<p>PURPOSE: Provided are white, biaxially oriented, flame-retardant and UV-resistant polyester film with cycloolefin copolymer, its use and process for its product. The film is suitable for packing foods or other consumable items which are sensitive to light and/or to air, or for use in industry, for an example in the production of hot-stamping foils or as a label film, or for image-recording papers, printed sheets or magnetic recording cards. CONSTITUTION: 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 270deg.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.</p> |
