[Sovereign Items] 1. A method of producing a packaging laminate material for producing at least one sheet-like laminate material for a packaging container, the laminate material consisting of a base layer and a layer of heat-sealable material. Forming an inner layer, the method comprising the steps of: heating metal silver to form a silver vapor atmosphere; simultaneously or continuously introducing the oxygen-containing gas into the silver vapor atmosphere, feeding the strip-shaped base film into the silver vapor atmosphere continuously or intermittently; A layer of metallic silver film is formed on the surface of the strip-shaped base film; at the same time or afterwards, oxygen is used to oxidize part/all of the metallic silver to silver oxide to convert it into a silver oxide film; The strip base film is pulled out from an atmosphere of silver vapor containing an oxygen-containing gas to obtain a strip-shaped base layer; the inner surface of the strip-shaped base layer is laminated with a layer of heat-sealable inner layer; in the strip-shaped base layer The outer surface indirectly or directly prints the container design pattern; at the same time or successively on the outer surface and the inner surface of the strip-shaped base layer, a homogenous or a different kind and a single or multi-layer thermoplastic layer and/or a supporting layer are formed.

【International Publication】 2004-11-04 WO2004/094138 【Abstracts】 A method for producing a sheet-like laminated material for a packaging container consisting of a base layer and a heat-sealable inner layer The method includes the following steps: introducing an oxygen-containing gas in a silver vapor atmosphere; feeding a strip-shaped base film into a silver vapor atmosphere to form a layer of a metallic silver thin film on one surface of the strip-shaped base film; and Oxidation to a silver oxide film; a base film with a silver oxide film is pulled from a silver vapor atmosphere to obtain a strip-shaped base layer; and the inner surface of the strip-shaped base layer is laminated with a heat-sealable inner layer. The outer surface of the strip-like base layer prints the container design pattern; a thermoplastic layer or a support layer is formed on the outer surface and the inner surface of the strip-shaped base layer. The sealed area and its adjacent area and the entire container can be formed in an antibacterial atmosphere or with an antibacterial material.
