METHOD FOR PRODUCING GAS BARRIER MULTILAYER BODY |
摘要 |
<p>A method for producing a gas barrier multilayer body is disclosed which comprises formation of a multilayer body and heat-treating of the obtained multilayer body in the presence of water. The multilayer body includes a plastic base, a gas barrier layer made of a gas barrier layer-forming coating material which contains polyvinyl alcohol and ethylene-maleic acid copolymer, and a polymer layer containing a metal compound of a divalent or higher multivalent metal, and the polymer layer is put on top of at least one surface of the gas barrier layer. It is also disclosed a method for producing a gas barrier multilayer body which comprises heat-treating of a plastic base onto which a gas barrier layer-forming coating material containing polyvinyl alcohol and ethylene-maleic acid copolymer is applied directly or via an undercoat layer, and heat-treating of the thus-obtained multilayer body in the presence of water containing a metal compound of a divalent or higher multivalent metal.</p> |
