Peelable polyester film having improved oxygen barrier, process for its production and its use

This invention relates to a coextruded, transparent, biaxially oriented polyester film comprising a base layer (B) and a heatsealable top layer (A) which is peelable from at least the APET side of an APET/CPET tray, the heatsealable and peelable top layer (A) consisting of The invention further relates to a process for producing the film and to its use.

Coextruded, hot-sealable and peelable polyester film having high peeling resistance, process for its production and its use

This invention relates to a coextruded, transparent, biaxially oriented polyester film comprising a base layer (B) and a heatsealable top layer (A) which is peelable from at least APET, the heatsealable and peelable top layer (A) consisting of

Three-layer, highly oriented polyester films having an A-B-C layer construction, preferably made of polyethylene terephthalate, which, in addition to a base layer B, have a smooth surface layer A which contains no external particles and a rough surface layer C which contains external particles such as antiblocking agents or pigments, preferably SiO, in defined amounts and particle sizes, feature in particular good producibility and processibility, high gloss of the film surface A and low opacity. The very smooth surface A is suitable in particular for coating with materials, for example SiO, by means of plasma polymerization of hexamethyldisiloxane by the CVD or PECVD method, which provides the film with a high oxygen barrier and is suitable in particular as packaging for light- and air-sensitive foods or other consumable items.

The invention relates to a white, biaxially-oriented and coextruded polyester film which is matt on at least one side with at least one base layer B, which contains a cycloolefin copolymer (COC) in amounts of 4 to 60 wt. %, based on the weight of the base layer, in addition to polyester starting material. The glass transition temperature Tof the COC lies in the range from 70 to 270&#xb0; C. Said film has at least one matt outer layer (A), made from polyester and is particularly suitable for use in fast running machines such as winding, metallising, printing or laminating machines.

White, biaxially-oriented polyester film with cycloolefin copolymer (COC), which is matt on at least one side, method for production and use thereof

The present invention relates to a high-whiteness, biaxially oriented polyester film with at least a base layer made from polyester. The base layer of the polyester film of the invention also comprises from 2 to 60% by weight of a cycloolefin copolymer (COC), from 0.1 to 25% by weight of a white pigment, and, if desired, from 0 to 5% by weight of an optical brightener, based on the weight of the base layer. The glass transition temperature of the COC here is to be within the range from 70 to 270&#xb0; C. The film is particularly suitable for packing foods or other consumable items which are sensitive to light and/or to air, or for use in industry, e.g. for producing hot-stamping foils or as a label film, or for image-recording papers, printed sheets, or magnetic recording cards, or for processing on high-speed machinery for winding, metallizing, printing or laminating.

High-whiteness, biaxially oriented polyester film, its use and process for its production

The invention relates to a transparent, biaxially oriented polyester film with a base layer B which is composed of at least 80% by weight of a thermoplastic polyester, and with at least one outer layer A. Another polymeric layer made from a copolymer crosslinked using an acrylic and/or methacrylic compound, has been applied to that side of the film opposite to the outer layer A. The film has low oxygen transmission and exhibits very good adhesion between the respective layers. The coated film moveover has low coefficient of friction, excellent windability, and excellent antistatic performance. It is particularly suitable for packaging purposes, specifically for packaging foodstuffs or other consumable items. The invention further relates to a process for the production of the film.
