Method for reducing the occurrence of polymer strands on container ends

摘要

A method to inhibit the formation of polymer strands on the edge of end panels and on the edge of spouts in container ends coated with thermoplastic polymers. The ends are heated sufficiently to induce crystallite formation in the thermoplastic polymer coating. Heating renders the coating less ductile, more brittle, less elastic and less prone to feathering and angel hair formation upon opening of container tabs.
