摘要

[Topic] the stretching seat and the thermal compact which include the propylene resin composition, and the said resin composition for the stretching seat which possesses rigidity, heatproof rigidity, transparency, uniform stretching characteristic, and the thermal compactibility which are superior are offered. As for the propylene resin composition for stretching seat of this invention, the high fusion point propylene resin where the fusion point which was measured with DSC is 156 - the 170 (A') 10 - 90 weight %, at least low the fusion point propylene resin above the kind where the fusion point which was measured with DSC is 70 - the 155 (the A'') 10 - 90 weight % (however, as for total of the A'to A '' 100 weight %) with including, it becomes, description below [it features that important matter of 1] - [4] is satisfied. [1] melt flow rate (the 230 , the 2.16kg load) is 0.5 - 10.0g/10min. [2] the fusion point which was measured with DSC is 150 - the 170 . [3] the propylene resin composition for stretching seat (A) in, olefin comonomer content is 1 - 11mol%. [4] the structure nuclear component is included.
