ABSTRACT:
Disclosed is a sealant film having at least two layers including a base layer (X) and a sealant layer (Y) as essential constituents, the 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), the sealant layer (Y) comprising a polyolefin resin composition (BB), wherein the polyolefin resin (A) is an ethylene polymer (A1) and/or a propylene polymer (A2). Since the sealant film has an excellent balance between heat-sealing properties and easy peel properties, it does not suffer angel hair (nappy phenomenon) even at a lower sealing strength and has good appearance after peeling. The film can be favorably used for forming a food packaging container.
