PROBLEM TO BE SOLVED: To provide an easily tearable shrink film having excellent properties of cutting in a straight line and does not cause peeling within the layer in a stretched film layer, an easily tearable laminated film using the same, an easily tearable bag, and a process for producing the easily tearable shrink film. SOLUTION: The easily tearable shrink film comprises 60-85 pts.mass nylon 6 (hereinafter referred to as Ny6) and 15-40 pts.mass (the sum of both being 100 pts.mass) m-xylylene adipamide (hereinafter referred to as MXD6) as raw materials, and these raw materials comprise a thermal history product obtained by melt-kneading a virgin raw material composed of 60-85 pts.mass Ny6 and 15-40 pts.mass with Ny6 and MXD6 to render the melting point of MXD6 233-238°C, and the content of this thermal history product is 5-40 mass% on the basis of the entire amount of the raw materials, and the shrinkage of the easily tearable shrink film is 3-20% when the film is maintained in hot water of 95°C for 30 minutes.
