CLAY DISPERSED POLYAMIDE AND NANOCOMPOSITE COMPOSITE POLYLACTIC RESIN MOLDED ARTICLE HAVING ENHANCED GAS BARRIER PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a PLA bottle material having improved oxygen and/or vapor gas barrier property, which can be used as a replacement of PET for beverage.SOLUTION: There is provided a film or bottle-shaped molded article obtained by extending and molding a resin for molding which is a PLA nanoalloy by uniformly dispersing a nanocomposite, where a nanosheet of a cleaved swellable clay is dispersed in PA11-based polyamide resin to a monolayer level, in a polylactic (PLA) resin, where the nanocomposite deformed by the extending and molding and the nanosheet dispersed therein are oriented in the extension direction.SELECTED DRAWING: None
