ABSTRACT:
A uniaxially drawn oriented polyolefin film for cable insulation, has a thickness of 80 to 250.mu. and is composed of a crystalline polyolefin having a melt index of 10 or more and 0.5 to 20 phr of unsintered polytetrafluoroethylene, wherein the added unsintered polytetrafluoroethylene is in the form of microfibrous particles uniformly dispersed in the crystalline polyolefin as a matrix so as to be parallel to the orientation axis of the polyolefin; an apparent MI value of the film is 1/4 to 1/10 of the MI value of the crystalline polyolefin used; the tensile Young's modulus of the film in the direction of the orientation axis is 2.times.10.sup.4 kg/cm.sup.2 or more; and the change in the thickness of the film in dodecylbenzene at 100.degree. C. is 10% or less. A method for manufacturing this film is also provided.
