ABSTRACT:
A process for the heat lamination of a first film of polyethylene, polyamide, polyester, and such films coated with polyvinylidene chloride, to a second film of polyethylene, ionomer, and such films coated with polyvinylidene chloride. The surface of the first and second films has been treated with a corona discharge prior to heat lamination, and preferably the second film has an adhesion promoter on its surface. The process has the steps of (a) bringing the first and second films into contact, (b) contacting the combined films with a roll heated to a temperature greater than that required to produce low peel strength but less than that at which the laminate adheres to it, (c) passing the laminate through a heated zone to increase the peel strength, and (d) cooling the laminate.
