PROBLEM TO BE SOLVED: To provide a package filling method, a packaging paper container and a laminated packaging paper for a paper container for a fluid food which is heat-resistant, transports the packaging material at a high speed at the process atmosphere temperature of several dozen degrees C or more, molds the material nicely, easily and speedily with no generation of a defect on a packaging material laminated body, and has a superior low temperature sealing characteristic with no barrier defect and sealing defect. SOLUTION: This container is made of a laminated packaging material for a paper container including the outermost thermoplastic material layer, a paper base material layer the an innermost thermoplastic material layer and in which a content is filled and sealed. At least the innermost thermoplastic material layer of the laminated layers is a laminated layer formed by extrusion laminating a linear low density polyethylene and a high density polyethylene in narrow molecular weight distribution.
