Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A biaxially stretched multilayer polyamide resin film having 8 or more layers in total, wherein 80% or more of the layers comprise the same resin composition, the film contains 0.3 to 10 wt. % of an inorganic material containing a layered compound, the film is stretched 2.5 to 5.0 times in the longitudinal direction of the film and the film has an in-plane orientation coefficient (AP) of 0.057 to 0.07 and a strain of 0.1 to 2.0% after boiling treatment. 2. The biaxially stretched multilayer polyamide resin film as described in claim 1 , wherein at least one layer or more of resin layers containing a polyamide resin having a meta-xylylene skeleton as a main component are laminated. 3. The biaxially stretched multilayer polyamide resin film as described in claim 1 , wherein the layered compound is in-plane oriented, and the oxygen permeation amount in conversion into 15 pm is 0.05 to 18 cc. 4. The biaxially stretched multilayer polyamide resin film as described in claim 3 , wherein at least one layer or more of resin layers containing a polyamide resin having a meta-xylylene skeleton as a main component are laminated.
