New varieties of plastic packaging materials continue to emerge
With the increasing proportion of plastic packaging in the packaging industry, new types of plastic packaging materials are also emerging, at present, on the scale of its production, China's production of plastic packaging materials, has far exceeded the western developed countries and Japan, ranking first in the world, its development speed is amazing, encouraging.

The most striking of the new polyester packaging in the plastic packaging is the application of polyethylene naphthalate, which is a new type of polyester packaging material with good gas barrier properties, UV resistance and heat resistance. In this regard, the extruded foamed PP sheet developed by the Italian A- MUT company is the latest development of foamed plastic products.
Because metallocene polymers have many advantages, such as good processing performance, high strength, high rigidity and good transparency, they have received great attention from the packaging industry, and have launched many new products. Metallocene plastic will directly impact PP, HDPE, LLDPE, elastomer plastic market, it is suitable for food packaging, pharmaceutical packaging, shrink film and hygiene products.
The first is the reduction of plastic packaging waste, reducing the production of plastic packaging waste, which should be the primary environmental strategy for plastic packaging. First of all, we should promote the design innovation of plastic packaging, so that plastic packaging can achieve lightweight or thin-walled plastic packaging under the condition of ensuring its basic functions. Technical advances in material synthesis processes to date have been able to provide varieties of plastics for this purpose.
It should be recognized that the recycling of plastic packaging waste materials is essentially different from the recycling of leftove materials in the production process. It is not only a technical problem, but also a social problem. It not only involves economic benefits, but more importantly, social benefits. Or environmental benefits. Therefore, plastic packaging waste recycling industry has a certain degree of public welfare industrial nature.
The recycling of plastic waste should not be treated with the mentality of recycling scraps in the production process. Even in terms of technical issues, there are still certain determinants of the technical and economic effectiveness of waste recycling, which requires great attention.
No matter what kind of plastic packaging is used, it must meet the requirements of green packaging: reducing waste pollution; solving the environmental protection problem of solvents; recycling and reuse. Meet the requirements of environmental protection, pollution-free green packaging, will be more and more social attention. Therefore, we should vigorously develop green packaging, do a good job of packaging waste treatment and resource recycling, to achieve sustainable development requirements.
