摘要: Thermoplastic films particularly suited for use in bags including at least a core layer comprising an ethylene copolymer, wherein the films are subjected to post-quench biaxial orientation are provided. Optionally, the films may have a first skin layer and/or a second skin layer located on each side of the core layer. Embodiments may have the desirable combination of improved puncture toughness and ultimate tensile strength, low manufacturing cost and desirable optical and tactile properties.

摘要: The invention concerns a certain class of polymers, their production into films and applications for their use. These polymers have unique properties which make them particularly well suited for use in polymeric films. These films are very useful in applications requiring heat sealability, particularly those applications containing an ionomer film.It has been discovered that polymers derived from metallocene catalyst systems surprisingly heat seal extremely well, as compared to polymer produced by conventional Ziegler-Natta catalysts, to a class of polymers known as ionomers.
