Abstract
The inter-layer adhesion of laminates comprised of alternating layers of thermoplastic polyester and ethylene-vinyl acetate copolymer is greatly enhanced by a method of treatment of the laminate with a stream of inert gas at elevated temperatures which is described. The treated articles in general exhibit a T-peel strength of 1 in. lb./in..sup.2 and greater, which is far in excess of the peel strengths typical of the untreated article.
