Abstract:
1. A resin composition comprising from 50 to 95% by weight of a modified ethylene-vinyl alcohol copolymer (C) that contains from 0.3 to 40 mol % of a structural unit (I) provided below and has an ethylene content of from 5 to 55 mol %, and from 5 to 50% by weight of a resin (F) that is a styrene-diene block copolymer, a hydrogenated product thereof, or an olefin-based copolymer, and that has at least one functional group able to react with a hydroxyl group and has a Young's modulus at 23° C., 50% RH of 500 MPa or less, wherein the resin (F) is dispersed with an average particle diameter of 0.1 μm or less in a matrix of the modified ethylene-vinyl alcohol copolymer (C), and wherein the resin composition has an oxygen transmission rate at 20° C., 65% RH of not more than 100 cc·20 μm/m 2 ·day·atm,: wherein R 1 , R 2 , R 3 and R 4 denote a hydrogen atom, an aliphatic hydrocarbon group having 1 to 10 carbon atoms, an alicyclic hydrocarbon group having 3 to 10 carbon atoms or an aromatic hydrocarbon group having 6 to 10 carbon atoms; R 1 , R 2 , R 3 and R 4 may be the same group or may differ; R 3 and R 4 may be combined together; and R 1 , R 2 , R 3 and R 4 each may have a hydroxyl group, a carboxyl group or a halogen atom.
