Abstract

Composite film structures for packaging use. The composite film structures have easy open, clean peel and hermetic seal characteristics stemming from good caulkability characteristics when a region of the composite film structures are folded over and sealed to form a seal on a bag, pouch or package. The composite film structure includes a base film which includes a biaxially-oriented film and a vacuum-deposited metal layer and a heat-sealant structure comprising a low density polyethylene and a linear low density polyethylene. The metal layer is between the biaxially-oriented film and the heat-sealant structure. The heat-sealant structure thickness is from about 50 to about 100 gauge, the adhesion strength between the biaxially-oriented film and the metal layer is less than about 800 g/in, and the seal strength when a region of the composite film structure is folded onto a composite film structure region is from about 500 to about 1500 g/in.
