DRAWN FILM CONTAINING MODIFIED VINYL ALCOHOLIC POLYMER, AND LAMINATE, AND METHOD FOR PRODUCING THEM

Document Type and Number:

Japanese Patent JP2022120387

Kind Code:

A

Abstract:

To provide a drawn film that has excellent stretchability and also has excellent oxygen gas barrier properties at high humidity after stretched.SOLUTION: A drawn film contains a modified vinyl alcoholic polymer, wherein the polymer is represented by the formula (I). Relative to all the monomer units, the content of each monomer unit, a (mol%), b (mol%) and c (mol%), satisfies the formulae (1)-(3): 4≤a≤20 (1), 0.8≤c≤20 (2) and [100-(a+c)]×0.9≤b≤[100-(a+c)] (3).SELECTED DRAWING: None
