Claims
- 1. A resin composition consisting essentially of 60 to 95 wt. % of a saponified product of an ethylene-vinyl acetate copolymer (A) having an ethylene content of 25 to 50 mol %, a saponification degree of vinyl acetate component of at least 90%, and a melt index at 190.degree. C. -2160 g (MI) of not more than 15 g/10 min and 40 to 5 wt % of a partially saponified product of an ethylene-vinyl acetate copolymer (B) having an ethylene content of 82 to 94 mol %, a saponification degree of vinyl acetate component of 20 to 98%; the MI's and the vinyl alcohol contents of resin (A) and resin (B) and the blending ratio of resin (B) in said composition giving P-value obtained from the following formula (1) of not more than 40: ##EQU2## where: M=M.sub.A /M.sub.B (when M.sub.A .gtoreq.M.sub.B)
- M=M.sub.B /M.sub.A (when M.sub.A <M.sub.B)
- M.sub.A : MI of resin A
- M.sub.B : MI of resin B
- VA.sub.A : content of vinyl alcohol component of resin A (mol %)
- VA.sub.B : content of vinyl alcohol component of resin B (mol %)
- B: wt % of resin B blended in the composition.
- 2. A resin composition as defined in claim 1, wherein said P-value obtained from formula (1) is not more than 15.
- 3. A resin composition as defined in claim 1 or claim 2, wherein said saponified product of ethylene-vinyl acetate copolymer (A) has an MI of not more than 7 g/10 min.
- 4. A resin composition as defined in claim 1, wherein said saponified product of an ethylene-vinyl acetate copolymer (B) has a saponification degree of vinyl acetate component of 30 to 98.
- 5. A multilayered structure comprising at least one layer made of the resin composition of claim 1.
- 6. A resin composition as defined in claim 1, wherein said saponified product of an ethylene-vinyl acetate copolymer (A) has an ethylene content of 84 to 94 mol %.
- 7. A resin composition according to claim 1, additionally including an additive selected from the group consisting of plasticizers, heat stabilizers, antioxidants and colorants.
- 8. A resin composition according to claim 7, wherein the additive is a plasticizer.
- 9. A resin composition according to claim 8, wherein the plasticizer is selected from the group consisting of glycerine, diglycerine, 1,2-propanediol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, 1,2,6-hexanetriol, diethanolamine and diethylene glycol, dimethylphthalate, diethyl phthalate, dioctyl phthalate, wax, liquid paraffin, phosphoric acid esters and amides.
