AI Technical Summary

Technical Problem

Existing polypropylene packaging bags are prone to aging and bacterial growth, and pose a high risk of pathogen transmission during transportation, affecting health and safety performance.

Method used

The polyolefin packaging bag with a composite layer structure includes a base layer, a surface layer, and an inner layer. The base layer is composed of polyolefin, rare earth antioxidant, ultraviolet absorber, phosphogypsum whiskers, nano diatomaceous earth, dispersant, silane coupling agent, antibacterial agent, etc., and is made by a three-layer co-extrusion blow molding process. The surface layer is coated with waterproof material and release film to enhance its antioxidant, antibacterial, moisture-proof and scratch-resistant properties.

Benefits of technology

It improves the antioxidant properties of packaging bags, reduces the risk of germ transmission, enhances mechanical properties and protective capabilities, and ensures hygiene and safety during transportation.
