Laminated material and paper pack container formed from said material

摘要

The present invention provides a laminated material comprising a paper as a substrate, which is superior in heat resistance and gas barrier properties, and a paper pack container formed from said laminated material. Disclosed is a laminated material comprising at least a paper layer as a substrate and a layer of a liquid crystal polyester resin composition containing 56 to 99% by weight of a liquid crystal polyester (A) and 44 to 1% by weight of an epoxy group-containing ethylene copolymer consisting of the following components: (a) 50 to 99.9% by weight of an ethylene unit; (b) 0.1 to 30% by weight of an unsaturated carboxylic acid glycidyl ester unit or an unsaturated glycidyl ether unit; and (c) 0 to 49.9% by weight of an ethylenically unsaturated ester compound, the paper layer and the layer of the liquid polyester resin composition being laminated to each other. A paper pack container formed from said laminated material is also disclosed.
