Abstract

A multi-layer film structure suitable as a sealable sheet used for closing foodstuff containers with a peelable seal. This multi-layer film comprises a polyester substrate layer and a heat-sealable layer. The heat-sealable layer is applied by coextrusion and contains an epoxy-containing thermoplastic polymer composition comprising residues of epoxy-containing monomers selected from glycidyl methacrylate, glycidyl acrylate, allyl glycidyl ether, 3,4-epoxy-1-butene, and a mixture of any two or more of such monomers.
