Patent ID: 8283010

Claim:
A peelable resealable multilayer film comprising: at least a first thermoplastic layer, a second thermoplastic layer and a third thermoplastic layer; wherein said first layer is an exterior film layer and comprises a homopolymer or copolymer selected from the group consisting of polyolefin, ionomer and blends thereof; wherein said second layer is in direct contact with and bonded to both said first and third layers; wherein said second layer comprises a tacky pressure-sensitive adhesive; wherein said third layer comprises cyclic olefin copolymer; wherein said bond between said second and third layers comprises a peelable resealable interface having a first interfacial peel strength “A” and a second interfacial peel strength “B” such that the value of A is less than 3500 gram-force/inch (1350 newton/meter) as measured in accordance with ASTM F-904 test method when peeled from a second thermoplastic film to which said film has been heat-sealed, and the value of B is at least 330 gram-force/inch (127 newton/meter) as measured in accordance with ASTM F-904 when peeled from and resealed to said second film; and wherein the relative values of A and B satisfy the relationship A≧B.
