At present, plastic packaging has accounted for an increasing proportion in the packaging industry, and the remaining packaging waste is also increasing year by year, making environmental protection seriously threatened, and green express environmental protection packaging has become more and more important. Therefore, mailing bag manufacturers should vigorously develop green express packaging, do a good job in packaging waste treatment and resource recycling, and achieve sustainable development requirements.

With the increasing proportion of plastic courier packing bags in the packaging industry, the requirements for them are getting higher and higher. Green environmental protection is one of the requirements. Mailing bag manufacturers can make further improvements in the following aspects as a reference:

1. Innovative research and development of new plastic materials and new processing technologies for plastic courier packaging bags

Make more high-performance plastics packaging materials, and use the high performance of new materials to reduce the amount of express packaging materials. Promote the development of plastic courier packing bags blending technology, new plastic additives and application technology, and use low-cost technology to improve the performance of plastic packaging materials. Under the premise of ensuring that plastic packaging materials are non-toxic, hygienic and environmentally friendly, use low-cost technology to improve the performance of plastic packaging materials and provides the possibility of reduction.

2. Improve plastic recycling and processing technology

The recycling rate of plastic courier packaging bags and packaging materials has been greatly increased, and the hidden dangers of white pollution caused by plastic packaging materials have been improved and eliminated, and resource utilization has been improved: the development of bio-based plastics effectively regulates the degradation time and cycle of bioplastics, and makes full use of bioplastics express packaging materials function, reduce and eliminate the pollution and impact of plastic packaging materials on the ecological environment.

Through independent research and development and technological innovation, reduce the cost of new plastic packaging materials and new technologies, and avoid the problem that many plastic express packaging bag materials that conform to green packaging cannot be applied in a large area due to high costs: develop intelligent and other advanced packaging technology methods, take advantage of the edible and water-soluble characteristics of some plastic packaging materials to reduce the amount of packaging waste and improve the safety and environmental performance of plastic packaging.
