Abstract:
It is intended to provide a metal can from which the contents packed therein are easy to take out and which has been coated with a polyester resin film for food or with a film for food which is made of a resin consisting mainly of a polyester resin; a metal sheet which has been coated with a surface-roughened resin film and is for use in the metal can; a surface-roughened resin film for use in the metal sheet; and processes for producing these. The surface-roughened resin film is one which comprises a polyester resin and, incorporated therein, either inorganic particles or a resin incompatible with the polyester resin, e.g., a polyolefin resin, to thereby have a roughened surface. Alternatively, the surface-roughened resin film is one obtained by embossing a surface of a resin film. The surface-roughened resin film is laminated to a metal sheet. Alternatively, a resin film which has not undergone surface roughening is laminated to a metal sheet and this resin film-coated metal sheet is embossed. The resultant resin film-coated metal sheet is formed into a can by drawing or by drawing with ironing. The surface roughness is thus enhanced.
Abstract:
Self-metallizing polyimide films are created by doping polyamic acid solutions with metallic ions and solubilizing agents. Upon creating a film, the film is exposed to ultraviolet light for a specific time and then cured. The resulting film has been found to have a metallic surface layer and a metallic subsurface layer (interlayer). The layer separating the metallic layer has a uniform dispersion of small metal particulates within the polymer. The layer below the interlayer has larger metal particulates uniformly distributed within the polymer.
