BIAXIALLY STRETCHED POLYAMIDE RESIN FILM |
| 摘要 |
The invention provides a biaxially stretched multilayer polyamide resin film having 8 or more layers in total and using a same resin composition for 80% based on the ratio of the number of the layers. The film is stretched 2.5 to 5.0 times in the longitudinal direction of the film and has an in-plane orientation coefficient (ΔP) of 0.057 to 0.07 and a strain of 0.1 to 2.0% after boiling treatment. |
