Abstract
A hazy polyester film with a thickness in the range from 10 to 100 μm including thermoplastic polyester as the main constituent and barium sulfate with a particle size in the range from 0.1 to 0.5 μm, expressed as d, in an amount in the range from 5 to 25% by weight. The films exhibit a transparency, measured to ASTM-D 1003, of greater than 56% and a haze in the range from 40 to 95%. Owing to their particular optical properties in the form of high transparency with simultaneous scattering action in the form of volume scatter, the film is suitable particularly for use for internal and external window glazing, for interior paneling in bright rooms, for exhibition construction, in vehicles and buildings, in the lighting sector and in shopfitting and shelving.
