Biaxially oriented mono- or multilayered polyester film containing at least one UV stabilizer according to formula (I): wherein and

Mono- or multilayer stabilized polyester film

A process is described for production of a biaxially oriented film which comprises at one crystallizable thermoplastic as main constituent and comprises at least 500 ppm, based on the weight of thermoplastic, of a pigment. The production process uses at least 20% by weight, based on the weight of the film, of recycled material of the same type whose molecular weight has been increased by condensation processes.

Process for production of biaxially oriented films based on crystallizable thermoplastics, using recycled material whose molecular weight has been increased by condensation processes

The invention relates to a polyester film with a thickness of from about 4 to about 23 &#x3bc;m, which comprises, alongside polyethylene terephthalate as main constituent, from about 2 to about 20% by weight of polyethylene naphthalate (based on the weight of the film), and has fewer than 30 pinholes per 100 m. The invention further relates to a process for producing these films, and to the use of the films in packaging composites.

Transparent film made from PET and PEN with UV protection, process for producing the film, and use of the film in packaging with extended shelf life

The invention relates to a white opaque film formed from a crystallizable thermoplastic, preferably thermo-plastic polyester in the form of polyethylene terephthalate, barium sulfate and titanium dioxide as pigments, at least one optical brightener, and optionally at least one dye soluble in the thermoplastic. The film optionally includes, an additional functionality, e.g. in the form of an adhesive coating, of a coating with aminosilane or silicone, of UV resistance, of hydrolysis resistance, of flame retardancy, or of a sealable outer layer.

White opaque film having low transparency and improved dielectric strength

The invention relates to an at least two-layer polyester film with a total thickness of from about 5 to about 200 &#x3bc;m which comprises polyethylene terephthalate and from about 2 to about 20% by weight&#x2014;based on the weight of the entire film&#x2014;of polyethylene naphthalate, and also at least one functional outer layer.

Multilayer, transparent film made from PET and PEN with at least one functional outer layer for producing composite packaging with UV resistance

Invention relates to a process for producing a single-layer or multilayer film by extrusion or coextrusion, biaxial orientation, and heat setting based on crystallizable thermoplastics whose principal constituent is a crystallizable thermoplastic having a standard viscosity SV (DCA) of from 600 to 1000. The thermoplastic is mixed prior to extrusion or coextrusion with 50% by weight (based on the total weight of all thermoplastics) of a secondary thermoplastic having a standard viscosity SV (DCA) of more than 900 to 1500, the standard viscosity SV (DCA) of the two thermoplastics differing by at least 100 units. The secondary thermoplastic is a byproduct or waste product from the production of PET plastic bottles or originates from recycled PET bottles.

Process for producing a thermoplastic film using plastic bottle recyclate

Biaxially oriented polyester films formed from a crystallizable polyester having increased diethylene glycol content and/or increased polyethylene glycol content, and/or increased isophthalic acid content, preferably polyethylene terephthalate. The films of the invention further include at least one IR-reflective pigment and one UV stabilizer. The inventive films feature adjustable mattness, diffuse scattering power for visible light, high light transmittance and IR reflectance and good thermoformability, and are suitable for thermally protective coatings or thermally protective packaging.

Matt, thermoformable, IR-reflective polyester film

Multilayer, biaxially oriented polyester films which include as a constituent of the base layer B, a crystallizable polyester with increased diethylehe glycol content and/or increased polyethylene glycol content, and/or increased isophthalic acid content, preferably polyethylene terephthalate. The outer layers of the inventive films advantageously include at least one IR-reflective pigment and one UV stabilizer. The inventive films advantageously feature adjustable mattness, diffuse scattering power for visible light, high light transmittance, IR reflectance, and good thermoformability, and are suitable for thermally protective coatings or thermally protective packaging.

Multilayer, matt, thermoformable, IR-reflective polyester film

The invention relates to a white, biaxially oriented film which comprises a crystallizable thermoplastic as main componet and is characterized by further comprising at least one UV-stabilizer, at least one white pigment and at least one flame-proofing agent, which is soluble in the thermoplastic and introduced directly, during the film production, by masterbatch technology, whereby the masterbatch is pre-conditioned by gradual heating under reduced pressure and with stirring.

White flame-resistant uv-stable film made from a crystallizable thermoplastic, a method for production and the use thereof

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

Biaxially oriented, co-extruded polyester films comprising a base layer consisting of at least 90 wt. % thermoplastic polyester, preferably polyethylene terephthalate (PET), at least one sealable outer layer and a second non-sealable outer layer and, optionally, other intermediate layers, in addition to at least one flame-retardant agent, preferably organic phosphorous compounds. The inventive films are characterized by low inflammability, high UV stability, no embrittlement when subjected to thermal stress and a surface which is devoid of troublesome opacity. They are suitable for a multiplicity of uses both indoors and outside. The outer layers contain anti-blocking agents such as silicic acid having an average particle diameter of preferably less than 50 nm and/or 2 &#x3bc;m. Preferably, the sealable outer layer consists of a copolyester which is made of ethylene terephthalate and ethylene isophthalate units.

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.
