ABSTRACT:
The present invention relates to an opaque, white film with a thickness of from 10 to 500 μm whose principal constituent is a crystallizable thermoplastic. It also comprises at least barium sulfate and at least one optical brightener. The barium sulfate and/or the optical brightener here is either incorporated directly into the thermoplastic during preparation of the polymer or fed as a masterbatch during film production. The novel film is particularly suitable for interior decoration, for constructing exhibition stands, for exhibition requisites, for displays, for placards, for labels, for protective glazing of machines or of vehicles, in the lighting sector, in the fitting out of shops or of stores, as a promotional requisite or a laminating material, or in applications associated with food or drink.
