In the present invention, a compound (A) containing titanium as an essential element and containing a metal element selected from the group consisting of aluminum, zirconium, germanium, tin and silicon is 0.5 to 300 ppm in terms of titanium atoms, and an average particle diameter. It relates to a polyester composition containing 0.001 to 40% by weight of particles having 0.01 to 10 μm, a method for producing the same, and a film made of the polyester composition.n n n Industrial Applicability According to the present invention, problems such as impurity contamination, increase in pressurization and thread breakage can be solved in the production of molded articles such as fibers, films, and combinations which are excellent in molding processability and heat resistance. In addition, the film is suitable for packaging, has excellent taste characteristics and long-term storage properties, and is suitable for molding processing, particularly for laminating molding processing based on paper, nonwoven fabric or metal, and containers. |
