Why do PE bags produced by Guangzhou Plastic Bag Factory stick together?

(1) The curing temperature is on the high side, and the slip agent loses its function at high temperature, especially in high temperature retort pouch. The smoothness of RCPP is not good, and the friction coefficient is difficult to control after long-term curing at high temperature.

(2) Adhesive permeates the inner surface, which affects the friction coefficient of the substrate film surface, especially when the film is thin and corona treatment is excessive.

(3) The smoothness of the film substrate itself is poor; No slip agent can be added in the process of extrusion compounding. When PE is extruded, the film is very sticky and the friction coefficient is large.

(4) The above reasons will cause problems such as difficulty in drawing materials, deviation of bag electric eyes, different lengths, and poor bag mouth. When the mouth of the bag is blown open by an air nozzle for packaging, the mouth of the bag will stick together again every once in a while.

Sticking the package is caused by the above four problems, so you should pay attention when choosing, or you can go to Ming' an to look at the packaging, which is quite good.
