The plastic packaging of express delivery is a low-grade and basic material. It is not difficult to find that most express plastic packaging is gray-black, and 70% to 80% of express delivery use it for packaging. This common packaging is made of "recycled materials". Recycled materials are waste materials in production or obsolete materials after use. The materials formed after reprocessing are easy to volatilize under special conditions.

At present, plastic express bags made of polyethylene (PE) materials are widely used in China, which have the characteristics of low cost, convenient use and good waterproof performance.

To sum up, most of the plastic packaging materials used for express delivery are made of recycled PE and recycled PP. With the control of disposable plastic packaging products in various provinces and cities in China, the demand for plastic packaging bags will gradually decline in the later period. Therefore, the demand for express packaging products Replacement will be faster and faster.
