POLYESTER FILM CONTAINING GLASS SPHERE AND CALCINED CLAY

Japanese Patent JP3207679

B2

PURPOSE: To obtain a film, e.g. a packaging film, improved in characteristics such as handleability while maintaining acceptable optical clarity and transparency by incorporating therein a combination of glass spheres and calcined clay having specified mean particle sizes.
CONSTITUTION: This film comprises (A) a polyester polymer having incorporated therein (B) a combination of (i) glass spheres present in an amount of 25-350 ppm by weight based on the weight of component A and having a mean particle size of 1-8 μm and (ii) calcined clay present in an amount not exceeding 10,000 ppm based on the weight of component A. It is desirable that the component (ii) has a mean particle size of at most 1 μm and is present in an amount of at most 8,000 ppm based on the weight of component A and that the component (i) has a mean particle size of 2-5.2 μm and is present in an amount of 50-300 ppm based on the weight of component A.
