The present invention relates to a transparent, peelable polyester film incorporating at least one biaxially oriented polyester film (=base layer (B)) and at least one peelable covering layer (A) coated offline thereon, in which the covering layer (A) is at least 85 wt. % made up of a polyester of aromatic and aliphatic dicarboxylic acids and aliphatic diols, and the arithmetic mean value of the absolute ordinate values Sof the covering layer (A) is less than 300 nm and the reduced peak height Sof the covering layer (A) is less than 700 nm. The invention further relates to a production process for this peelable film and use thereof as sealing film for APET and/or RPET meal trays.

Biaxially oriented, heat-sealable and peelable polyester film, process for production thereof and use thereof

A transparent peelable polyester film is provided having a base layer (B) with first and second surfaces. A layer (C) is applied on the base layer (B). A heat-sealable layer (A), peelable to APET AND RPET, is applied on the opposing surface of the base layer (B). The heat-sealable and peelable outer layer (A) is formed from

Peelable polyester film, use thereof and process for production thereof

The invention relates to transparent packaging for vacuum forming, inter alia, formed from a biaxially oriented, thermoformable polyester film as lower film (A) and a biaxially oriented polyester film as upper film (B) that is both heat-sealable and peelable (at least when the material is hot) in relation to the lower film (A). The present invention further relates to the use of such packaging to produce sealed, thermoformed packs, and to the processes for their respective production.

Pack made of polyester with a thermoformable lower film and a sealable and peelable upper film, use thereof, and process for its production

The present invention relates to a transparent, biaxially oriented, thermoformable polyester film including at least 85% by weight of a copolyester whose dicarboxylic acid components derive to an extent of 85 to 94 mol % from terephthalic acid-based units and to an extent of 6 to 15 mol % from isophthalic acid-based units. The inventive films exhibit a surface elasticity modulus in the range from 4500 to 6400 N/mm; a sum total of the strengths (&#x3c3;) in longitudinal direction and in transverse direction in the range from 170 to 220 MPa; a density of less than 1390 kg/m; a haze of less than 2.0%; a clarity of at least 85%; a gloss of at least 120 and a thickness in the range from 50 to 300 &#x3bc;m. The invention further relates to processes for producing such films, and to the use thereof.

Transparent, thermoformable, biaxially oriented polyester film, process for production thereof and use thereof

A transparent, peelable polyester film is provided with clarity greater than 80% including a biaxially oriented polyester film as base layer (B) and an offline coated heat-sealable outer layer (A) that is peelable relative to ready-meal APET or RPET trays. The heat-sealable and peelable outer layer (A) includes from 85 to 99 wt % polyester and from 1 to 15 wt % other substances, the polyester including of from 25 to 95 mol % of units derived from at least one aromatic dicarboxylic acid and from 5 to 75 mol % of units derived from at least one aliphatic dicarboxylic acid. The polyester incorporates at least 10 mol % of units derived from diols having more than 2 carbon atoms. The mass of the dry outer layer (A) is from 1 to 5 g/m. Production processes for the foregoing film, and use thereof as scalable film for ready-meal trays is also provided.

Heat-sealable and peelable polyester film, use thereof and process for production thereof

The present invention relates to a transparent packaging for vacuum forming including a specific biaxially oriented thermoformable polyester foil as lower foil (A) and a specific biaxially oriented polyester foil as upper foil (B) that can be heat-sealed to the lower foil (A), and to a process for the production of such packing, and also use thereof.

Thermoformable transparent packing made of polyester with a lower foil and an upper foil, process for production thereof and use thereof

The invention relates to a sealable, biaxially oriented polyester film comprising a base layer B, a sealable cover layer A, and a non-sealable cover layer C. The invention further relates to a method for producing the film and to the use thereof.

Sealable biaxially oriented polyester film

The invention relates to a multilayer, white, biaxially oriented polyester film, which has a base layer B and at least one outer layer (A), where

Multilayer, white polyester film

The invention relates to a biaxially oriented polyester film, preferably PET film, which has a hydrophilic coating on at least one surface. The coating composition used to form the hydrophilic coating includes water, a sulfopolyester, a surfactant, and optionally an adhesion-promoting polymer. The inventive films have a hydrophilic surface which inhibit condensation of water droplets on the films.

Polyester film with hydrophilic coating

The invention relates to a biaxially oriented polyester film having a base layer (B) which comprises at least 80% by weight of a polyester comprised of from 55 to 90 mol % of units deriving from at least two aromatic dicarboxylic acids and of from 5 to 45 mol % of units deriving from at least one aliphatic dicarboxylic acid, where the total of the dicarboxylic-acid-derived molar percentages is 100. The film features ultimate tensile strength of &#x2266;100 N/mmand modulus of elasticity of &#x2266;3000 N/mm.

Polyester film with low mechanical strength

This invention relates to 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 The invention further relates to a process for producing the film and to its use.

Coextruded, hot-sealable and peelable polyester film, process for its production and its use

Coextruded, biaxially oriented polyester films which have a base layer (B) and have a heatsealable outer layer (A) that can be peeled from APET/CPET and from CPET, where the outer layer (A) includes

Adhesion-promoted , heatsealable and peelable polyester film, process for its production and its use

The invention relates to an aqueous coating composition which comprises a mixture of polyvinylpyrrolidone, a surfactant and optionally an adhesion-promoting polymer. This mixture is suitable for inline coating of biaxially oriented polyester films. The thus obtained films feature a characteristic hydrophilic surface which prevents the fogging of the films with water droplets.
