PROBLEM TO BE SOLVED: To provide an easy-tearing film having excellent tearability and linear cutting property, and sufficient impact strength, and also provide its manufacturing method. SOLUTION: A raw material containing 40-85 pts.wt. nylon 6 (Ny 6) and 15-60 pts.wt. methaxylylene adipamido (MXD 6), where My 6 + MXD 6 = 100 pts.wt., is mixed, and the mixture is melt-extruded. Next, a cooled original film 11 is biaxially oriented in MD direction (the film moving direction) and TD direction (the film width direction) by a draw ratio of at least 2.8, for obtaining an easy-tearing film 18. |
