Abstract

The invention discloses a plastic packing bag for express delivery, and relates to the technical field of plastic products. The plastic packing bag for express delivery comprises an inner layer, a pressure-resistant middle layer and a wear-resistant outer layer, wherein the inner layer is made of degradable plastics; the anti-vibration middle layer is made of an air cushion film; and the wear-resistant outer layer is prepared from the raw material components: polyethylene, polyimide, glass fiber, talcum powder and polyphenylene sulfide. Compared with the prior art, the plastic packing bag forexpress delivery provided by the invention is provided with the anti-vibration middle layer and the wear-resistant outer layer, the anti-vibration middle layer is made of the air cushion film, and airis fully filled in the air cushion film middle layer, so that the plastic packing bag is light in weight and high in resilience, and has anti-vibration and wear-resistant performances; and the wear-resistant layer adopts the polyimide added with the glass fiber and the talcum powder as the material so as to have an excellent wear-resistant performance, so that under the rough parcel delivery manner, the probabilities of crushing articles in parcels and wearing the packing bag are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to 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 workload of logistics perso...
