Patent ID: 8541073

Claim:
A multilayer structure comprising at least one adhesive layer produced from a composition, at least one second layer, and at least one third layer wherein the adhesive layer forms a peelable seal characterized by interfacial peel failure to the third layer; the composition consists essentially of (a) from about 10 to about 80 weight % of a combination of an ethylene/alkyl acrylate copolymer and an ionomer of either ethylene/acrylic acid copolymer or ethylene/methacrylic acid copolymer; (b) from about 5 to about 60 weight % of a polyolefin consisting essentially of high density polyethylene, linear low density polyethylene, very low density polyethylene, ultra low density polyethylene, low density polyethylene, or combinations of two or more thereof; (c) from 0 to about 35 weight % of at least one tackifying resin; and (d) from 0 to about 35 weight % of filler; the second layer comprises or is produced from foil, paper, polyester, polyamide, polyolefin, polyethylene vinyl alcohol, polyethylene vinyl acetate, ethylene/(meth)acrylic acid copolymer, ionomer of ethylene/(meth)acrylic acid copolymer, polyvinyl chloride, polyvinylidene chloride, or anhydride-modified polyolefin; and the third layer comprises or is produced from polypropylene, polystyrene or high-impact polystyrene, expanded polystyrene, acrylic homopolymer, acrylic copolymer, polycarbonate, polysulfone, amorphous polyethylene terephthalate, crystalline polyethylene terephthalate, PVC, polychlorotrifluoroethylene, polyacrylonitrile homopolymer, polyacrylonitrile copolymer, polyacetal, or polyacetal copolymer.
