摘要： A metalized or ceramic-coated biaxially oriented polyester film is disclosed, with a base layer B which comprises at least 80% by weight of thermoplastic polyester, and with at least one outer layer A. The outer layer A is composed of a copolymer or of a mixture of polymers/copolymers which contains from 90 to 98% by weight of ethylene 2,6-naphthalate units and up to 10% by weight of ethylene terephthalate units, and/or units derived from cycloaliphatic or aromatic diols and/or dicarboxylic acids. The thickness of the outer layer A is more than 0.7 &mgr;m and this makes up less than 25% by weight relative to the entire film. The Tg2 value of the polyester film is above the Tg2 value of the base layer, but below the Tg2 value of the outer layer. The film has low permeability to atmospheric oxygen and exhibits very good adhesion between the individual layers. It is particularly suitable for packaging purposes, specifically for packaging foods or other consumable items.

摘要： 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 SiO2, 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 SiOx, 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.

摘要： Polyester films which comprise, alongside thermoplastic polyester, e.g. polyethylene terephthalate, from 5-45% by weight of poly(m-xyleneadipamide) and optionally from 0.02 to 1% by weight of fillers. The inventive films, which are produced by a sequential stretching process, feature improved mechanical properties, such as a modulus of elasticity greater than 3500 N/mm2 in both orientation directions, high gloss, low haze, and very good barrier properties with respect to oxygen transmission. The inventive films are therefore suitable as packaging material for foods and for other consumable items.
