Plastic containers of beer


71% of the global plastic beer glass bottles, glass bottles used in China is the world's countries with the highest proportion, 80%, however, heavy glass bottles, the impact of intolerance, easy to damage, not only working to keep and bear the inconvenience, but also lead to beer manufacturing and transportation costs rise, affect personal safety. Therefore, plastic containers of beer, has become the general trend had made, with plastic bottles instead of glass bottles of beer the pursuit of increasingly become the target, a variety of plastic beer bottle technology came into being. In recent years, some developed countries or multi-layer composite, such as modification of surface coating technology to improve the resistance of the PET bottle of gas permeability; or the use of heat-setting techniques to improve heat resistance; or the use of new plastic materials (PEN) Forming repeatable filling beer bottles. Beer packaging plastic of the main problems: the cost of higher prices than conventional PET bottles or too high, still need improvement and innovation in technology, safety and environmental protection measures to be implemented. With the plastic beer bottle manufacturing technology of continuous improvement and innovation, mass production, after production costs continue to decrease and the gradual establishment of China's relevant laws and regulations, plastic beer bottles, will also be a growing number of beer manufacturers and consumers to accept and welcome the development of a bright future. (Fang) Color identification of harmful bacteria present food packaging advent of Canadian scientists has developed a dye coated with antibody and plastic bags. It is packaged with a certain quantity of food in the presence of harmful bacteria, the surface of the packaging bag can be reflected directly, people can identify with one. The standard polyethylene food packaging material, placed on the inner surface of its specific antibody, the antibody layer coated with a layer of gel, the gel containing the same antibodies and with a special chemical compound used for the fuel, gel is a lot of holes in a plastic wrapping, it will direct contact with food. When harmful bacteria infected food, begin to reproduce, they will pass through the innermost hole on the wrapping paper into the gel layer. Then the gel layer is activated in the antibody binding with the harmful bacteria to produce the color reaction, so that harmful bacteria coloring. The company has developed this new Roche bags can detect bacteria, Salmonella, Campylobacter and E. coli 0157 and other 4 kinds of harmful bacteria. United States and Europe approved the UV blocking agent used in food packaging Recently, the U.S. FDA has approved one kind of UV blocking agent in the United States on food packaging applications. Previously, the product also received the EU's application certification: a specially designed UV-blocking agent that can protect the package of goods from UV damage, extended storage of goods, and comprehensive display of items. Sunlight and ultraviolet fluorescent lamps contain the warehouse,[link widoczny dla zalogowanych], and the product can effectively block ultraviolet rays to prevent items inside the package in color, smell, taste and nutritional value of any change. Transparent packaging materials, allowing consumers about product quality and appearance; and add in a transparent PET packaging materials in the UV-blocking agent that can protect the package of goods from UV damage, in addition, the UV blocking agent also has other the application,[link widoczny dla zalogowanych], including personal care,[link widoczny dla zalogowanych], household products and food and beverage packaging. U.S. wheat starch for packaging recently,[link widoczny dla zalogowanych], the American Chemical Society meeting shows the results of the study, U.S. researchers has finally found a low-cost, environmentally friendly fast-food packaging materials. This material is made from wheat straw fiber and starch in the grain as raw materials to make the box can be completely degraded. Although previously been made out of potato starch packaging, but the price of wheat starch, potato starch is much cheaper than that. And. Wheat starch as raw material of the box, than with potato starch for packaging materials and better insulation properties. In the past, people mainly used as packaging material polystyrene, polystyrene although lighter, easy to make, good insulation, but can not be degraded, but also contain ozone-destroying CFCs. Side board in addition to more expensive,[link widoczny dla zalogowanych], heavier and produce more complex, the thermal performance is also poor. Japan recently launched a new paper, cans, Toppan Printing Company invented a high degree of sealing and bactericidal, under normal temperature conditions in the new long-term preservation of paper cans, the food storage capacity of not less than metal cans. The current paper can be used for beer, juice and other beverages, and well received. The main features of the paper can be: more than cans, glass light; capable of filling high temperatures, the use of aluminum foil edge protection, reducing the oxygen permeability, consequently flow at room temperature shelf life of up to one year; tank body material from the polyethylene, paper, aluminum, polyester (PET) and other compound from strength to ensure that cans can flow directly to a tank prototype, so as with the traditional round cans, vending machines available for use; recycling convenient, pollution-free burning. The design of this paper can tank barrel concave side, thus increasing the strength of the tank will not result in flat cans phenomenon, which is in the past the process of development can
