PURPOSE:To constitute the titled film so that excellent blocking resistance is displayed through loading of a small quantity of spherical particulates and that transparency and strength do not substantially deteriorate, by combining use of the specific spherical particulates to polyolefin with specific orientation treatment to the same. CONSTITUTION:The titled film contains condensation type resin (hereinafter referred to as spherical particulates) having a spherical triazine ring, whose mean particle diameter is 0.5-10mu, to polyolefin at the rate of 0.01-0.1wt%, desirably 0.05wt%, and is oriented unidirectionally at least more than four times. The spherical particulates used herein indispensably have the triazine ring; when an existence ratio decreases, an effect decreases. Then it is necessary that an existence quantity of a triazine series monomer occupying within the spherical particulates is more than 50wt%. With this construction, this film is capable of giving excellent blocking resistance by loading a small quantity of the spherical particulates without making transparency deteriorate. |
