GAS-BARRIER MULTILAYER FILM
First Claim
1. A gas-barrier multilayer film, comprising a plastic film and, an inorganic thin film layer and a gas-barrier resin composition layer being stacked in this order with or without intervention of other layers on at least one surface of the plastic film, whereinthe gas-barrier resin composition layer is formed from a gas-barrier resin composition comprised of a gas-barrier resin including an ethylene-vinyl alcohol-based copolymer, an inorganic layered compound, and an additive,the content of the inorganic layered compound in the gas-barrier resin composition is from 0.1% by mass to 9.0% by mass, and the additive is a coupling agent and/or a cross-linking agent, andthe thickness of the gas-barrier resin composition layer is from 0.05 μ

Abstract
Provided is a gas-barrier multilayer film which decreases little in gas-barrier properties even through retortion and which suffers no delamination. The gas-barrier multilayer film is characterized by comprising a plastic film and, superposed directly or through other layer on at least one surface thereof in the following order, an inorganic thin film layer and a gas-barrier resin composition layer. The gas-barrier film is further characterized in that the gas-barrier resin composition layer has been formed from a gas-barrier resin composition comprising a gas-barrier resin constituted of an ethylene/vinyl alcohol copolymer, an inorganic lamellar compound, and an additive, that the content of the inorganic lamellar compound in the gas-barrier resin composition is 0.1-9.0 mass %, that the additive is a coupling agent and/or a crosslinking agent, and that the gas-barrier resin composition layer has a thickness of 0.05-0.5 μm.
