[0199] Hereinafter, the present invention will be described more specifically using production examples, examples, comparative examples, and test examples. Materials, usage amounts, ratios, operations, and the like shown below can be appropriately changed without departing from the spirit of the present invention. Therefore, the scope of the present invention is not limited to the specific examples shown below. In addition, % described below means mass % unless otherwise indicated.
[0200] [Preparation Example of Resin Composition]
[0201] Thermoplastic resin (propylene homopolymer and high-density polyethylene), metal soap, thermal stabilizer and pore forming nucleating agent (heavy calcium carbonate powder) recorded in Table 1 are in the compounding ratio (unit: Unit: mass %) mixed, melted and kneaded with a twin-screw mixer set at 210°C, then extruded into strands with an extruder set at 230°C, cut with a wire drawing knife after cooling , to obtain, to make particles ...

[0204] [Manufacturing example 1-14 / 16]
[0205] The resin composition for the front surface layer, the resin composition for the core layer, and the resin composition for the back surface layer described in Table 2 were melt-kneaded with three extruders set at 230° C., and supplied to In a feed block type multi-layer die set at 250°C, they were stacked in the die in such a way that the stacking order described in Table 2 was extruded into a sheet, and cooled to 60°C by a cooling device to obtain three layers. Structured non-stretch sheet.
[0206]The obtained unstretched sheet was heated to the temperature in the longitudinal direction described in Table 2 using a heating roll, and stretched in the longitudinal direction (MD direction) at the ratio in the longitudinal direction described in Table 2 by using the difference in peripheral speed of the roller group to obtain a single sheet. Shaft tensile sheet. Next, the obtained uniaxially stretched sheet was cooled to 60° C., ...
manufacture example 15
[0211] On both sides of the obtained resin film of Production Example 3, a polyamine polyamide epichlorohydrin adduct solution (trade name: WS4024, manufactured by Starlight PMC Co., Ltd., solid content concentration 25% by mass) was used in water / 2-propane The solution obtained by diluting the mixture of alcohol = 9 / 1 by 25 times was used as an anchor coating agent, and was applied using an extrusion coater so that the coating amount after drying was 0.02 g / m 2 , dried in an oven at 80° C. to provide an anchor coat layer, and obtain the resin film of Production Example 15. The surface resistivity of the obtained resin film was 10 on both the front and back sides. 14 Ω / □ units.
