ABSTRACT:
A process for producing oriented films and laminates of nylon 66 and of blends of nylon 66 with nylon 6. In the process, moisture is excluded from the nylon preferably by coextruding a nylon layer between layers of polymeric material to form a laminate; and, after quenching the laminate, orientation may be performed after a relatively long time lapse.
