At present, plastic packaging has an increasing share in the packaging industry, and the amount of discarded packaging materials left behind is also increasing year by year, posing a great threat to environmental protection. Green and environmentally friendly packaging has also become increasingly important. Therefore, it is necessary to vigorously carry out green packaging, focus on the disposal of discarded packaging materials and the recycling and reuse of resources, and meet the requirements of sustainable development.

With the increasing proportion of plastic packaging in the packaging industry, the requirements for it are also increasing. Green environmental protection is one of the requirements. Plastic packaging information enterprises can refer to the following aspects for further improvement and progress: innovation and development of new plastic materials and processing skills, making more functional plastics become packaging materials, and using the high functionality of new materials to reduce packaging materials. Promote the progress and development of plastic blending skills, new plastic additives, and application skills, while ensuring that plastic packaging materials are non-toxic, hygienic, and environmentally friendly, use low-cost skills to improve the functionality of plastic packaging materials, and provide possibilities for quantity reduction.

Further improve plastic recycling and processing skills, significantly increase the recycling and utilization rate of plastic packaging materials, improve and eliminate the risk of white pollution caused by plastic packaging materials, and increase resource utilization rate; Developing bio based plastics, effectively regulating the degradation time and cycle of bioplastics, while fully utilizing the function of bioplastic packaging materials, to reduce and eliminate the pollution and impact of plastic packaging materials on the ecological environment. Through independent research and technological innovation, the cost of new materials and skills for plastic packaging has been reduced, avoiding the problem of many plastic materials that are suitable for green packaging not being widely used due to high costs; Carry out advanced packaging techniques such as intelligence, utilize the characteristics of some plastic packaging materials such as edibility and water solubility, reduce the occurrence of packaging waste, and improve the safety and environmental protection functions of plastic packaging.

At present, the share of plastic packaging in the total output value of the packaging industry in the market has exceeded 30%, becoming a new force in the packaging industry, playing an irreplaceable role in various fields such as food, beverages, daily necessities, and industrial and agricultural production. The plastic packaging profession will have three major development trends in the future: plastic packaging will move towards greening, and plastic packaging waste has attracted widespread attention from society. Strengthening the scientific management and application of plastic packaging, maximizing the recycling and utilization of discarded plastics, and gradually developing and using degradable plastics. In China, degradable plastics have been widely developed, and vigorously developing and promoting the use of degradable plastics is an urgent task.

Plastic packaging will move towards lightweighting, reducing the weight of packaging. Lightweighting refers to using less information to produce packaging, reducing the weight of packaging, which is beneficial for the environment and enterprises. Generally speaking, containers such as plastic bottles, cans, hoses, and caps are simpler to achieve weight reduction.
