Abstract: Abstract of the Disclosure A process is disclosed for the manufacture of a laminate of thermoplastic films in which at least one sur-face of a film selected from the group consisting of films of polyethylene, polyamide, and polyester, and such films coated with polyvinylidene chloride, is laminated to a surface of a film preferably containing an adhesion promoter such as fumaric acid and selected from the group consisting of films of polyethylene and ionomer, and such films coated with  polyvinylidene chloride, at least the surfaces of the films that are laminated having been treated with a corona discharge.  The process comprises the steps of (a) bringing the corona discharge-treated surface of one film into face-to-face contact with the corona discharge-treated surface of a second film and contacting the resultant combination of films with at least one roll heated to a temperature greater than the temperature required to form a laminate of low peel strength but less than the temperature at which the laminate adheres to the heated roll, (b) increasing the peel strength of the laminate by passing the laminate through a heated zone, the heated zone being at a temperature at least as high as, and preferably higher than,that of the heat roll, and (c) cooling the laminate so formed.  The laminates formed by the process are useful for many end uses e.g. for meat wraps and for pouches for motor oil.
