Abstract: Disclosed is a sealant film has at least two layers including a base layer (X) and a sealant layer (Y) as essential constituents, said base layer (X) comprising a resin composition (AA) which comprises 50 to 98% by weight of a polyolefin resin (A) and 2 to 50% by weight of a tackifier (B), said sealant layer (Y) comprising a polyolefin resin composition (BB), wherein the polyolefin resin (A) is an ethylene polymer (A1) having a melt flow rate (MFR, ASTM D 1238, 190 DEG C, load of 2.16 kg) of 0.1 to 50 g/10 min and a density (ASTM D 1505) of 0.850 to 0.960 g/cm and/or a propylene polymer (A2) having a melt flow rate (MFR, ASTM D 1238, 230 DEG C, load of 2.16 kg) of 1 to 100 g/10 min, and the tackifier (B) has a glass transition temperature of 20 to 140 DEG C and a number-average molecular weight of 1200 or less. Since the sealant film has an excellent balance between heat-sealing properties and easy peel properties, does not suffer angel hair (nappy phenomenon) even when it has lower sealing strength and has good appearance after peeling, the film can be favorably used for forming a food packaging container.
