Abstract
Provided is a laminated film which exhibits high gas barrier performance immediately after the production and has excellent adhesive strength between constitutional layers, while maintaining the excellent gas barrier performance. The laminated film has at least one constitutional unit layer on an inorganic thin film formed at least on one surface of a base film. The constitutional unit layer is composed of an anchor coat layer having a thickness of 0.1 to 10 nm and an inorganic thin film formed on the anchor coat layer. A method for producing the laminated film is also provided.
Claims11
A gas barrier laminated film, comprising an inorganic thin film formed on at least one side of a base film, wherein on that thin film there is at least one constitutional unit layer containing a 0.1 to 10 nm thick anchor coat layer, and an inorganic thin film formed on the anchor coat layer.
A method for producing a gas barrier laminated film, comprising the steps of:
- (A) forming an inorganic thin film on at least one side of a base film by a deposition method;
- and
- (B) forming at least one constitutional unit layer which is obtained by successively forming a 0.1 to 10 nm thick anchor coat layer and an inorganic thin film formed by a deposition method on the inorganic thin film.
