Claims24
A resin composition (X) comprising an ethylene-vinyl acetate copolymer (A), wherein the ethylene-vinyl acetate copolymer (A) contains carbon-14.
A resin composition (X) comprising:
- an ethylene-vinyl acetate copolymer (A);
- and
- a saponified ethylene-vinyl acetate copolymer (B) having an ethylene content of greater than 60 mol %,
- wherein the ethylene-vinyl acetate copolymer (A) and/or the saponified ethylene-vinyl acetate copolymer (B) contain carbon-14.
A resin composition (Y) comprising:
- an ethylene-vinyl acetate copolymer (A);
- a polyolefin resin (C);
- and
- an ethylene-vinyl alcohol copolymer (D),
- wherein the ethylene-vinyl acetate copolymer (A) contains carbon-14.
A resin composition (Y) comprising:
- an ethylene-vinyl acetate copolymer (A);
- a saponified ethylene-vinyl acetate copolymer (B) having an ethylene content of greater than 60 mol %;
- a polyolefin resin (C);
- and
- an ethylene-vinyl alcohol copolymer (D),
- wherein the ethylene-vinyl acetate copolymer (A) and/or the saponified ethylene-vinyl acetate copolymer (B) contains carbon-14.
A method for producing a recycling agent, the method comprising mixing an ethylene-vinyl acetate copolymer (A) and a saponified ethylene-vinyl acetate copolymer (B) having an ethylene content of greater than 60 mol %,
- wherein the ethylene-vinyl acetate copolymer (A) and/or the saponified ethylene-vinyl acetate copolymer (B) contains carbon-14.
A method for producing a regrind layer by forming a resin composition, the method comprising mixing a polyolefin resin (C), an ethylene-vinyl alcohol copolymer (D), an ethylene-vinyl acetate copolymer (A), and a saponified ethylene-vinyl acetate copolymer (B) having an ethylene content of greater than 60 mol %,
- wherein the resin composition contains the ethylene-vinyl acetate copolymer (A) and/or the saponified ethylene-vinyl acetate copolymer (B) containing carbon-14.
