Matte, coextruded polyester film, its use and process for its production |
摘要 |
The invention relates to a biaxially oriented polyester film with a base layer at least 80% by weight of which is composed of a thermoplastic polyester, and with at least one matte outer layer which comprises a mixture or a blend of two components I and II wherein components I and II render the at least one outer layer matte. The invention further relates to the methods for use of the film and to a process for its production. Component I of the mixture or of the blend is a polyethylene terephthalate homopolymer or polyethylene terephthalate copolymer or a mixture of homo- or copolymers. Component II of the mixture or of the blend is a polyethylene terephthalate copolymer which is composed of the condensation product of the following monomers and/or of their derivatives capable of forming polyesters: isophthalic acid, aliphatic dicarboxylic acid, sulfomonomers and aliphatic or cycloaliphatic glycols. The outer layer according to the invention has a characteristic matte surface and/or appearance and is highly suitable for use as a packaging film, specifically for packaging foods and other consumable items, and for laminating, metallizing and printing, or for applications in the industrial sector.
