Method to improve adhesion of a formed gasket to plastic closures

摘要

A method of attaching a gasket to a plastic surface includes providing a plastic material having a surface; applying sufficient heat to the surface to melt the surface while other portions of the plastic material remain solid; providing a liquid gasket material on the heated surface while the heated surface is melted; and allowing the liquid gasket material and the surface to cool so the gasket is welded to the plastic material.
