| titleOfInvention | Method for producing polyolefin microporous film and method for producing laminated porous film |
| abstract | Provided is a method for producing a polyolefin microporous film having a pore structure suitable for a battery separator with high reproducibility and high efficiency without using a special apparatus. A method for producing a polyolefin microporous film comprising the following steps (1) to (3), wherein a raw polyolefin sheet is tenter-stretched. (Step 1) Step of heating the raw material polyolefin sheet (Step 2) Step of performing the first drawing at a predetermined film widening speed while heating the heated raw material polyolefin sheet at a temperature lower than the heating temperature in Step 1. (Step 3) The first drawing while heating the raw material polyolefin sheet subjected to the first drawing at a heating temperature lower than the heating temperature in Step 1 and higher than the heating temperature in Step 2 Step of performing second stretching at a film widening speed smaller than the film widening speed of |
