Abstract
Provided are a laminated structure having a composition coping with environmental problems and having an excellent gas barrier property and oil resistance, a food packaging container formed by using the laminated structure, and a method for producing the laminated structure. The laminated structure includes a second coating layer including a polyvinylidene chloride-based resin through a first coating layer formed by blending clay in a proportion of 35% by mass or more and 65% by mass or less and light calcium carbonate in a proportion of 5% by mass or more and 30% by mass or less in a continuous phase made of an acrylic polymer on one surface or both surfaces of a substrate including a thermoplastic resin and an inorganic substance powder in a mass ratio of 50:50 to 10:90.

A laminated structure comprising:
- a second coating layer comprising a polyvinylidene chloride-based resin through a first coating layer formed by blending clay in a proportion of 35% by mass or more and 65% by mass or less and light calcium carbonate in a proportion of 5% by mass or more and 30% by mass or less in a continuous phase made of an acrylic polymer on one surface or both surfaces of a substrate comprising a thermoplastic resin and an inorganic substance powder in a mass ratio of 50:50 to 10:90.
A method for producing a laminated structure, the method comprising:
- applying an acrylic polymer aqueous emulsion containing clay in a proportion of 35% by mass or more and 65% by mass or less and light calcium carbonate in a proportion of 5% by mass or more and 30% by mass or less in a dried mass in a continuous phase of an acrylic polymer on one surface or both surfaces of a substrate including a thermoplastic resin and an inorganic substance powder in a mass ratio of 50:50 to 10:90, and thereafter applying a polyvinylidene chloride resin latex.
