Abstract
PURPOSE: To obtain a film which is excellent in transparency and smoothness, by a method wherein a given minute amount of a porous amorphous silica, in which an average particle diameter is of a given value, is blended to a polyester component in which a film haze becomes a given value when molding biaxially-stretched film having a given value of the thickness.
CONSTITUTION: When it is biaxial-stretched into a film having the thickness of 100μ, and when manufacturing a polyester component providing a film whose film haze is below 1%, 1W40ppm of porous amorphous silica, whose average particle diameter is 0.2W2μ, is added to complete a polymerization, and filming takes place by the use of said polyester. The filming method is that, for example, the resin is fused for extrusion in a film state at about 270W295°C, and is then cooled for curing at 50W70°C to form an amorphous sheet. The resultant work is then gradually biaxially-stretched longitudinally and transversely, and is heat-treated at 160W 240°C.
