PURPOSE:To obtain a gas-barrier resin compsn. having high gas and water vapor barrier properties or a film made from the compsn. by compounding a specific inorg. layered compd. with a resin. CONSTITUTION:A gas-barrier resin compsn. is prepd. by compounding an inorg. layered compd. which has a particle size of 5mum or lower and an aspect ratio of 50-5,000, swells and cleaves in a solvent, and pref. is a swellable clay mineral (e.g. a synthetic tetrasilylic fluoromica) with a resin which is pref. a resin exhibiting strong hydrogen bonding, still pref. PVA or a polysaccharide, in a vol. ratio of the compd. to the resin of (5:95)-(90:10). |
