<p>PROBLEM TO BE SOLVED: To employ an inorganic compound evaporation thin film having a thermoplastic resin film as a support film for aluminum foil, and thus render an anti-impact property superior during falling by the use of a polyethylene resin layer manufactured through the use of a metallocene catalyst to at least the outermost layer of the resin layer of a laminate material. SOLUTION: A paper container laminate material 10 is a film manufactured by making the polyethyleneterephthalate surface of a polyethyleneterephthalate film 15 given a silicon dioxide evaporation film 14 adhere to a polyethylene film 16. Particularly, a polyethylene resin layer 11 manufactured by the use of a metallocene catalyst is formed on the surface of a cardboard 12 through an extrusion lamination method, after that, by the rear surface of the cardboard 12 and the surface of the silicon dioxide evaporation thin film 14 of the adhered film, sandwich lamination is conducted for molten polyethylene 13. With this laminated material 10, a liquid paper container is formed, and a part of trunk joint parts is subjected to a skive-hemming process to manufacture a paper container.</p> |
