PURPOSE:To prevent occurrence of pinholes by a method in which a polyolefin resin sealant layer of a laminated film having an aluminum foil layer as its intermediate layer is stuck to a polyester resin sealant layer formed on the inside face of a container. CONSTITUTION:A laminated film 200 formed out of an intermediate layer made of an aluminum foil layer 220, the outermost face on one side made of a polyolefine resin sealant layer 210 and the outermost face on the other side made of a polyethylene resin layer 230 is formed on the inside face of a top part 11 and a part to which a plug for an outlet is attached. Such laminated film 200 is applied on the inside face of a container so that the polyolefine resin sealant layer 210 thereof can be stuck to a polyester resin sealant layer 110 of a laminated material 100 on the inside face of the container. Thereby, pinholes hardly occur in packing materials on the closing part on the top part 11 of the container, and the inside face of the container can be fixed firm. |
