AI Technical Summary

Technical Problem

Existing packaging bags are prone to slipping during the stacking process, mainly because the gas in the bags cannot be removed, resulting in the bags not being able to fit completely together, and the smooth surface causes relative sliding, affecting stacking stability and transportation efficiency.

Method used

Vent holes are set on the side of the packaging bag to remove the gas inside the bag, and anti-slip blocks are distributed at intervals on the surface of the bag to increase the friction coefficient. By removing the lubricant during the preparation process and applying the lubricant after corona treatment, the distribution of the anti-slip blocks and the coating method of the composite film are optimized to ensure that the bags are not easy to slip during the stacking process.

Benefits of technology

It achieves stable fitting and anti-slip effects for packaging bags during stacking, while ensuring smooth production during the bag-making process, avoiding bag breakage caused by excessive friction, and reducing production costs and the need for equipment improvements.

Abstract

The present application provides a degassing and anti-slip packaging bag and a preparation method thereof, comprising a bag body, with degassing holes provided on both sides of the bag body, and anti-slip blocks provided at intervals on both surfaces of the bag body. The present invention achieves the purpose of complete fit between bags by punching holes on the side of the bag so that the bags are squeezed by the bags above after being stacked, and the gas in the bags is continuously discharged. In addition, by intermittently arranging anti-slip blocks on the surface of the bag and using a film without a lubricant to increase the friction coefficient of the outer surface of the packaging bag material, a larger friction coefficient is maintained between the packaging bags, and a greater influence is required for sliding. By optimizing the distribution of the anti-slip blocks and coating the two sides of the composite film with a lubricant, the problem of difficulty in moving the bag due to the large relative sliding friction coefficient between the film and the various formers and guide rollers of the machine during bag making is solved. Thus, the packaging bag is not easy to slip during the stacking process, and can be made smoothly to ensure production efficiency.
