Abstract
PURPOSE: To improve a high rigidity, an easy tearing property, a transparency and a glossy property and obtain a film more excellent than cellophane by method wherein a Charpy impact strength and an interface average refractive index of a biaxially oriented polypropylene film are limited within a specified range.
CONSTITUTION: A biaxially oriented polypropylene film having 1.510 or more of an interface average refractive index and a Charpy impact strength within a range of 50W130(kg.cm/mm2) is provided. Above-described Charpy impact strength is a reference value for an easy tearing property of the film and if the value is within a range of 50W130kg.cm/mm2, the easy tearing property may be obtained. In order to make the rigid film excellent in a resistance to impact while maintaining the easy tearing property, it is necessary that the interface average refractive index should be 1.510 or more. This is because that, if the interface averge refractive index is less than 1.510, the resistance to impact, Young's modulus and an ultimate strength thereof are made week and the film will lose a high rigidity and a feeling of cellophane.
