MICROLAYER COMPONENT FOR FILMS WITH IMPROVED GAS/MOISTURE BARRIER BY CONTROLLING CRYSTAL LAMELLAE ORIENTATION

摘要

A component in microlayer has better Barrier Properties to oxygen and water vapour (i.e., Lower permeabilities) comprises a microlayer of a semicrystalline Polymer Barrier Barrier in direct contact with a microfilm of confinement to promote the formation of Lu00e1m Inas Crystal plane.A component that has a significant amount of microlayer sheets in Crystal plane can be characterized by at least 1.5 x improves the permeability of oxygen and at least 1.5 x improves the permeability of water vapor.A component in the microlayer is at least 1.5 x improves the permeability of oxygen and water vapor can be coextruir and subject to stretching posextrusiu00f3n or heat treatment.
