With the increasing proportion of plastic packaging in the packaging industry, new types of plastic packaging materials are constantly emerging. At present, in terms of their production scale, the production of plastic packaging materials in China has far exceeded that of Western developed countries. And Japan, ranking first in the world, its development rate is very alarming and encouraging.
The new polyester packaging is the most attractive in plastic packaging materials. The application of polyethylene naphthalate is a new type of polyester packaging material, which has good gas barrier, UV protection and Heat resistance. Foamed plastics move towards zero pollution In this respect, the extruded foamed PP sheet developed by the Italian company A-MUT is the latest development of foamed plastic products.
Packaging companies vigorously develop metallocene plastics. 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 many new products have been launched. Metallocene plastics will directly impact the markets of PP, HDPE, LLDPE, and elastomer plastics. It is very suitable for food packaging, medical packaging, shrink film, and sanitary products.
In terms of the development policy of plastic packaging, first of all, the reduction of plastic packaging waste and the reduction of plastic packaging waste should be regarded as the primary environmental strategy of plastic packaging. First of all, the design innovation of plastic packaging should be promoted, so that the plastic packaging can achieve light weight or thin wall under the condition of ensuring its basic function. Technological advances in the material synthesis process so far have been able to provide plastic varieties for this purpose.
It should be recognized that the recycling of plastic packaging waste is essentially different from the recycling of scraps in the production process. It is not just a technical problem, but also a social problem. It not only involves economic benefits, but more importantly, social benefits or Environmental benefits. Therefore, the plastic packaging waste recycling industry has a certain degree of public welfare industrial nature.
Recycling of plastic waste should not be treated with the mentality of recycling in the production process. Even on 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: reduce waste pollution; solve the environmental protection problems of solvents; recycle and reuse problems. Green packaging that meets environmental protection requirements and is pollution-free will be increasingly valued by society. Therefore, we should vigorously develop green packaging, do a good job in packaging waste treatment and resource recycling, and achieve sustainable development requirements.
