Abstract: Provided is a method for producing gas barrier film, in which the coating film produced has excellent, oxygen gas barrier properties and is influenced little by moisture. The method comprises extruding a polyvinyl alcohol which contains not more than 19 mol % of &agr;-olefin units with not more than 4 carbon atoms, onto a substrate film, then stretching it at least 3-fold and subjecting it to heat treatment at a temperature not lower than 120° C.

Abstract: A water-soluble polyvinyl alcohol coating agent for a film contains from 3 to 19 mol % of &agr;-olefin units, wherein each said &agr;-olefin unit contains up to 4 carbon atoms. The polyvinyl alcohol coating agent can be coated on a polyolefin, a polyester or a polyamide substrate film to form a laminate film. A method for producing the laminate film comprises applying an aqueous solution of the coating agent to the substrate film, followed by drying the coating.

Abstract: A method of producing curved slide fastener chains or a curved slide fasteners is disclosed. Fastener elements are planted along respective one side edges of a pair of fastener tapes, at least one of which tapes is made of solvent-swelling fibers. The fastener elements planted on the respective tapes are inter-engaged with each other to form a fastener chain. A solvent or its aqueous solution, or a solution containing a solvent and dissolving a soluble adhesive, is applied onto either one of the fastener tapes made of solvent-swelling fibers. Subsequently, the fastener chain is shaped into a desired curved configuration. The shaped fastener chain has its curved configuration fixed by being served on a texture, by solidification of the adhesive dissolved in the solvent after evaporation of the solvent or by applying an adhesive onto the shaped fastener chain and solidifying the adhesive.
