Kind Code:
A1
Abstract:
Disclosed is a resin composition comprising EVOH (A), an unmodified ethylene-α-olefin copolymer (B), an acid-modified ethylene-α-olefin copolymer (C), and an alkali metal salt (D), wherein: the mass ratio [(A)/((B)+(C))] is from 80/20 to 65/35; the mass ratio [(B)/(C)] is from 92/8 to 70/30; the MFR of (A) is from 8.0 g/10 minutes to 15 g/10 minutes inclusive; the content of (D) in terms of metal is from 25 ppm to 300 ppm inclusive; and the MFR of the resin composition is from 2.0 g/10 minutes to 4.0 g/10 minutes inclusive. By using this resin composition, it is possible to obtain a multi-layer structure and a bag-in-box inner container having excellent oxygen barrier characteristics, high flexibility, and resistance to bending.
