Gas-tight laminate useful as a packaging material comprises adhesive layers of compatible copolymer between a barrier layer of liquid-crystalline polymer and protective layers of polyolefin

摘要

Gas-tight laminate comprising a barrier layer of liquid-crystalline polymer between protective layers of polyolefin comprises adhesive layers comprising a block or graft copolymer with a liquid-crystalline component and a polyolefin component between the barrier layer and the protective layers. An independent claim is also included for an adhesive comprising a copolymer that adheres both to a liquid-crystalline polymer film and to a polyolefin film and is a block or graft copolymer with a liquid-crystalline polymer component and a polyolefin component.
