发明名称 POLYPROPYLENE-BASED RESIN SHEET AND POLYPROPYLENE-BASED RESIN VESSEL
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a polypropylene-based resin sheet capable of being thermoformed by prior art into a vessel with a thinned cover and a thinned vessel main body or the like, and capable of giving molded articles such as a vessel manufactured not only transparency but strength such as firmness large enough to endure practical use, and to provide an excellently transparent vessel having strength large enough to endure practical use in spite of its thinness. <P>SOLUTION: The polypropylene-based resin sheet contains as resin components a predetermined amount of a first component composed of one or more polypropylene-based resins each having a MFR value of 1 to 5 g/10 minutes and a predetermined amount of a second component composed of one or more polypropylene-based resins each randomly copolymerized by a metallocene catalyst and having a MFR value smaller than that of the first component. The polypropylene-based resin sheet has a bending modulus of not less than 2,000 MPa in the extrusion direction, a bending modulus of not less than 2,000 MPa in the widthwise direction of the sheet and a haze of not more than 15%. <P>COPYRIGHT: (C)2010,JPO&INPIT</p>
