POLYMER FILM |
| 摘要 |
There is provided a polymer film which includes: a base film layer including a polyamide-based resin having a particular relative viscosity and a copolymer including a polyamide-based segment and a polyether-based segment having a specific content; and an adhesive layer formed on at least one side of the base film layer, wherein a ratio of the melt viscosity of the copolymer to the melt viscosity of the polyamide resin is 0.65 to 1.2 at a shear rate of 1000 s−1 and a temperature of 260° C. |

1. A polymer film which comprises:
a base film layer comprising a polyamide-based resin having a relative viscosity (96% sulfuric acid solution) of 3.0 to 3.5 and a copolymer comprising a polyamide-based segment and a polyether-based segment; and an adhesive layer formed on at least one side of the base film layer and containing resorcinol-formalin-latex (RFL)-based adhesive, wherein a content of the polyether-based segment of the copolymer is more than 2% by weight and less than 15% by weight with respect to the total weight of the base film layer, and wherein a ratio of a melt viscosity of the copolymer to a melt viscosity of the polyamide resin is 0.60 to 1.2 at a shear rate of 1000 s−1 and a temperature of 260° C. |
