<p><P>PROBLEM TO BE SOLVED: To provide a resin composition which is excellent in barrier properties, mechanical strengths, flexibility, stretchability, melt stability, scrap recoverability, thermal adhesiveness, coatability, stain resistance, transparency and the like, comprises an ethylene-vinyl alcohol copolymer and a thermoplastic resin whose solubility parameter (calculated from Fedors' equation) is not more than 11, and is good in compatibility. <P>SOLUTION: The resin composition comprises (A) an ethylene-vinyl alcohol copolymer, (B) a polyamide resin, (C) an ethylene-unsaturated carboxylic acid random copolymer or its metal salt, and (D) another thermoplastic resin. The compounding weight ratios satisfy the following formulae (1)-(4): (1): 0.6≤(A+D)/(T)≤0.995; (2): 0.005≤(B+C)/(T)≤0.4; (3): 0.01≤(A)/(A+D)≤0.99 and (4): 0.02≤(B)/(B+C)≤0.98. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
