  • Publication number: 20030004237
    Abstract: The invention concerns transparent, flame retardant, thermoformable, UV-stabilized, single layered or multilayered films, containing a cristallizable thermoplastic material, preferably polyethyleneterephthalate, at least one flame retarding agent and a UV stabilizer as main components. Said films are characterized by good stretchability, thermoformability and good optical and mechanical properties, which makes them and the shaped bodies made from said films suitable for both inner and outer applications.

  • Publication number: 20020187328
    Abstract: 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 &mgr;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.

  • Publication number: 20020150751
    Abstract: Biaxially oriented, coextruded polyester films with a base layer at least 90% by weight of which is composed of a thermoplastic polyester, preferably polyethylene terephthalate (PET), and with at least one sealable outer layer and a second nonsealable outer layer and, if desired, with other intermediate layers, and comprising at least one UV absorber, preferably hydroxybenzotriazoles and triazines, have high UV resistance, do not embrittle when exposed to high temperatures, have a surface without undesirable haze and are suitable for numerous indoor and outdoor applications. The outer layers comprise antiblocking agents, such as silica with an average particle diameter preferably below 50 nm and/or above 2 &mgr;m, and the sealable outer layer is preferably composed of a copolyester which has been built up from ethylene terephthalate units and ethylene isophthalate units.

  • Publication number: 20020136875
    Abstract: The invention relates to a white film with a thickness of from 10 to 500 &mgr;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.

  • Publication number: 20020136880
    Abstract: The invention relates to an opaque, white film with a thickness of from 10 to 500 &mgr;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.

  • Publication number: 20020136879
    Abstract: The present invention relates to an opaque, white film with a thickness of from 10 to 500 &mgr;m 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.

  • Publication number: 20020115757
    Abstract: The present invention relates to an opaque, white UV-resistant low-flammability film with a thickness of from 10 to 500 &mgr;m whose principal constituent is a crystallizable thermoplastic. It also comprises at least barium sulfate, at least one UV stabilizer and at least one optical brightener. The barium sulfate and/or the optical brightener and/or the UV stabilizer here is either incorporated directly into the thermoplastic when the polymer is prepared or fed as a masterbatch during film production.

  • Publication number: 20020065346
    Abstract: The invention relates to transparent, biaxially oriented and heat-set films having one or more layers and compris, as main constituent, at least one crystallizable thermoplastic, in particular a polyester, and also comprise at least one hydrolysis stabilizer. The hydrolysis stabilizer is preferably a phenolic compound, an oxazoline, and/or a monomeric or polymeric carbodiimide, where appropriate combined with an organic phosphite. It is preferably added in the form of a masterbatch. The film exhibits low longitudinal and transverse shrinkage. On exposure to moisture and heat it shows practically no embrittlement and retains its ultimate tensile strength. The additional functionality is preferably that the film has been made UV-resistant, or flame-retardant, or on one side or on both sides has been coated, or is sealable, and/or has been corona- or flame-treated.

  • Publication number: 20010018476
    Abstract: The present invention relates to a transparent, low-flammability, UV-resistant, oriented film made from a crystallizable thermoplastic and having a thickness of from 5 to 300 &mgr;m. The film comprises at least one UV stabilizer and at least one flame retardant, and at least the flame retardant, and preferably also the UV stabilizer, is fed directly as a masterbatch to the crystallizable thermoplastic during production of the film. The film may have one or more layers, and the UV stabilizer may have been selected from the group consisting of the 2-hydroxybenzophenones, the 2-hydroxybenzotriazoles, the organonickel compounds, the salicylic esters, the cinnamic ester derivatives, the resorcinol monobenzoates, the oxanilides, the hydroxybenzoic esters, the sterically hindered amines and triazines, and the flame retardant may be an organic phosphorus compound, in particular an organic phosphorus compound soluble in polyethylene terephthalate.
