<P>PROBLEM TO BE SOLVED: To provide a polyolefin-based resin sheet having excellent heat resistance and dimensional stability by improving the crystallinity of the polyolefin-based resin sheet without carrying out a high-speed and high-pressure rolling elongation. <P>SOLUTION: The method of manufacturing polyolefin-based resin sheet includes: a melting step of melting a polyolefin-based resin to make a molten polyolefin-based resin; a holding step of holding, for a prescribed time, the polyolefin-based resin after melting step, at a temperature above the glass transition temperature (Tg) and below the melting point (Tm); and a pressurizing step of pressuring the polyolefin based resin after the holding step within the temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
