Abstract
The present invention relates to peelable resealable multilayer films which include at least a first thermoplastic layer of an anhydride-modified polyolefin, a second thermoplastic layer of an ethylene/vinyl alcohol copolymer and a third thermoplastic layer of a tacky pressure-sensitive adhesive. The bond formed between a second layer of ethylene/vinyl alcohol copolymer and a third layer of a tacky pressure-sensitive adhesive creates a peelable resealable interface having a first interfacial peel strength, A, and a second interfacial peel strength, B.
