AI Technical Summary

Technical Problem

Due to the thin structure of conventional composite membrane bags, they cannot effectively block ultraviolet rays, causing organic materials to age, fade, turn yellow, or cause damage to electronic equipment.

Method used

A transparent high-barrier composite film bag is adopted. The main body of the film bag includes a PE layer, a PMMA layer and a PTFE layer. The PMMA layer and PTFE layer provide ultraviolet barrier, temperature resistance and chemical corrosion resistance respectively. The edge seal is used to strengthen the structural support of the film bag body.

Benefits of technology

Effectively block or reduce ultraviolet rays, extend the service life of stored items, and improve the waterproof and moisture-proof performance of the membrane bag, and enhance the support capacity of the structure.
