Abstract
A resin composition includes an ethylene-vinyl alcohol copolymer (EVOH) (A) having an ethylene content of 20 to 50 mol %, an EVOH (B) having an ethylene content of 30 to 60 mol %, and a saturated carbonyl compound (C) having 3 to 8 carbon. The saturated carbonyl compound (C) is a saturated aldehyde, a saturated ketone, or a combination thereof. A value obtained by subtracting the ethylene content of the EVOH (A) from the ethylene content of the EVOH (B) is 8 mol % or greater. The mass ratio (A/B) of the EVOH (A) to the EVOH (B) is 60/40 to 95/5. The content of the saturated carbonyl compound (C) with respect to the resin content is 0.01 ppm or greater and less than 100 ppm.
Claims9
A resin composition, comprising:
