Abstract:
A label for a glass bottle, 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, said base layer having a 1% secant modulus of at least 200,000 psi as measured by ASTM D882, said base layer being graphically printed on via a conventional printing operation; andb) an adhesive layer bonded to said base layer, said adhesive layer consisting essentially of an adhesive having a melting point between 150.degree. F. and 220.degree. F. and having a melt index of at least 2 grams/10 minutes at 190.degree. C.; said adhesive layer being sufficiently nontacky at room temperature such that the multilayer film does not exhibit significant 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.
