PROBLEM TO BE SOLVED: To obtain a polyolefin laminated film which is good at surface printability and the melt-cut seal strength of a gusset part and free from the coloring of the end face of a film-wound product, the deterioration of transparency after the passage of time, and offensive odors. SOLUTION: A polyolefin laminated film is the laminate of a resin composition layer A consisting of 50-99 wt.% of a crystalline propylene polymer in which a molecular weight distribution (Mw/Mn) expressed by the ratio of weight average molecular weight(Mw) to number average molecular weight(Mn) is 1.8-4.0, a temperature increase elution fraction elution curve with a measurement starting temperature made 10 deg.C exhibits one eluted component peak at 30 deg.C or above, a peak temperature is 70-120 deg.C or below, and an elution temperature width of a half peak height is 2.5-6 deg.C and 50-1 wt.% of a low crystalline or noncrystalline olefin polymer whose crystallinity measured by X-ray diffraction is 0-30% and a polyolefin layer B, and the layer A is a surface layer. |
