<p><P>PROBLEM TO BE SOLVED: To provide an easily tearable shrink film having excellent straight cutting property and causing no intralayer exfoliation in an oriented film layer, to provide an easily tearable laminated film and an easily tearable bag using the same, and to provide a production method of the easily tearable shrink film. <P>SOLUTION: The easily tearable shrink film comprises 60-85 pts.mass nylon 6 (hereinafter expressed as Ny6) and 15-40 pts.mass methaxylylene adipamide (hereinafter expressed as MXD6) (the sum of both being 100 pts.mass) as raw materials, wherein the raw materials include a virgin material comprising 60-85 pts.mass Ny6 and 15-40 pts.mass MXD6 and a thermal history product provided by melt-kneading the Ny6 and the MXD6 to render the melting point of the MXD6 233-238°C, the content of the thermal history product is 5-40 mass% based on the total raw materials, and the shrinkage of the easily tearable shrink film is 3-20% when the film is held in 95°C hot water for 30 min. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
