[PROBLEMS] To provide a polyethylene resin laminate film, more specifically a polyethylene resin film having a good balance of heat-sealing property and stiffness of the film, having less fish-eyes, having little fisheyes and also having less unevenness in thickness. [MEANS FOR SOLVING PROBLEMS] A polyethylene resin laminate film having at least a laminate layer (A) and a seal layer (B), the laminate layer (A) comprising at least two polyethylene resins each having a density of 900 to 970 kg/m^3 and a molecular weight distribution (Mw/Mn) of 2. 0 to 3.5, the densities of the at least two polyethylene resins being different from each other, the average density of the laminate layer being 920 to 945 kg/m^3, the seal layer (B) comprising a polyethylene resin having a density of 900 to 930 kg/m^3, and the average density of the laminate layer (A) being larger than that of the seal layer (B). ® KIPO & WIPO 2008
