Definitions

  • Component I of the mixture or blend is a polyethylene terephthalate homopolymer or polyethylene terephthalate copolymer or a mixture of polyethylene terephthalate homo- or copolymers.
  • the object is achieved by a coextruded, amorphous, thermoformable polyester film of the type mentioned at the outset, the distinguishing features of which are that the matt cover layer contains a mixture or a blend of two components I and II.
  • thermoformability means that the films can be thermoformed or thermoformed into commercially available deep-drawing machines without inefficient pre-drying to form complex and large-area shaped bodies.
  • polyesters which are at least 90 mol%, preferably at least 95 mol%, consist of ethylene glycol and terephthalic acid units or of ethylene glycol and naphthalene-2,6-dicarboxylic acid units.
  • the remaining monomer units come from other aliphatic, cycloaliphatic or aromatic diols or dicarboxylic acids, as can also occur in layer A (or layer C).
  • Dicarboxylic acids suitable as component B) of the copolyester are e.g. Malonic, adipic, azelaic, glutaric, sebacic, cork, succinic and brassylic acid as well as mixtures of these acids or their derivatives capable of forming polyesters. Of the acids mentioned, sebacic acid is preferred.
  • M is a monovalent cation of an alkali metal
  • Z is a trivalent aromatic radical
  • component A isophthalic acid
  • component B it applies that any acid with the formula mentioned gives satisfactory results, preference being given to adipic acid, azelaic acid, sebacic acid, malonic acid, succinic acid, glutaric acid and mixtures of these acids.
  • the desired amount within the specified range is preferably 1 to 20 mol%, based on the acid components of mixture II, if component B is contained in the composition.
  • the ratio (weight ratio) of the two components I and II of the cover layer mixture or of the blend can vary within wide limits and depends on the intended use of the multilayer film.
  • the UV stabilizer (s) are preferably contained in the cover layers. If necessary, the core layer can also be equipped with a UV stabilizer.
  • the base layer and the top layer (s) can additionally contain conventional additives, such as stabilizers and antiblocking agents. They are expediently added to the polymer or the polymer mixture before the melting. For example, phosphorus compounds such as phosphoric acid or phosphoric acid esters are used as stabilizers.
  • an intermediate layer between the base layer and the cover layer (s). It can consist of the polymers described for the base layers. In a particularly preferred embodiment, it consists of the polyester used for the base layer. It can also contain the usual additives and the UV stabilizer described.
  • the thickness of the intermediate layer is generally greater than 0.5 ⁇ m and is preferably in the range from 1.0 to 30 ⁇ m, in particular 2.0 to 20 ⁇ m.
  • the present invention also relates to a method for producing this film. It comprises the production of a film from the base and top layer (s) by coextrusion.
  • the polymers for the base layer are expediently fed in via a further extruder. Any foreign bodies or impurities that may be present can be filtered off from the polymer melt before extrusion.
  • the melts are then formed into flat melt films in a multi-layer nozzle and layered on top of one another.
  • the multilayer film is then pulled off and solidified with the aid of a cooling roller and, if appropriate, further rollers.
  • the cooled film is then hemmed and wound up.
  • the substances / compositions mentioned are applied as a dilute solution, emulsion or dispersion, preferably as an aqueous solution, emulsion or dispersion, to one or both film surfaces and the solvent is then volatilized.
  • a temperature treatment is usually sufficient to evaporate the solvent and to dry the coating.
  • the dried coatings then have the desired layer thicknesses mentioned above.

Abstract

La présente invention concerne un feuille polyester amorphe, thermoformable, matte, présentant une couche de base comprenant au moins 80 % en poids (par rapport au poids de la couche de base) d'un polyester thermoplastique et au moins une couche de recouvrement matte. Ladite feuille se caractérise en ce qu'au moins le polyester thermoplastique de la couche de base comprend des éléments monomères qui sont dérivés du diéthylène glycol (DEG) et/ou du polyéthylène glycol (PEG), et en ce que la couche de recouvrement matte comprend un mélange ou une association de deux éléments I et II. L'élément I comprend essentiellement un homopolymère polyéthylène téréphtalate ou un copolymère polyéthylène téréphtalate ou un mélange d'homo- ou copolymères et l'élément II comprend essentiellement un copolymère polyéthylène téréphtalate qui résulte du produit de condensation des monomères suivants ou de leurs dérivés aptes à la formation de polyesters : acide isophtalique, éventuellement un ou plusieurs acides dicarboniques aliphatiques, un sulfomonomère comprenant un groupe métal alcalin-sulfonate dans la partie aromatique d'un acide dicarbonique et la quantité stoechiométrique nécessaire à la formation d'un condensat à 100 % molaires, d'un glycol aliphatique ou cycloaliphatique copolymérisable, l'addition des pourcentages molaires des éléments acide et des éléments glycol donnant un total de 100 % molaires.
