<p>PURPOSE:To obtain laminating material, which develops gas blowing phenomenon, by a structure wherein paper made by mixing polyethylene fibers is provided on the innermost layer side of base material. CONSTITUTION:As base material 1, five-layered paper, for the fifth layer on the innermost layer side of which paper made by mixing polyethylene fibers is employed, is used so as to laminate liquid contacting film 3, which is prepared by laminating aluminum foil, polythylene terephthalate film and polyethylene film to one another in the order named, through melt-extruded polyethylene layer 2 on the fifth layer side of the base material in order to obtain the laminating material concerned. Even when liquid container is produced from said laminating material by applying heating treatments such as flame treatment, top- sealing and the like, no gas blowing phenomenon occurs and consequently development of pin hole and leakage of liquid can be prevented from occurring.</p> |
