Abstract: An olefin resin-based article having good gas barrier properties is disclosed, comprising an .alpha.,.beta.-ethylenically unsaturated carboxylic acid-grafted polyolefin (e.g., maleic anhydride-grafted polypropylene) having formed thereon an inorganic oxide deposite film, wherein the grafted polyolefin has an unsaturated carboxylic acid unit concentration of from 0.01 to 10% by weight, with or without an anchor coat being provided between the grafted polyolefin and the inorganic oxide film. The article suffers from no reduction in gas barrier properties even when heat or stress is applied thereto and is therefore useful as a wrapping or packaging material in the production of pouch-packed foods and IC packages.
