| 摘要 |
<p>The present invention relates to (1) a laminate film where, on at least one face of a substrate layer (the A layer) selected from polyester film and aliphatic polyamide film, there is provided a polyamide layer (the C layer) in which the chief component is an aromatic polyamide of glass transition temperature at least 60 DEG C, as a layer to undergo vapour deposition, and the centre-line average roughness (Ra) of the face which is to undergo vapour deposition is in the range 0.005 to 0.03 mu m, or (2) a laminate film where, on at least one face a substrate layer (the A layer) selected from polyester film and aliphatic polyamide film, there is provided a polyamide layer (the C layer) in which the chief component is an aromatic polyamide of glass. transition temperature at least 60 DEG C, as a layer to undergo vapour deposition and, between the substrate A layer and the polyamide C layer, a layer (the B 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 vapour-deposition which is outstanding in its processability in vapour-deposition, and in its gas barrier properties.</p> |
