RESIN COMPOSITION, MOLDED BODY, LAMINATE, THERMOFORMED CONTAINER, BLOW-MOLDED CONTAINER, FILM, AGRICULTURAL FILM, PLANT MEDIUM, AND PIPE
Document Type and Number:
WIPO Patent Application WO/2021/166276
Kind Code:
A1
Abstract:
Provided is a resin composition from which a molded body can be obtained that is suppressed from the occurrence of spots during melt-molding, has sufficient heat and light resistance, and is less likely to microplasticized after disposal. The aforesaid properties of this resin composition are sufficiently improved when compared with those using the same ethylene-vinyl alcohol (EVOH) copolymer. The resin composition contains an EVOH (A) and aluminum ions(B), wherein: at least a portion of the EVOH (A) has at least one among a carboxylic acid unit (I) and a lactone ring unit (II) located at the end of a polymer; the total content (i+ii) of the carboxylic acid unit (I) and the lactone ring unit (II) per 1 g of the EVOH (A) is 14 μmol/g to 78 μmol/g; and the content (b) of the aluminum ion (B) per 1 g of the EVOH (A) is 0.002 μmol/g to 0.17 μmol/g.
