PROBLEM TO BE SOLVED: To provide a propylene laminated film having excellent low-temperature heat seal characteristics of the film, which does not cause any defective appearance such as sharkskin or scaly patterns even if the propylene laminated film is manufactured, and the heat sealable package film using the same. SOLUTION: The propylene laminated film includes a sealant layer made of a propylene resin composition having an MFR measured at 230°C and 2.16 Kg load of 2.0-20 g/10 min and including: 50-99 wt.% of a high molecular weight ethylene-propylene random copolymer (A) polymerized using a metallocene catalyst having an ethylene content of 1.0-6.0 wt.% and an Mw of 270,000-460,000; and 1-50 wt.% of an extra-low molecular weight ethylene-propylene random copolymer (B) polymerized using a metallocene catalyst having an ethylene content of 1.0-6.0 wt.% and an Mw of 29,000-130,000.
