The invention relates to an opaque, white film with a thickness of from 10 to 500 &#x3bc;m whose principal constituent is a crystallizable thermoplastic. The film comprises at least barium sulfate and at least one optical brightener. The barium sulfate and/or the optical brightener are incorporated directly into the crystallizable thermoplastic or are fed as a masterbatch during film production. At least one surface of the film bears a functional coating with a thickness of from 5 to 100 nm, in order to confer on the film surface an additional function such as sealability, printability, metallizability, sterilizability, antistatic properties, aroma barrier properties or improved adhesion to materials which would not adhere to the film surface without the coating, for example photographic emulsions.

Opaque, white film with low transparency made from a crystallizable thermoplastic and having additional functionality

The present invention relates to an opaque, white UV-stabilized low-flammability film with a thickness of from 10 to 500 &#x3bc;m whose principal constituent is a crystallizable thermoplastic. It also comprises at least barium sulfate as pigment, at least one flame retardant, at least one UV stabilizer as light stabilizer and at least one optical brightener. The barium sulfate and/or the optical brightener and/or the flame retardant and/or the UV stabilizer here is either incorporated directly into the thermoplastic when the polymer is prepared or fed to the thermoplastic 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, and also for outdoor applications, such as roofing systems, external cladding, protective coverings, applications in the construction sector, or illuminated advertising profiles, or in the transport sector, or else for electrical applications.

Opaque, white UV-stabilized low-flammability film with low transparency made from a crystallizable thermoplastic

A white film whose thickness is in the range from 1 to 500 &#x3bc;m and which comprises, as principal constituent, a crystallizable thermoplastic, wherein the film comprises at least one UV stabilizer as light stabilizer and at least one white pigment, the use of the film, and also a process for its production.

Opaque, white film with low transparency made from a crystallizable thermoplastic

The invention relates to a white, biaxially oriented film made from a crystallizable thermoplastic with high whiteness, the thickness of the film being in the range from 10 to 500 &#x3bc;m. The film comprises at least one rutile-type titanium dioxide as pigment and an optical brightener, with or without other additives, and has at least one additional functionality. The expression 'additional functionality' includes UV resistance, yellowing resistance, photooxidative stability, flame retardancy, and sealability. This film may have one or more of the functional properties. All of these films are capable of cost-effective thermoforming, have good orientability, and have very good optical and mechanical properties. The invention further relates to a process for its production.

White, biaxially oriented film made from a crystallizable thermoplastic with high whiteness and with additional functionality

The invention relates to a white film with a thickness in the range of 1 to 500 &#x3bc;m that contains a crystallizable thermoplast as the main component. The inventive film is further characterized in that it contains at least one UV stabilizer as the light stabilizer and at least one white pigment. The invention further relates to a method for producing said film and the use thereof.

White UV-stabilized thermoformable film made from a crystallizable thermoplast, method for producing the same and its use

A transparent film whose thickness is in the range from 1 to 500 &#x3bc;m and which comprises, as principal constituent, a crystallizable thermoplastic, wherein the film comprises at least one UV stabilizer as light stabilizer and at least one optical brightener, and to the use of the film, and also to a process for its production.

Transparent, UV-stabilized film made from a crystallizable thermoplastic

The invention relates to a white film with a thickness of from 10 to 500 &#x3bc;m whose principal constituent is a crystallizable thermoplastic. It also has to comprise at least one titanium dioxide of the rutile type as white pigment and at least one optical brightener. The optical brightener and/or the titanium dioxide are fed as a masterbatch during film production. A white film of this type is particularly suitable for interior decoration, for constructing exhibition stands, for exhibition requisites, for displays, for placards, for labels, in the fitting out of shops or of stores, as a promotional requisite or as a laminating material or for applications associated with food or drink.

White biaxially oriented film made from a crystallizable thermoplastic and having a high level of whiteness

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

White, sealable, flame-retardant, biaxially oriented polyester film, its use and process for its production

The invention relates to a white, flame-resistant, UV-stable, thermoformable, oriented film made from a crystallizable thermoplastic, the thickness of which lies in the range of from 10 &mgr;m to 350 &mgr;m. Said film comprises at least one white pigment, a flame-proofing agent and a UV absorber and is characterized by good stretchability and thermoformability, by good optical and mechanical properties and an economical production.
