-degradable plastics regulations.
Degradable plastics

Degradable plastics is a kind of the performance of their products to meet the use requirements, while preserving the same period of performance, but under the conditions in their natural environment after use, can degrade into environmentally harmless substances of plastic. According to their degradation mechanism of degradable plastics into bio-degradable plastic, the light degradation of plastics and degradable plastics. The 21st century is the era of protection of the Earth’s environment, resource, energy and more intense era for the treatment of those large, decentralized, messy, difficult to collect or India to make mandatory the collection for recycling, economic efficiency is very poor or non-effectiveness of a one-time Plastic waste, not only the ecological environment caused by pollution, but also for resources and a great waste of energy. Degradable plastics can reduce the white pollution, there have been significant economic and social benefits, for efficient research and development of degradable plastics have become the plastics industry, packaging industry and environmental protection as a major development strategy, but also become the world’s attention in research and development of hot spots . At the same time, as people increased awareness of biodegradable material, as well as the continued strengthening of environmental awareness, such materials will have a very broad prospect.

At present, China has become the largest plastic consumer, a huge market demand of plastic raw materials led to a huge gap. Further enhance the processing of waste plastics recycling production of renewable materials, can not only fill about 25% of plastic raw materials shortage, but also effective in reducing environmental pollution and energy consumption of resources. The news was announced by the end of October from Baotou City in Inner Mongolia, the inaugural China Plastics Industry Forum and the 2009 Plastic new technologies, new materials, new results on the exchange of the General Assembly learned information. Experts also pointed out that China’s current development of plastics recycling industry is still there are many bottlenecks, must be taken to break the five measures to enable them to truly embark on the track of scientific development.

According to the China Plastics Processing Industry Association, Liao genuine, China’s recycling of waste plastics over the past 30 years of development, has become a resource-based environmental protection industry, full of potential. At present, waste plastics recycling enterprises have more than 20000, in which small and medium-sized enterprises in the country there are dozens of plastic waste are located in parts of the professional market, which is characterized by intensive processing of transactions, and the supporting process integration, professional fine of clear division of labor. Recycling of waste plastics from production of 20 billion yuan in 2000 to the present 1,000 billion yuan.

China’s waste plastic recycling of domestic and imported sources include two parts. In 2008, the total amount of waste plastics recycling is about more than 1600 million tons, of which domestic recycling capacity of 900 million tons, imports more than 700 million tons. In 2009, the domestic plastics recycling industry, despite the financial crisis, but still achieved an overall growth in the whole year is expected to recycling waste plastics will be larger than 2008 levels.

As the waste plastics recycling industry, mergers and acquisitions, restructuring, mergers, holding and other forms of structural adjustment Damulakai, domestic and foreign industrial capital and financial capital, will compete in China’s vast waste plastics industry. Waste plastics recycling companies will split and strong comprehensive strength of enterprises will grow stronger, some small and medium enterprises will wither away. Waste plastic recycling into high-end products will also be low, the market will be more standardized, large-scale conditions for the development industry as a whole will become increasingly sophisticated.

CPPIA plastics recycling special committees the Secretary-General Ma Zhanfeng analysis showed that currently, the domestic waste plastics recycling industry are seven major bottleneck problems: one is our lack of macro-level of waste plastics recycling industry, the development of integrated planning, lack of waste plastics recycling industry and re-processing enterprises to support specific policies, in particular the lack of plastic source analysis and monitoring, consumers will be the same as low-quality recycled plastic products, misunderstanding, largely restricted waste plastics recycling industry’s healthy development; The second is to the existing waste plastics is specialized in processing, lack of management trading market, resulting in widespread confusion in management, lack of standards for recycled products, lack of technical research and development support, and poor quality of personnel situation, the urgent need for policy guidance and standards; the same industry price cut-throat competition among enterprises intensified, waste plastic processing enterprises in order to obtain raw materials have to increase the purchase price, the profitability of the existing fragile balance can easily be broken, resulting in large losses.

In addition, the domestic waste plastic import market confusion, the risk of foreign waste imports continue to grow. As China’s plastics recycling industry, the rise of unscrupulous foreign businessmen can not be readily processed or can not re-use of waste plastic garbage shoddy or non-normal channels, exports to China, not only seriously polluted the domestic environment but also to domestic plastics recycling industry, caused no small loss. Although the domestic environment continuously strengthen the supervision, but many small-scale waste plastics recycling enterprises are concentrated in rural areas, technical inputs, lack of advanced process equipment, resulting in secondary pollution is widespread, in order to make a profit at the expense of environmental pollution of the phenomenon is difficult to stop. In addition, the amount of waste plastics in China an increasingly large source of waste plastics are still no reliable survey data, as well as guide the development of the industry classification of technical specifications, thus affecting the industry, technological progress and level of treatment improved.

In view of this, the participating experts, nearly 300 scholars and business representatives put forward five measures to crack these problems. One is to increase the added value of waste plastic recycling. At present, many enterprises are still using the traditional techniques of waste plastics recycling, difficult to completely remove all contaminants, resulting in greatly reduced value-added products. The realization of this goal, under the conditions of the existing process is entirely possible. Related enterprises should seek strong technical force with professional bodies, select t profit of 1,000 yuan or more processing projects and the corresponding technical, and only way for companies to withstand market risks. Second is to improve the conditions of process technology. Take the path of large-scale introduction of new process line is the most effective way to reduce costs, but also waste plastics recycling company an important means to achieve competitive advantage. Third, focus on cleaner production. Waste plastics industry should continue to improve the design, improve management, from the source to reduce pollution and improve the comprehensive utilization of resources. The fourth is an extension of the promotion of industrial development. Domestic waste plastic recycling industry chain of points, sorting, cleaning, granulation, or modified, molding, meticulous division of labor, but it is so that each part of the cost of recycling waste plastic overlay makes the final cost of a significant increase in terms of maturity Enterprises can extend the industrial chain from top to bottom, this can be significant cost savings. Fifth, the state economic policies pursued by recycling of waste plastics recycling industry should be inclined to encourage its path toward recycling economy.

Traditional industries, new industries far too cumbersome to survive the difficult

While the industry calls a traditional plastics industries need to be a replacement, but the replacement of degradable plastics businesses and there is no better life. Degradable plastics Professional Committee announced that the Secretary-General Yunxuan recently revealed that China enterprises engaged in production of bio-degradable plastic products of about 100, most of them hovering on the line between life.

According to Yunxuan Xuan introduction, the international community widely expected that a substitute for conventional plastics market demand for degradable plastics will be more than 10% annual growth rate. Last year, in June, China was formally promulgated in the plastic limit is equal to speed up the development of degradable plastics business. However, after the initial joy, order, and not, as of degradable plastics company is willing to keep coming. Yunxuan Xuan told reporters that the domestic annual production capacity to 1 million tons of the company has only 20, the entire industry, only 20% of the enterprises in the profit, most of the other still are in investment stage. Meanwhile, the domestic market environment makes it difficult for biodegradable plastics company. 10 years, initially optimistic about the industry, many companies are supporting not keep close went out of business, but also some companies turn to do in order to survive the oil-based plastics.

It is understood that most of the current domestic market for degradable plastics products overseas, the proportion of above 70%. Biograde (Nanjing) Environmental Material Co., Ltd. Leader Fangxi the view that domestic city

Field is still in cultivation period, the price is the biggest bottleneck. It is understood that, due to the different cost structures, bio-degradable plastics more expensive than ordinary plastic. Therefore, bio-degradable plastics in the domestic market, basically nothing. 8 years ago, the Ningbo Tian An Biological Material Co., Ltd. invested a total of more than 6000 million to develop bio-degradable plastics, but eight years later is not yet profitable business. Xuejun Chen, general manager of the company laments that, insist on an eight-year project has not yet profitable, the difficulty can be imagined.

It is understood that in foreign countries, government policy or taxation through the price adjustment in support of bio-degradable plastics industry, while China’s current policies on bio-degradable plastics industry support for weak, bio-degradable plastics business policies are rarely specific help.

Yunxuan declare that to open the domestic market situation of degradable plastics, one must rely on tax breaks, two special funds to rely on the support of subsidies. Like the new energy industry, like, for degradable plastics industry to really support, not just stop at the macro level. At present the State macro-policy support, but the lack of details. Such as bio-degradable plastics business tax-free to what extent, biological, and plastic products to the price to compete with the cheap plastic, and so there is no argument.

This new packaging product development company spokesman that the water-soluble packaging products will bring about another industry, market opportunities, describe such a diversity and flexibility of biodegradable plastic materials would be extremely welcomed by the modern man. The spokesman said: “Just think, this plastic packaging products can be of any use of biological decomposition of the ink color, pattern printing, but also to meet the demand made of a different size and shape. Not to mention the general retail market, it shipped the army, air , pharmaceutical, automotive and other industries need to use plastic bags. all walks of life can play a creative, arbitrary design distinctive packaging style, breaking the old tradition of enterprise products bring a new look. “

Is a kind of blister packaging technology, use of ultrasound machines produce ultrasound, the bubble shell bubble shell with bonded together to form pairs of blister packaging, and high-frequency sealing the difference is that ultrasound can not only sealed PVC, PETG materials, could seal the PET material, but also for packaging products are not electromagnetic damage, especially for electronic products packaging; lack of edge is that ultrasound can only be a point-like interval, and is generally a time sealed a straight edge.

Weakness in the European market, prompting UPM-Kymmene Group and other European paper makers will be focused on Latin America and the Chinese market, UPM-Kymmene, said Chairman of the Board Bjoern Wahlroos.

“These districts have a new competitive raw materials, as well as the final product demand is rising markets, expansion of the forces in these areas is right,” Wahlroos 4 in Helsinki said in an interview. “Most of the global paper manufacturer in Latin America to expand pulp business expansion in China and India, paper business, because this is where you can play a role.”

UPM-Kymmene in July last year, took over the Uruguay pulp mill and a eucalyptus plantation in order to South American countries to expand production and reduce production capacity in Finland. This transaction will help to UPM-Kymmene paper mill in China to provide low-cost pulp supply. In Latin America, eucalyptus in 7 to 10 years time you can start logging, while the spruce and birch in Finland will have to 60 years. Although the closure of UPM-Kymmene of Finland region can not be any other major paper mills, Wahlroos said he was convinced that UPM will be similar with the plywood business reorganization and other businesses to continue to take effective measures.

UPM-Kymmene plywood sector in January said it would dismiss 830 employees. UPM-Kymmene and Stora Enso are in Finland to reduce their employees and reduce capacity, to cope with falling demand.

Vacuum packaging technology originated in the 20th century, 40 years. Since 1950, polyester, polyethylene plastic film packaging has been successfully applied to the vacuum packaging machine will be a rapid development, its technical development trend is mainly reflected in high productivity, automation, stand-alone multi-function, the composition of production lines, using new technologies related to these 5 categories.

1, high productivity. Vacuum packaging machine’s productivity has developed into several pieces per minute, the number 10, thermoforming – filling – sealing machine productivity up to 500 / min or more.

2, automation. Such as Zhengzhou Spark 500 pairs of chamber vacuum packaging machine with a vacuum, sealing, printing, cooling off the completion of the function, mainly used for tea, peanut, shrimp, corn and other food packaging.

3, stand-alone multi-functional. The stand-alone to achieve multi-functional, can be easily expand the scope of use. Multi-function must be used to achieve stand-alone modular design, through the transformation and combination of function modules, to be applied to different packaging materials, packaging materials, packaging requirements of the different types of vacuum packaging machine. Representative products are owned by BOSCH Germany HESSER plant in spindle wheel multi-station bag vacuum packing machine, its bag, weighing, filling, vacuuming, sealing and other features on a single machine to complete the .

4 to form a production line. When you need to become more functional for a long time, will all of the features will focus on a single machine on a very complex structure, operation and maintenance is not easy, when can the different functions, efficiency, matching the success of several machines can be a more complete portfolio of production lines.

5, using the relevant new technologies. Extensive use in packaging methods to replace the inflatable packaging vacuum packaging, the inflatable component, packaging materials and inflatable packaging machine to the study closely integrated; in control technology, greater use of computer technology and microelectronics technology; in the application of heat pipe sealing and cold sealing technology, an advanced device can also be directly installed in the vacuum packaging machine, such as the installation of a computer-controlled combination of coarse-grained materials, high-precision scales; in rotation or vacuum packaging machine, the application of advanced high-speed circular surface cam indexing machinery.
