<p>PROBLEM TO BE SOLVED: To heighten gas-barriering property while making recycling easy by a method wherein a resin composition layer including an inorganic laminated compound is arranged as a gas-barriering layer. SOLUTION: A coating liquid formed by dispersing a resin composition including a cleaved inorganic laminated compound into a dispersion medium is applied to a base layer 1 such as paperlike matter layer, and thereby a paint film is formed. Then, a resin composition layer 3 is formed with the dispersion medium removed, for instance by drying, from the paint film. In order to give a heat sealing property, a thermoplastic resin layer 4 is desirable to be laminated on the resin composition layer 3. For resin to be included in the coating liquid, a resin in high hydrogen bondability is desirable from the viewpoint of dispersiveness. The inorganic laminated compound is an inorganic compound wherein unitized crystal layers are laminated together to form a laminated structure, and the particle size thereof is 5μm or below when cleaved and a aspect ratio regarding the gas-barriering property is preferably 50-5,000, more preferably in a range of 200-3,000.</p> |
