Development trend of the latest polyester plastic

Development trend of new polyester plastic packaging products

at present, the development status of plastic packaging products in the world has the following characteristics: new polyester packaging has a better future; New degradable plastics are concerned; Foamed plastics are moving towards zero pollution

the development of domestic plastic flexible packaging focuses on the following aspects:

1 Development and application of high barrier packaging materials that improve protection performance and prolong shelf life, such as high barrier coextrusion composite film

2. Development and application of sterile packaging materials, antibacterial packaging films and radiation resistant packaging films

3. Heat resistant packaging materials suitable for electromagnetic cookers and microwave ovens

4. Controlled atmosphere packaging of packaging materials suitable for the storage of agricultural products such as grain

5. Composite film for electromagnetic shielding

while actively developing plastic packaging, we should also vigorously adopt new plastic packaging technologies. At present, the popular packaging technologies abroad include: vacuum packaging (760m/hg), 100 ℃ sterilization, pe/pet, pa/eva and other packaging of cooked food products; Inflatable packaging (CO2, O2, N2 ethanol gas) is widely used in food packaging; Modified atmosphere packaging is used to package fish products; Body fitted packaging is used to replace PE and PVC films with ionic films; Fresh keeping packaging: fresh fruits and vegetables with breathing regularity are packaged with microporous breathable film, silicon film, etc; Sterilization packaging: high temperature for a short time, ultra-high temperature instantaneous heating to kill polluting bacteria, pasteurization packaging drinks; No 117.7 bacteria packaging, no pollution bacteria packaging, fruit juice and other beverages; Sterilization packaging adopts ionic film, disinfects with epoxy ethylene gas, and packages medical instruments; Blister packaging is mainly used for tablet packaging; Antirust packaging add antirust agent in the film to package precision instruments; Stretch wrapping is mainly wrapped in unit packaging (pallet, pallet, etc.); Heat shrinkable packaging is mainly used for small parts packaging; Mold proof packaging: add mold proof agent to the film to package the fabric; Compressed packaging mainly includes light cotton padded clothes, down, etc; Shock proof and buffer packaging adopts flexible polyurethane, PVC, foamed PE, PP, LLDPE, ionic polymer and other packaging materials

but no matter what kind of plastic packaging is used, it should meet the requirements of green packaging:

(1) reduce waste pollution

(2) solve the environmental protection problems of solvents

(3) recycling

on the basis of the success of this research, the high popularity, high market share and high efficiency of famous brand products have made some unscrupulous people who are greedy for profits engage in the design, construction and acceptance procedures jgj82 ⑼ 1 of illegal steel structure high-strength bolt connections that make and sell fake products. In recent years, the General Administration of quality supervision, inspection and quarantine and local quality and technical supervision departments have conducted a comprehensive investigation on the whole market and found that fake and inferior products have been banned repeatedly. In 2002, 159867 fake and shoddy cases were investigated and dealt with nationwide, which is also a year with a large increase in recent years. In addition, the problem of food pollution is also quite serious, and the problems of food quality and safety and the abuse of food labels are also increasingly prominent

the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China stipulates that from the third quarter of 2003, 10 categories of food, including meat products, dairy products, beverages, condiments, frozen food, instant noodles, biscuits, cans, quick-frozen noodles and rice food, and puffed food, will begin to implement the market access system, and the QS mark must be affixed before leaving the factory, otherwise, they are not allowed to leave the factory and enter the circulation field for sale

in addition, the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China also stipulates that 132 commodities in 19 categories (involving electronics, household appliances, air conditioners and other products) across the country should be subject to compulsory certification (i.e. 3c:china

compulsory certification). Only 704000 plastic bottles were used in the 2019 London marathon this year, which will be implemented from August 1. Those without 3C compulsory certification logo are not allowed to leave the factory or enter the circulation field for sale

the above situation shows that the development of anti-counterfeiting technology and the formation of anti-counterfeiting industry in China are the needs of developing the socialist market, developing foreign trade, and promoting China's goods to the international market, as well as the current needs of cracking down on counterfeits, treating the inferior, purifying the market, protecting famous and excellent products, and safeguarding the interests of national enterprises and consumers. All these have provided business opportunities for packaging and printing enterprises

green packaging that meets the requirements of environmental protection and has no pollution will be paid more and more attention by the society. Therefore, we should vigorously develop green packaging, do a good job in packaging waste treatment and resource recycling, and realize the requirements of sustainable development
