RESIN COMPOSITION, MULTILAYER SHEET, PACKAGING MATERIAL AND CONTAINER |
摘要 |
Provided is a resin composition that exhibits inhibited flow marks, coloring and odor in a long-run operation, and is superior in heat stretching properties. The resin composition contains: an ethylene-vinyl alcohol copolymer (EVOH) (A) having an ethylene content of 20 mol % or greater and 50 mol % or less; EVOH (B) having an ethylene content of 30 mol % or greater and 60 mol % or less; and a saturated carbonyl compound (C) having 3 to 8 carbon atoms, wherein the saturated carbonyl compound (C) is a saturated aldehyde (C-1), a saturated ketone (C-2) 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 or greater and 95/5 or less, and 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. |

1. A resin composition, comprising:
an ethylene-vinyl alcohol copolymer (A) having an ethylene content of 20 mol % or greater and 50 mol % or less; an ethylene-vinyl alcohol copolymer (B) having an ethylene content of 30 mol % or greater and 60 mol % or less; and a saturated carbonyl compound (C) comprising from 3 to 8 carbon atoms, wherein: the saturated carbonyl compound (C) is a saturated aldehyde (C-1), a saturated ketone (C-2) or a combination thereof, a value obtained by subtracting the ethylene content of the ethylene-vinyl alcohol copolymer (A) from the ethylene content of the ethylene-vinyl alcohol copolymer (B) is 8 mol % or greater, a mass ratio (A/B) of the ethylene-vinyl alcohol copolymer (A) to the ethylene-vinyl alcohol copolymer (B) is 60/40 or greater and 95/5 or less, and a content of the saturated carbonyl compound (C) with respect to a resin content is 0.01 ppm or greater and less than 100 ppm. |
