Abstract

The invention discloses a production process for blowing, printing and manufacturing a common express bag, relates to the technical field of express bag production, and aims to solve the technical problem that the strength of the side edge of the express bag is low. According to the technical scheme, the method is characterized by comprising the steps of material mixing, heating melting, film blowing, color printing, bottom end heat sealing, side edge heat sealing, cutting and the like. The invention aims to provide a production process for blowing, printing and manufacturing a common express bag.

Description

technical field [0001] The invention relates to the technical field of express bag production, more particularly, to a production process of blowing, printing and bag making of a common express bag. Background technique [0002] Courier bags refer to the bags used in the express industry to transport documents, documents, materials, goods, etc. At present, plastic courier bags made of polyethylene materials are mostly used, which have the characteristics of low cost, convenient use and good waterproof performance. . [0003] In the production process of the existing courier bags, color printing and cutting are usually performed directly after the film is blown, and then the bottom of the courier bag is heat-sealed. The two sides of the courier bag are folded and squeezed for a long time after storage and transportation, which is prone to occur. damage, thereby affecting the quality of the courier bag. [0004] Therefore, a new technical solution is urgently needed to solve...
