| 摘要 |
The present invention relates to a laminate film where on at least one face of a substrate layer selected from polyester film and aliphatic polyamide film, there is provided a polyamide layer in which the chief component is an aromatic polyamide of glass transition temperature at least 60° C., as a layer to undergo vapor deposition, and (1) the center-line average roughness (Ra) of the face which is to undergo vapor deposition is in the range 0.005 to 0.03 mum, or (2) between the substrate layer and the polyamide layer, a layer comprising a single polymer or a plurality of polymers of SP value 10 to 15 is interposed between the substrate A layer and the polyamide C layer; and the invention offers film for vapor-deposition which is outstanding in its processability in vapour-deposition, and in its gas barrier properties.
