Vacuum packaging is known as non-container packaging, can save a lot of raw and auxiliary materials, packaging, reducing packaging waste, in line with the global advocate of moderation and reduction of packaging requirements. Vacuum packaging is the 20th century, developed 80 new technologies and new packaging materials, this new technology and new materials, began to be used on tablets, pills, health pills, small pieces of candy packaging and other solid. With the gradual rise of plastic packaging, vacuum packaging more widely. In recent years, beginning in our vacuum packaging used for small electrical appliances, handicrafts, toys, footwear and some electronic packaging and turnover. Such as MP3, headphones, USB, toys, batteries, crafts, sports shoes, packaging and finished products such as metal stamping parts, lathe parts, computer connectors, electronic components and other materials flow.

The main advantage of vacuum packaging is to save the raw and auxiliary materials, light weight, easy transportation, good sealing performance, environmentally friendly green packaging requirements; to any shaped packing products, packing materials without the addition of buffer; be visible and transparent packaging products beautiful appearance, easy to sell, and are suitable for mechanization and automation package, modern management easier, save manpower and improve efficiency.

Vacuum packaging is dedicated to the packaging machinery, packaging in recent years as to the mechanization and automation of the direction of the development, production thermoforming packaging machinery manufacturers to develop rapidly, there are many domestic and international plastic packaging specializing in the production of vacuum equipment manufacturers. Although the structure of vacuum forming packaging machine types vary, but the principle is basically similar to. Vacuum packaging is the working principle: plastic machine plastic sheet through the heating oven, the heating or cooling of the principle, the beginning of soft sheet Jian, larger. Then in a particular mold or aluminum mold on a vacuum molding. Depending on the product requirements of the molding of plastic to press cutting.

Vacuum skin packaging is known as non-container packaging, can save a lot of raw and auxiliary materials, packaging, reducing packaging waste, in line with the global advocate of moderation and reduction of packaging requirements, vacuum skin packaging is the 20th century, 80 s developed new technology and new packaging materials, this new technology and new materials, began to be used on tablets, pills, health pills, candy and other small pieces of solid packaging. With the gradual rise of plastic flexible packaging, vacuum skin packaging applications more widespread. In recent years, China began to vacuum skin packaging products for the packaging of small appliances. The packaging of many large household appliances are the upper and lower part of the package supported by a fixed rigid packaging, the external use of high strength transparent plastic film. Many small appliances such as burners, DVD, EVD and other packaging products are beginning to use vacuum packaging, it is the only protection for the edges and corners, not the overall packaging of goods, and paper profiles as nursing side, angle , retaining the top, bottom protection and other protective packaging materials, making it environmentally friendly, cost, and so to be a comprehensive reflection of commercial marketing and opened up new ways of packaging reduction.

From the packaging design performance point of view, Food packaging design requirements can be divided into two parts, internal and external:

The inherent requirements of food packaging design: the inherent requirements of food packaging design is through the packaging to make food packaging design in its quality and quantity to achieve the technical requirements.

Food packaging design strength requirements: refers to the package design to protect the packaged food in storage, stacking, transport, handling the process of resistance to various destructive outside, such as pressure, force of impact and vibration. Food packaging design strength requirements related factors, the main mode of transport (such as cars, aircraft), stacking form (such as multi-layer stacking, cross-stacking) and environment (such as climate, sanitation) and other three factors.

Barrier food packaging design requirements: barrier food packaging design is one important performance. A lot of food in storage, due to errands barrier packaging design and quality of food flavor changes, and ultimately affect the quality of food. Barrier packaging design requirements determined by the characteristics of the food itself, its characteristic manifestations of external barriers, internal barriers or selective blocking and so on. Barrier material with air, water, oil, light, microorganisms and so on.

Respiratory requirements of food packaging design: some are exported to other foods such as fresh fruits and vegetables, during storage in the package design remains respiratory function, therefore, such packaging material or container with a breathable, or able to control respiration, to achieve the preservation purposes.

Nutritional requirements of food packaging: food storage in the packaging process, the gradual loss of nutrients, so food packaging packaging design should be conducive to the preservation of food and nutrition, better packaging packaging design is locked through nutrition.

Other requirements: food packaging packaging design there are many inherent requirements, such as heat resistance, sunlight requirements, shatterproof requirements, moisture requirements.

External requirements of food packaging: food packaging packaging design is the use of the external requirements of food packaging reflects the characteristics, performance, image, outside of food and means of visualization and manifestation.

Safety requirements for food packaging design: the safety of food packaging design, including health and safety, safe handling and use of security and so on. Health and safety is the food packaging materials should not contain harmful substances; in the packaging design technology, so that after treatment in the nutritional content of food, color and taste as much as possible unchanged. Handling safety is the packaging design to ensure the safety of transport problems in the handling process should also include consumers shopping after extraction and purchase portable security. Use of safety is to ensure that consumers in the open, not to be consumed during the injury.

VisiPak recently partnered with Shorr Packaging Corp to develop thermoformed trays to package a GPS device. The plastic packaging trays were specifically designed with future modifications in mind to keep costs low for Shorr Packaging as the product changed with new innovations.

Shorr Packaging Corp. is one of the largest independent packaging distribution firms in the nation. From packaging equipment to consultant services, Shorr provides expertise in integrated packaging solutions and integration is key. With an exhaustive list of strategic relationships in manufacturing equipment and consumables, Shorr delivers high quality products and services.

Late in 2008, Shorr began a business relationship with VisiPak purchasing a thermoformed plastic clamshell. About a year later, when a new product for Shorr developed, VisiPak was called into action once again. One of the restrictions submitted related to the size of the new plastic tray packaging container. The new protective packaging trays were to be a specific depth and width, with height the only dimension that could vary. The clear plastic packaging tray would protect an expensive new product and then be inserted into a corrugated box, complete with an outlet for a handle.

The new product, a GPS system for the agricultural industry, is used to guide tractors with impeccable precision and is a costly unit demanding shipping protection. This is where the VisiPak design engineering team stepped up to the plate. By closely analyzing the components of the GPS system itself, the VisiPak engineers arrived at a design that would not only satisfy all existing requirements, but also provide for less expensive tooling on future revisions by developing interchangeable mold bases.

As is well known, technology is always changing and the various components of the GPS unit may change in future versions. VisiPak packaging design engineers are well aware of this concept and with this in mind, designed a new thermoformed plastic shipping tray with an interchangeable mold base. Simply put, a base mold forms the outer frame of the thermoformed tray and another interior mold, which contains the various cavities for the various GPS components, is inserted to form a single tray. This means that the existing cavitations can be easily modified, saving thousands of future tooling costs.

After studying the GPS components, VisiPak design engineers concluded a two-tier shipping tray would best accommodate the system. Without changing the depth or width of the current design, one part of the plastic tray would contain the screen and a second tray, the tray made from the interchangeable mold base, would hold the various other components of the GPS unit. The two clear trays would then stack and slide into the corrugated box, snugly securing all contents within. Also featured in the design of the plastic tray packaging is the contour or scoop allowing for the handle of the outer box.

Not only did the VisiPak design engineers create the thermoformed package protection required, but because of their perception of advancements in technology, they were able to consider not only the moment, but the future as well. With this type of service, Shorr can conceivably save a third of future tooling costs should variations of the GPS device require new packaging.

According to “industrial production permit regulations,” regulations, next month, all food paper packaging, containers, etc. must sell QS market access being available, unable to obtain access to the production enterprise will fade out.

Daiyue quality monitoring stations, said law enforcement officers, from September 1, the food paper packaging, paper containers for food with the QS Manager of the formal investigation into all the food paper packaging, containers and other market access must be listed QS sales, otherwise they would be investigated.

“As the costumes food and beverage containers, paper cups, quality of the product is safe, very important to consumers. Quality supervision departments will have cup of raw materials used in pulp production enterprises, waxed floor wax, etc. with repeated testing, then, only full compliance of the company to get access, can not get access to the company will exit the market after September 1. “law enforcement personnel, to be included in the first directory of food paper packaging, containers and other products, including packing and containers Class of 21 varieties of two major categories, including food packaging cellophane paper, food packaging, food packaging board, brown paper and, while the food is often used with paper containers, including paper bag, paper cans, paper cups, paper tableware, paper and so on, which usually covers almost all direct contact with food packaging.

“For example, instant noodle bowl, hamburgers, sandwiches and other cooked food like wrapping paper, cookie baking paper, candy, preserved fruits, etc. wrapping paper, tea cake, wrapping paper, tea bag, wrapping paper, the Class of wax paper food packaging, ice-cream wrapping paper, etc., all within the scope of management in QS. “law enforcement officers explained that under the new regulations, not been included in the first directory of food paper packaging, container production permit card company, not the production of the product; any unit or individual may sell or use in business activities without the production license of the product. “Inspection process, we will be in accordance with relevant laws and regulations, investigate and punish those who violate the regulations.”

Here, quality supervision staff to remind consumers buy disposable cups, be sure to look for QS logo. After September 1, consumers purchasing a paper cup not found to QS mark, may be reported to the quality supervision departments. In addition, to carefully review whether the sign package labeled “product name, producer name and address, product performance standards, production date, shelf life” and other countries require labeling of the contents of the label if the contents of cups incomplete or not specification, it is best not to buy.

Packaging design is the combination of art and natural sciences, applied to the product’s packaging to protect and beautify the area, it is not a generalized “art” is not a simple decoration, but with science, art, material, economic, psychological, market Integrated elements such as the embodiment of multi-functional.

The main role of packaging has two: one is to protect the product; second, beautification and promotional products. The basic task of packaging design is a scientific, economic, complete packaging shape, structure and interior design.

(1) Packaging Design

Packaging Design, also known as physical design, most of that shape containers. It is the use of aesthetic principles, by shape, color and other factors change, will have the functionality and appearance of the beautiful packaging containers modeling, visual forms. Containers must be able to reliably protect the product, must have good appearance, needs to fit with the economic and so on.

(2) Packaging Design

Packaging structure design is from the protective packaging, convenience, reusability and other basic functions and the actual production conditions, based on scientific principles to the packaging of the external and internal structure derived from the design for specific consideration. A good structural design should be to effectively protect the primary functions of goods; Secondly, we should consider using, carrying, display, the convenience of shipping, etc.; also be able to reuse as much as possible into account, can display the contents and so on.

(3) Packing Design

Packing design is design, text, color, relief and other art forms, highlighting product features and image, and strive to form compact, novel designs, bright colors, clear text, decorative and landscaping products to promote product sales. Packaging and decoration is an integrated science, is both a practical art, it is an engineering technology, arts and crafts and the combination of engineering and to consider the marketing, consumer economics, consumer psychology and other disciplines.

A good package design, packaging design, structural design, decoration design the three organic unity, the only way to fully play the role of packaging design. Moreover, the packaging design not only involves the two major academic technology and the arts, it also involved in their respective areas of many other related disciplines, therefore, to get a good package design is the need for some hard work under the.

In recent years, the food packaging industry in China developed rapidly, far more than other manufacturing industries. According to experts speculate that a period of time in order to meet future food packaging industry in China’s fast development needs, there will be five major food packaging machines dominate the market:

One bag, filling, sealing packaging machinery. Current domestic production of more than 100 manufacturers of such machinery, the output reached 15 million units. Bag making, filling, sealing the trend of packaging machinery modular structure, more high-speed, high stability, transmission machinery is simple, adaptive closed-loop control.

Second, the metal packaging container processing equipment. China metal packaging container processing machinery manufacturing industry has taken shape, first, the development trend of such products to improve product performance, increase yield and material utilization, is to accelerate the improvement of product technology, development of mercury-free welding and high-performance high-frequency welding power supplies.

Third, corrugated boxes (board) production equipment. Over the past decade, China’s corrugated box machinery industry developed rapidly, corrugated board line product range from the development to printing slotting machine, cardboard gluing machine, cut machine and other product series, the future direction of First Gaosu Plants, 2 corrugated cardboard boxes is the light equipment.

Fourth, pulp molding processing equipment. Processing equipment, paper tableware in China at present is relatively small scale of production, processing equipment, high prices. Pulp mold tableware processing machinery in the future should reduce the cost of forming heated mold, improve heating methods to reduce power consumption costs, increase production and so increase the research.

Fifth, vacuum packaging machinery. China’s many production of vacuum packaging machinery business to the main assembly, the main variety is mainly semi-automatic operation, automatic continuous, large vacuum chamber and suitable for liquid packaging, vacuum packaging machinery less, domestic general lack of efficient, dedicated vacuum packaging machine .

Quick packaging machinery will follow the current trends in order to facilitate customers, research and development of better packaging machinery.

Cellphone designs that hide the screen when not in use have

traditionally been separated into two designs, the clamshell and the

slider. People have preferred the clamshell because they’re compact,

and others like the slider because they usually have large screens.

Like Pandas, Cellphone’s forced the two to mate for the good of the

species, and out popped the Sliding-Clamshell.

When you flip the phone open, the body becomes a track for the screen

to move up. There’s enough room for the standard keys plus an iPod like

click wheel. This design seems like it will make phones more compact,

but thicker. Is that a sliding-clamshell in your pocket or did you just

have genital enhancement surgery?

Definition bags

Bag is a bag used for packaging of various products, widely used in daily life and industrial production.

Classification bags
Press material is often divided into plastic clamshell bags, cloth bags, paper bags and so on.
By use of terms can be divided into food trays packaging bags, industrial bags and specialty bags.
According to environmental standards, can be divided into green bags and non-environmentally friendly bags.

The development of bag
The development of bags has gone through four distinct phases: the primitive stage of packing bags, big bags stage, the small packets of bagging stage and gradually into the current environmental (green) bags of the new stage. With the development of commodity economy, packaging of the commodity itself, more and more significant, it has become a kind of commodity production is no longer dependent on the particular product, a kind of all commodities can not be separated, and widely used products.

1. Plastic clamshell products produced fused marks of reasons:
1) due to melting the material solidified in the confluence of spearhead part of the cooling of the fused strip without causing marks.
2) due to volatile materials, the air still blocked
3) residual cavity with release agent.
2. Associated with knowledge:
1) using a gate, without the direction of the material from the confluence of the two products generally do not have fused marks, in addition, if the Want to avoid changing the gate can only be fused marks the location of so fused marks are not visible, or appear to occur in the location of eyesore.
2) mold on the pins (in the product on the hole) usually occurs fused marks.
3) has been closed due to air arising from the phenomenon of fused mark is very large, it is necessary to make the air completely escape.
4) it also uses this method: To generate fused marks in a place where the extra sheets in the product, and then then slice Cut off.
5) release agent over molten material Ershi float part of the advance party sent to the cavity, melting occurs certain knot mark.
3. Solution:
1)An instant: Improving injection speed, mold temperature increased to raise the temperature of barrel increase injection pressure.
2)short-term: the increase of gas escape slot.
