OLEFIN RESIN MOLDING HAVING GAS-BARRIER PROPERTIES

摘要

PURPOSE:To obtain the molding being improved in adhesion to the constituent thin film and gas-barrier properties by forming a thin film of an inorganic oxide on the surface of a molding of a specified modified polyolefin. CONSTITUTION:A modified polyolefin of an MFR (JIS K 7210) of 0.01-100g/10min, obtained by grafting 0.01-10wt.% alpha,beta-ethylenically unsaturated carboxylic acid onto a polyolefin, is molded to obtain a molding of a thickness of 200mum-10mm. A thin film of an inorganic oxide of a thickness of 200-4000Angstrom is vapor-deposited on the surface of this molding.
