ABSTRACT:
A method for producing a laminated material, which comprises providing a raw material roll containing a support layer, drawing out a support layer in a web form from the raw material roll, transferring a silver-based thin film layer on an inner face of the inside of the support layer including a zone to be heat-sealed by the high frequency induction heating for the formation of a container, prior to or after the transferring step, laminating a heat-sealable inner layer on the inside of the support layer, printing the design of the container on the outside of the support layer in a long web form, and forming one or more thermoplastic layers of the same type or different types, at the same time or sequentially, on the outside and the inside of the printed support layer in a web form. The method allows a sealing zone to be formed so as to have an antibacterial atmosphere.
