Polyvinyl alcohol type resin, monolayer film and laminate |
摘要 |
A polyvinyl alcohol type resin, which renders possible preparation of a packaging material having high gas barrier property under a high humidity condition even as a monolayer film, is provided. The polyvinyl alcohol (PVA) type resin of the invention has at least a PVA structural unit and also has an alicyclic structural unit in the main chain. A monolayer film containing this PVA type resin and a laminate containing at least one layer comprising this PVA type resin can be used as a packaging material which shows high gas barrier property even under a high humidity condition. |
