Abstract

[PROBLEMS] To provide a film roll which is satisfactory in blocking resistance and slip properties, is free from rumples, and has satisfactory processability. [MEANS FOR SOLVING PROBLEMS] The film roll has a haze regulated to a value within a given range, and the film comprises a base layer and a sealing layer which are constituted of a polypropylene resin formed by the vapor deposition method. When samples are taken out respectively from ten sampling parts disposed at equal intervals throughout the film from the winding initiation point to the winding termination point and are examined for coefficient of dynamic friction at 40°C, amount of an anti-fogging agent present on the film surface, and air escape index, then the values of the following properties are within respective ranges: the average coefficient of dynamic friction, coefficient of fluctuation in coefficient of dynamic friction, average surface anti-fogging agent amount, coefficient of fluctuation in surface anti-fogging agent amount, average air escape index, and coefficient of fluctuation in air escape index. Furthermore, the coefficient of thickness fluctuation for the whole machine-direction length has been regulated to a value within a given range.
