Abstract: A barrier film according to the present disclosure has a base material film including a polyolefin-based resin; an inorganic oxide layer provided on one surface of the base material film; and a deformation-withstanding barrier coat layer provided on the inorganic oxide layer to be in contact therewith, wherein the deformation-withstanding barrier coat layer includes a hydroxyl group-containing polymer compound and water-swellable mica, and when the total mass of the deformation-withstanding barrier coat layer is taken as 100 parts by mass, the content of the water-swellable mica in the deformation-withstanding barrier coat layer is 5 parts by mass to 35 parts by mass.

Abstract: A method of producing a gas barrier laminate of the present disclosure includes a step of forming a coating film on a surface of a base film or a laminate including the base film, the coating film containing zinc ions, at least one of metal alkoxide and a hydrolysate thereof, and an aqueous polymer, and a step of drying the coating film to form a gas barrier layer on the surface of the base film or the laminate including the base film. A gas barrier laminate of the present disclosure includes a base film or a laminate including the base film, and a gas barrier layer provided on a surface of the base film or the laminate including the base film. In the gas barrier laminate, the gas barrier layer contains zinc dispersed in the gas barrier layer and an organic-inorganic composite.

Abstract: The present disclosure relates to a laminate film for packaging. A laminate film according to an aspect of the present disclosure includes: a resin substrate having a heat sealing surface that constitutes one outermost surface of the laminate film; a coating layer made of a non-metallic material; and an underlayer disposed between the resin substrate and the coating layer. The resin substrate includes a first layer that is made of olefin copolymer and constitutes the heat sealing surface, and a second layer made of polypropylene, and the first and second layers are laminated and biaxially stretched.

Abstract: A gas barrier film includes a first base material film made of a plastic material and a coating layer formed on one of surfaces of the first base material film, the coating layer contains a watersoluble polymer and a water-swelling mica, the solid content ratios of the water-swelling mica in 5 a total solid content of the coating layer are within approximate ranges indicated from 20 mass % to 50 mass %, the mean area diameter of the water-swelling mica is within approximate ranges indicated from 0.5 ?m to 5 ?m, and the thickness of the coating layer is within approximate ranges indicated from 0.1 ?m to 1 ?m.
