Abstract

The invention discloses a method for fusing edges of a paper-plastic composite bag. The fusing method includes: step 1, cutting out two paper-plastic composite sheets of the same size; step 2, separating the two paper-plastic composite sheets Folding; and each of the paper-plastic composite sheets is formed with two folds; step 3, stacking two of the paper-plastic composite sheets, and placing the four folds at a set bonding temperature Two corresponding bonding; step 4, cutting the two bonded paper-plastic composite sheets into a plurality of small sections, and each small section is an accommodation cavity with two openings; step five, sealing the cavity of the accommodation cavity any opening. This edge melting method has high edge melting efficiency and can reduce the defective rate of the produced paper-plastic composite bag.

Description

technical field [0001] The invention relates to a paper-plastic composite bag, in particular to a method for fusing edges of a paper-plastic composite bag. Background technique [0002] At present, when producing paper-plastic composite bags, the plastic film for producing paper-plastic composite bags is generally cut into multiple sections, and then each section is processed independently, including processing steps such as edge melting and creasing for each section. Each unformed paper-plastic composite bag is an independent segment, which requires a certain degree of flexibility during operation. Therefore, factories generally use manual operations. As a result, the efficiency of edge fusion will be low, and manual operation will inevitably increase the defective rate of paper-plastic composite bags. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a method for fusing edges that has high fusing efficiency and can reduce the def...
