ABSTRACT:
The present invention relates to peelable resealable multilayer films which include at least a first polymer layer, a second polymer layer of pressure-sensitive adhesive in direct contact with and bonded to both the first and third layers. The bond formed between the second and third layers includes a peelable resealable interface having a first interfacial peel strength, A, and a second interfacial peel strength, B. The peelable resealable interface includes a first interfacial peel strength, A, having a value of less than 3500 gram-force/inch (1350 newton/meter) as measured in accordance with ASTM F-904-98 test method when the films of the present invention are peeled from a second thermoplastic film to which the film has been heat-sealed. The second interfacial peel strength, B, has a value of at least 400 gram-force/inch (154 newton/meter) as measured in accordance with ASTM F-904-98 test method when the films are peeled from and re-adhered to a second film.
