Abstract: A gas barrier film comprises a thermoplastic resin substrate and on the substrate a gas barrier coating, which coating comprises a water soluble or water dispersible high polymer and inorganic stratified particles. In one film, the surface of the gas barrier coating remote from the substrate has a roughness parameter Rt/Ra of 25 or less. In an alternative film, the gas barrier coating contains an amine compound represented by the following general formula: where R1 stands for a hydrogen atom, or a C1-6 alkyl or allyl or phenyl group; R2 stands for a hydrogen atom, or an optionally substituted alkyl or allyÜ group; and R3 stands for an optionally substituted alkyl or allyl group.

Abstract: PROBLEM TO BE SOLVED: To provide a thermoplastic resin film having excellent flatness, reduced in thickness irregularity and having high melt specific resistance, in particular the thermoplastic resin film suitable for a liquid crystal display element. SOLUTION: In the method for manufacturing the thermoplastic resin film by closely applying a molten sheet comprising a thermoplastic resin A with a melt specific resistance of 1×10 Ωcm or more to a cooling drum to form a film, the molten sheet, wherein a thermoplastic resin B with a melt specific resistance of Ωcm is laminated on both surfaces of the thermoplastic resin A and the end part of the sheet comprises only the thermoplastic resin B, is closely brought into contact with the cooling drum by the application of static electricity to obtain a laminated sheet and the thermoplastic resin B is removed from the laminated sheet to manufacture the thermoplastic resin film comprising the thermoplastic resin A.

Abstract: PROBLEM TO BE SOLVED: To provide a gas barrier film holding gas barrier properties, close adhesiveness and transparency under high humidity. SOLUTION: In a film wherein a coating film containing inorg. plate-shaped particles and a water-soluble polymer as main constituents is formed on at least the single surface of a thermoplastic resin base material, a gas barrier film wherein the viscosity of the water-soluble polymer in an aq. dispersion with a solid concn. of 10 wt.% is 2000 cPs or less is formed. The obtained film is excellent not only in gas barrier properties but also in close adhesiveness and transparency and can be used as a packing material.
