Propylene polymer composition, unstretched film, and laminate

The technical problem to be solved by the present invention is to provide a propylene polymer composition capable of forming an unstretched film having superior rigidity than conventional unstretched films. [Solution] This propylene polymer composition is characterized by containing a specific propylene polymer (A) and a propylene polymer (B) having a melting point of 120-170 DEG C and an intrinsic viscosity [eta] of more than 1.5 dl/g and 5.0 dl/g or less as measured in a tetralin solvent at 135 DEG C, the content of the propylene-based polymer (A) is 2-30 parts by mass and the content of the propylene-based polymer (B) is 70-98 parts by mass per 100 parts by mass of the total of the propylene-based polymer (A) and the propylene-based polymer (B). 本发明所要解决的技术问题在于，提供一种能够形成刚性比现有的无拉伸膜优异的无拉伸膜的丙烯系聚合物组合物。本发明的解决方法在于，该丙烯系聚合物组合物的特征在于：含有特定的丙烯系聚合物(A)和熔点为120～170℃、并且以135℃、在四氢化萘溶剂中测得的特性粘度[η]超过1.5dl/g且为5.0dl/g以下的丙烯系聚合物(B)，相对于上述丙烯系聚合物(A)和上述丙烯系聚合物(B)的合计100质量份，上述丙烯系聚合物(A)的含量为2～30质量份，上述丙烯系聚合物(B)的含量为70～98质量份。
