Green packaging bags are the main trend of the world packaging industry development, and food safety is the focus of the current and future years in China. Both of them have a direct impact on the development of plastic packaging materials. At present, the research and development of green plastic packaging has become the goal of many enterprises. Green plastic packaging materials not only need to be hygienic and environmentally friendly, but also have the function and high performance of packaging. This requires plastic packaging materials enterprises to further improve and enhance in the following areas.

One is to innovate and develop new plastic materials and new processing technology, so that more excellent plastics can become packaging materials, and use the high performance of new materials to reduce packaging materials.

The second is to promote the progress and development of plastic blending technology, new products of plastic additives and application technology. On the premise of guaranteeing the non-toxicity, sanitation and environmental protection of plastic packaging materials, the use of low-cost technology can improve the performance of plastic packaging materials and make it possible to reduce quantities.

Third, improve and improve the plastic recycling processing technology, so that the plastic packaging material recycling utilization rate has been greatly increased, improve and eliminate the plastic packaging material caused by "white pollution" hidden dangers, improve the utilization rate of resources.

Fourthly, the development of bio-based plastics can effectively regulate the degradation time and cycle of bio-plastics, while giving full play to the function of bio-plastics packaging materials, reduce and eliminate the pollution and impact of plastic packaging materials on the ecological environment.

Fifthly, through independent research and development and technological innovation, we can reduce the cost of new materials and technologies for plastic packaging, so as to avoid the problem that many plastic materials conforming to green packaging can not be widely used because of the high cost.

Sixth, the development of intelligent packaging technology means, the use of some plastic packaging materials with edible, water-soluble characteristics, reduce the production of packaging waste, improve the safety and environmental performance of plastic packaging.

How to avoid food contamination by plasticizers and metal elements while ensuring product performance is a problem that must be solved for enterprises to survive and develop. Thirdly, as a member of the society, enterprises must shoulder the corresponding social responsibility, do a good job in the treatment of packaging wastes and the recycling of resources, to achieve the requirements of sustainable development.

At the same time, there are many kinds of product packaging on the market, which also provides conditions for the development of soft packaging. Of course, in the future development of flexible packaging, environmental protection is still its great advantage. With the diversification of consumer market demand, the importance of lightweight packaging attributes is increasingly highlighted in the analysis of printing carbon footprint and the environmental impact of packaging.
