A hazy polyester film with a thickness in the range from 10 to 100 &#x3bc;m including thermoplastic polyester as the main constituent and barium sulfate with a particle size in the range from 0.1 to 0.5 &#x3bc;m, 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.

Hazy polyester film with improved technology

The present application relates to a white, biaxially oriented, flame-retardant, UV-resistant polyester film with at least one base layer which comprises, based on the weight of the base layer, from 2 to 60% by weight of a cycloolefin copolymer (COC), where the glass transition temperature of the COC is within the range from 70 to 270&#xb0; C. The film also comprises from 0.01 to 5.0% by weight of a UV stabilizer as light stabilizer and also comprises from 0.5 to 30% by weight of flame retardant, based in each case on the weight of the layer comprising the UV stabilizer and/or comprising the flame retardant. The film of the invention is suitable for packing foods or other consumable items which are sensitive to light and/or to air, or for use in industry, e.g. in the production of hot-stamping foils or as a label film, or for image-recording papers, printed sheets or magnetic recording cards.

White, biaxially oriented, flame-retardant and UV-resistant polyester film with cycloolefin copolymer, its use and process for its production

The invention concerns a unilaterally mat, sealable, UV-stabilized and flame-resistant, sealable, co-extruded, biaxially oriented polyester film comprising at least one base layer (B) and a sealable top coating (A) applied to both sides of said base layer, in addition to a mat covering (C). The film also contains at least one UV stabilizer as a light stabilizer. The invention further concerns a method for the production of said film and the use thereof.

Unilaterally mat, sealable, UV-stabilized, flame resistant, co-extruded, biaxially oriented polyester film, method for the production and the use thereof

The invention relates to a sealable, UV-resistant and flame-retardant, coextruded, biaxially oriented polyester film with one matt side and composed of at least one base layer B and of, applied to the two sides of this base layer, a sealable outer layer A and matt outer layer C. The film also comprises at least one light stabilizer which is a UV stabilizer, and comprises a flame retardant. The invention also includes the use of the film and a process for its production.

The invention relates to a sealable, flame-retardant, coextruded, biaxially oriented polyester film with one matt side, and composed of at least one base layer B and of, applied to the two sides of this base layer, a sealable outer layer A and a matt outer layer C. The film also comprises at least one flame retardant. The invention further relates to the use of the film and to a process for its production.

Sealable, flame-resistant, co-extruded, biaxially oriented foil that is mat on one side and a method for producing and using same

The invention relates to a biaxially oriented polyester film having at least two layers and which, together with good processing performance, after it has been metalized or has been coated with oxidic materials, is a very good gas or oxygen barrier, and which has been built up from at least one base layer and at least one outer layer applied to this base layer, where the film has a planar orientation &Dgr;p of greater than
