Abstract
Food packaging-use formed articles including at least one layer of a 3 to 90 microns thickness which comprises a composition consisting of polyvinyl alcohol resin having a degree of saponification of 60 to 95 mole % (A) and a compound elected from a group of alkylene glycol polymer, etc. falling within the range of from 3 weight parts of (B) to 100 weight parts of (A) to the saturated solubility of (B) in (A) and having a carbon dioxide/oxygen solubility ratio (SCO.sub.2 /SO.sub.2) of 30 or higher. Furthermore, a resin composition consisting of the aforementioned (A), (B) and a saponified ethylene/vinylacetate copolymer resin (C) wherein the blending ratio of (B) is within the range of from 3 weight parts of (B) to 100 weight parts of (A) to the saturated solubility of (B) in (A), and the blending ratio of (C) being 20 to 50 weight parts of (C) to 100 weight parts of an aggregate of (A) and (C), and food packaging-use melt extruded articles containing at least one layer comprising the aforementioned composition.
