PURPOSE:To prevent an insulant from being broken down for allowing a stable production by a method wherein a packaging container is formed of a material which is sealed by high-frequency induction heating, and a coating area of a cover film on which OP varnish (overprint varnish) is applied is located at a position out of contact with an electrode. CONSTITUTION:A main body 1 and a cover film 2 are formed of a material (polyvinyl chloride or polyvinylidene chloride) which is sealed by high-frequency induction heating, and the opening side 1C of the main body 1 is covered with the cover film 2 and adhered together after a content 3 is put in the main body 1. A printing area 4, where characters, etc., are printed by offset or UV offset printing, is provided on the surface of the cover film 2 and coated with OP varnish. The area 5 to be coated with OP varnish is indicated by a dotted line. The outline shows the position of an electrode 8, and the main body 1 and the cover film 2 are bonded together and melt-cut along the outline. |
