Abstract

In resin composition pellets containing a desiccant, an object of the present invention is to be able to avoid bridging phenomena and stabilize the feed rate, which is to say, to improve feed stability. Provided is a resin composition pellet containing a thermoplastic resin and a desiccant and having an elliptic cylindrical shape, wherein the ratio of the short diameter b to the long diameter a of the ellipsoidal face S of the pellet P (short diameter b/long diameter a) is 0.5 to 0.9.

Claims (17)

1. A resin composition pellet containing a thermoplastic resin and a desiccant and having an elliptic cylindrical shape,

wherein the ratio of the short diameter to the long diameter of the ellipsoidal face of the pellet (short diameter/long diameter) is from 0.5 to 0.9.

2. The resin composition pellet according to claim 1 , wherein the content of the desiccant is 1 to 40 wt %, with respect to the thermoplastic resin.

3. The resin composition pellet according to claim 1 , wherein the ratio of the long diameter of the ellipsoidal face of the pellet to the length of the pellet (long diameter/length) is 0.2 to 2.

4. The resin composition pellet according to claim 1 , wherein the thermoplastic resin contains at least one member selected from the group consisting of a polyamide-based resin, a polyolefin-based resin, a polyester-based resin, a polystyrene-based resin, and a saponified ethylene-vinyl ester-based copolymer.

5. The resin composition pellet according to claim 1 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.

6. The resin composition pellet according to claim 2 , wherein the ratio of the long diameter of the ellipsoidal face of the pellet to the length of the pellet (long diameter/length) is 0.2 to 2.

7. The resin composition pellet according to claim 2 , wherein the thermoplastic resin contains at least one member selected from the group consisting of a polyamide-based resin, a polyolefin-based resin, a polyester-based resin, a polystyrene-based resin, and a saponified ethylene-vinyl ester-based copolymer.

8. The resin composition pellet according to claim 3 , wherein the thermoplastic resin contains at least one member selected from the group consisting of a polyamide-based resin, a polyolefin-based resin, a polyester-based resin, a polystyrene-based resin, and a saponified ethylene-vinyl ester-based copolymer.

9. The resin composition pellet according to claim 6 , wherein the thermoplastic resin contains at least one member selected from the group consisting of a polyamide-based resin, a polyolefin-based resin, a polyester-based resin, a polystyrene-based resin, and a saponified ethylene-vinyl ester-based copolymer.

10. The resin composition pellet according to claim 2 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.

11. The resin composition pellet according to claim 3 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.

12. The resin composition pellet according to claim 4 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.

13. The resin composition pellet according to claim 6 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.

14. The resin composition pellet according to claim 7 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.

15. The resin composition pellet according to claim 8 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.

16. The resin composition pellet according to claim 9 , wherein the thermoplastic resin contains a saponified ethylene-vinyl ester-based copolymer.
