WATER-REPELLANT AND GAS BARRIER COMPOSITE MATERIAL

摘要

A water-repellant and gas barrier composite material includes a core portion and a face member mounted to one of the surfaces of the core portion. The core portion has a wood fiber based geometrically patterned structure defining two spaced-apart substantially planar surfaces and including an hydrophobic additive. The face member has a wood fiber based linerboard including an hydrophobic additive and a nylon coating film on a surface of the wood fiber based linerboard.
