Zusammenfassung:	PROBLEM TO BE SOLVED: To display far more remarkable easy-to-cut performance compared to a linear low density polyethylene which has been conventionally used as a sealant and at the same time, show the sealing strength and airtightness equal to or higher than those as characteristics of a conventional linear low density polyethylene. SOLUTION: This laminated film with easy-to-cut properties is a laminate consisting of a cyclic olefin resin layer A and at least, each one layer of a linear medium-density polyethylene and/or a linear low-density polyethylene resin layer B, laminated on the surface of the cyclic olefin resin layer A. The thickness of the cyclic olefin resin layer A is preferably equal to 5-30% of the thickness of the entire laminate.
