At present, the development status of the world's plastic packaging products has the following characteristics: the new polyester packaging has a promising future; the new degradable plastics are concerned; the foamed plastics are moving toward zero pollution.
The development of domestic plastic flexible packaging focuses on the following aspects:
1. Improve the protection performance and extend the development and application of high barrier packaging materials such as high barrier coextrusion composite film;
2. Development and application of aseptic packaging materials, antibacterial packaging films, and radiation resistant packaging films;
3. Heat-resistant packaging materials suitable for heating in induction cookers and microwave ovens;
4. Controllable air-conditioning packaging for packaging materials suitable for the storage of agricultural products such as grain;
5. Composite film for electromagnetic shielding.
While actively developing plastic packaging, we must vigorously adopt new plastic packaging technologies. At present, foreign popular packaging technologies include vacuum packaging (760m/hg), 100Â°C sterilization, and packaging products such as PE/PET and Pa/EVa. Inflatable packaging (Co2, O2, N2 ethanol gas) is widely used for food packaging; modified atmosphere packaging is used for packaging fish products; body packaging is used for ion film to replace PE and PVC film; fresh packaging is made of microporous breathable film, Silicon film and other packaging have fresh fruits and vegetables with respiratory regularity; sterilized packaging with high temperature for a short time, ultra-high temperature instantaneous heating to eliminate contaminating bacteria, pasteurized packaging beverage; aseptic packaging non-polluting bacteria packaging juice and other beverages; sterilization packaging Ionic film, sterilized with Ethylene Oxide gas, packaging medical equipment; blister packaging is mainly used for tablet packaging; rustproof packaging is added with anti-rust agent packaging precision equipment in film; stretching wrap is mainly used for unit loading (tray, pallet) Wrap-wrapped packaging; heat-shrinkable packaging is mainly used for small parts packaging; mildew-proof packaging is added to the film with anti-mold agent packaging fabric; compression packaging is mainly packaged with light cotton clothing , down, etc.; shockproof buffer packaging using soft polyurethane, PVC, foamed PE, PP, LLDPE, ionic polymer and other packaging materials technology.
But no matter which plastic packaging is used, the requirements for green packaging must be met:
(1) reduce waste pollution;
(2) Solving environmental problems of solvents;
(3) Recycling and reuse issues.
The high reputation, high market share and high efficiency of brand-name products have made some unscrupulous lawless people take the illegal activities of counterfeiting and selling fakes. In recent years, the AQSIQ and local quality and technology monitoring departments conducted a comprehensive investigation of the entire market and found that counterfeit and shoddy products have been repeatedly prohibited. In 2002, there were 159,867 cases of counterfeit and shoddy cases investigated and handled nationwide, which was also a year of great growth in recent years. In addition, food contamination problems are also quite serious, and food quality and safety issues and food label abuse issues are becoming increasingly prominent.
The General Administration of Quality Supervision, Inspection and Quarantine has stipulated that from the third quarter of 2003, meat products, dairy products, beverages, condiments, frozen foods, instant noodles, biscuits, canned foods, quick-frozen rice foods, and puffed foods began to implement market access. The system must be stamped with the QS mark at the factory. Otherwise, it is not allowed to leave the factory and enter the circulation field for sale.
In addition, the General Administration of Quality Supervision, Inspection and Quarantine also stipulates that 132 kinds of commodities (including electronic, home appliances, air conditioners, etc.) in 19 categories of the country must implement compulsory certification (ie 3C: ChinaCompulsoryCertification), which will be implemented from August 1 this year. The 3C compulsory certification mark is not allowed to be shipped from the factory or in the circulation field.
The above-mentioned situation shows that the development of China's defense technology and the formation of the anti-counterfeiting industry are the needs of developing the socialist market, developing foreign trade, and promoting the need for China's commodities to enter the international market. It is currently cracking down on counterfeiting, purifying the market, protecting famous cities, and safeguarding the country. The needs of business and consumer interests. These have provided business opportunities for packaging and printing companies.
Environmentally friendly, non-polluting green packaging will receive more and more attention from the society. Therefore, we should vigorously develop green packaging, do a good job in the recycling of packaging waste and the recycling of resources to achieve sustainable development requirements.
Organic Pigments are insoluble organics that are typically added to the substrate in a highly dispersed state to color the substrate.
Common varieties are azo pigments (acetyl arylamine, 2-naphthol, pyrazolone, 2-hydroxy-3-naphthoic acid or 2-hydroxy-3-naphthoyl aromatic amine, etc.), lake (barium chloride) , calcium chloride, manganese sulfate, Phosphoric Acid-molybdic acid, phosphoric acid-tungstic acid, tannic acid), phthalocyanine (phthalocyanine), quinacridone pigment (isoindolone pigment, benzimidazolone pigment).
