Method for producing a polyamide film coated with vinylidene chloride copolymer mixture

摘要

Disclosed is a polyamide film coated with a vinylidene chloride copolymer mixture, wherein: on at least one side of a biaxially stretched polyamide film, a vinylidene chloride copolymer mixture layer in which no thermal crosslinking agent is copolymerized is formed by coating without through an intermediary of a primer layer; the vinylidene chloride copolymer mixture is a mixture including two or more vinylidene chloride copolymers; and one of the vinylidene chloride copolymers has a crystal melting point of 170°C or higher and 210°C or lower and is contained in an amount of 25 to 45 parts by mass in relation to 100 parts by mass of the vinylidene chloride copolymer mixture.
