  • Polymeric films
    Patent number: 5773136
    Abstract: Multilayer polymeric film comprising a base layer of a propylene polymer, a non-voided intermediate layer on the base layer, and a heat sealable polymer layer on the intermediate layer, the non-voided intermediate layer having an internal cohesive strength less than the bond strength of the intermediate layer to either the base layer or the heat sealable layer and less than the internal cohesive strengths of either the base layer or the heat sealable layer. Such films enable peelable heat seals to be formed by rupture of the intermediate layer due to its lower internal cohesive strength compared with the core layer or the heat seal layer.
