Abstract

The invention discloses a manufacturing method for express plastic packaging bags, and relates to the technical field of plastic products. A packaging bag includes an inner layer, a pressing preventing middle layer made of an air cushion film and an abrasion resistant outer layer; the manufacturing method includes the following steps: making an abrasion resistant plastic film of the abrasion resistant outer layer; sleeving a degradable plastic inner layer by the abrasion resistant outer layer; adding the air cushion film between the inner layer and the outer layer; sewing the outer layer, the middle layer and the inner layer together to obtain the packaging bag. Compared with the prior art, the method has the advantages that the manufacture is simple, the manufactured packaging bag is light, elastic and has the shock-proof and abrasion resistant performances as the shock-proof middle layer made of the air cushion film and the abrasion resistant outer layer are arranged and the air cushion film middle layer is filled with air; as the abrasion resistant layer adopts polyimide added with glass fiber and talcum powder, excellent abrasion resistance is achieved, and the probabilities of crushing damage of objects inside packages and abrasion damage of package bags are greatly reduced in case of crude package conveying manner.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to a method for making a plastic packaging bag for express delivery. Background technique [0002] In the past, people generally used paper envelopes when express mail, the moisture resistance of paper envelopes is not good, and the surface is easy to be worn out; compared with paper envelopes, plastic flexible packaging has outstanding advantages such as moisture resistance and barrier properties , and the cost is low, but ordinary plastic packaging bags are easily worn out because of their thin layer. [0003] Nowadays, with the development of the logistics industry and the fast pace of life and work, people focus their shopping on the Internet. As the volume of online shopping continues to expand, the demand for packaging bags for packaging objects also increases. Every day A large number of packages need to be packaged and transported, which greatly exceeds the workloa...
