Green plastic packaging rookie: polyester plastic

At present, the development status of the world's plastic packaging products has the following characteristics: The new type of polyester packaging is more promising; the new type of degradable plastic is of concern; and the foam plastic is moving towards zero pollution.

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

1. To improve protection performance and extend the development and application of high-barrier packaging materials such as high-barrier coextruded composite films for shelf life;

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

3. It is suitable for heat-resistant packaging materials for induction cookers and microwave ovens;

4. Applicable to controlled atmosphere modified packaging of packaging materials such as grain and other agricultural products;

5. Composite film for electromagnetic shielding.

While actively developing plastic packaging, we must also vigorously adopt new technologies for plastic packaging. At present, foreign popular packaging technologies include: vacuum package (760m/hg), sterilization at 100°C, and packaged cooked food products such as PE/PET and PA/EVA. Inflatable packaging (Co2, O2, N2 ethanol gas) is widely used in food packaging; modified atmosphere packaging is used to package fish products; skin packaging is used to replace PE and PVC membranes with ion membranes; microporous ventilation membranes are used for fresh packaging. Silicon film and other packaging with fresh fruits and vegetables with regular breathing; sterilized packaging with high temperature for a short time, ultra-high temperature instantaneous heating off contaminated bacteria, pasteurized packaging beverages; aseptic packaging of pollution-free packaging juice and other beverages; sterilization packaging used Ionic film, disinfected with ethylene oxide gas, packaging medical equipment; blister packaging mainly used for tablet packaging; rust-proof packaging in the film plus rust-proof packaging precision instruments; stretch wrapping mainly with a unit (pallet, pallet (), etc.) Wrapped packaging; heat-shrinkable packaging is mainly used for small parts packaging; anti-mildew packaging in the film plus anti-mildew agent packaging fabrics; compressed packaging mainly light-weight cotton clothing , Down, etc.; shock buffer packaging using soft polyurethane, PVC, foaming PE, PP, LLDPE, ionic polymer and other packaging materials technology.

However, no matter which type of plastic packaging is used, it must meet the requirements of green packaging:

(1) Reduce waste pollution;

(2) Solve the environmental problems of solvents;

(3) Recycling and reuse problems.

The high visibility, high market share and high efficiency of brand-name products have led some unscrupulous criminals to engage in counterfeiting and selling fake products. In recent years, the AQSIQ and local quality and technical supervision departments have conducted a comprehensive investigation of the entire market and found that counterfeit and shoddy products continue to be prohibited.

In 2002, 1,59867 counterfeit and shoddy cases were investigated and prosecuted in the country, which is also a year of significant growth. In addition, the problem of food contamination is also very serious. The problem of food quality and safety and the abuse of food labels are also becoming increasingly prominent.

The General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) stipulates that starting from the third quarter of 2003, the introduction of market access for meat, dairy products, beverages, condiments, frozen foods, instant noodles, biscuits, canned foods, instant frozen rice foods, and expanded foods. System, the factory must be affixed QS logo, otherwise, are not allowed to leave the factory and enter the circulation of sales.

In addition, the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) also stipulates that the nation’s 19 categories of 132 commodities (involving electronics, home appliances, air conditioners, etc.) must be subject to compulsory certification (ie, 3C: China Compulsory Certification) and implemented from August 1 this year. Those who do not have the 3C mandatory certification mark are not allowed to leave the factory and enter the circulation field for sale.

The above situation shows that the development of China's anti-counterfeiting technology and the formation of anti-counterfeiting industries are necessary for the development of the socialist market, the development of foreign trade, and the promotion of China’s commodities to meet the needs of the international market. It is the current anti-counterfeiting, purification, protection, and maintenance of the country. The needs of business and consumer interests. These all provide business opportunities for packaging and printing companies.

In line with environmental protection requirements, non-polluting green packaging will be increasingly valued by the community. Therefore, we should vigorously develop green packaging, do a good job of packaging waste disposal and recycling of resources to achieve sustainable development requirements.
