Abstract:
A multilayer film, comprising:a) A base layer, said base layer having a maximum shrinkage at 250.degree. F. of less than about 2% in the machine direction and less than about 2% in the transverse direction; andb) An adhesive layer bonded to said base layer, said adhesive layer consisting of at least one resin selected from the group consisting of 1) terpolymers of ethylene, about 1 to 30% by weight of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid comonomer, and about 1 to 40% by weight of either a vinyl ester or an allyl ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid; 2) terpolymers of ethylene, 1-30% by weight of either a vinyl ester or an alkyl ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, and 1-4% maleic anhydride; and 3) organosilane-modified ethylene copolymers and terpolymers, the adhesive layer being sufficiently nontacky at room temperature such that the multilayer film does not exhibit blocking at room temperature, and wherein the multilayer film, upon contacting said adhesive layer to a glass substrate heated to greater than about 200.degree. F. and thereafter cooling, exhibits a dry adhesion peel strength of at least about 750 grams/inch and a wet adhesion peel strength of at least about 450 grams/inch.
