AI Technical Summary

Benefits of technology

This new technology improves resistance for static electricity by adding two layers - one inside another outside the other's surface that helps keep out any electrical charges or particles during use. It also includes an antistatic coat made up of polyethyleneglycol (PEG) plastic mixed into water beforehand at high pressure. To make this mixture easier to apply onto both surfaces, there may be added some type of rubber material between them. Overall, these technical improvements enhance its performance over existing methods while maintaining their benefits compared to previous designs.

Problems solved by technology

The technical problem addressed by this patented package design relates to its lack of strength or durability for repeated uses due to damage caused from external forces such as bending during shipping and handling processes. This can lead to leakage of harmful substances into sensitive products stored therein causing them discomfort when consumed with these materials over time.

Abstract

The invention discloses an antistatic shielding aluminum-plastic composite packaging material. The antistatic shielding aluminum-plastic composite packaging material is provided with an outer protective layer, an outer adhesive layer, an antistatic coating, an aluminum foil layer, an outer adhesive layer A, a nylon film, an outer adhesive layer B and a heat seal layer which are sequentially arranged from the outside to the inside. The antistatic coating is prepared from, by weight, 42-55 parts of synthetic acrylic resin, 50-60 parts of epoxy resin, 20-35 parts of diatomaceous earth, 20-28 parts of graphite with the purity being 99% or over, 0.5-1.3 parts of a dispersing agent, 2-4 parts of a defoaming agent, and 3-5 parts of thickener. With additional arrangement of the antistatic coating,double-layer anti-static measures can improve the capacity of anti-static shielding; a foaming machine is used for foaming, and obtained composite foaming slurry coats the anti-static coating as a protective layer, and can well buffer impact and puncture from the outside; and the nylon film on the inner side can avoid damage to the aluminum foil layer caused by objects on the inner side.
