Paper bag making is widely used in some industries and has achieved remarkable results. The packaging industry has unique value for the application of value engineering, but for the production of paper bags, glue or other adhesives are used for bonding, sometimes We will find that there is a phenomenon of glue opening in the production of portable paper bags, which is related to the use of adhesives by the manufacturers of portable paper bags. If we analyze in detail, the reasons for the opening of paper bags in the production of portable paper bags are as follows:



1. The viscosity of the adhesive made of gift paper bags is not enough or the amount of glue applied is not enough.



2. Adhesive and gift paper bag making materials do not match.



3. The sticky mouth part of the gift paper bag has been surface processed by laminating and glazing. It is difficult for the adhesive to penetrate the surface layer and penetrate into the paper, and the carton is difficult to stick firmly.



4. The pressure after folding and gluing is insufficient, and the pressing time is not long enough, which is not conducive to the strong adhesion.
