AI Technical Summary
Traditional aluminum foil easy-tear caps are prone to film delamination, leakage, and reduced strength under high-temperature cooking conditions, affecting the protection and sealing of the contents. In addition, the heat resistance of the nylon film layer is insufficient.
The structure consists of a protective layer, a first reinforcing layer, an aluminum foil layer, a second reinforcing layer, and a heat-sealing layer. Stability is improved by using modified polyvinyl alcohol and composite reinforcing materials, and combined with adhesive bonding technology to form a multi-layer aluminum foil easy-tear cover.
It improves the stability and high-temperature resistance of aluminum foil easy-tear caps, prevents damage and delamination, extends service life, and enhances the sealing and protection of packaging.
