MATTE MULTILAYER POLYESTER FILM

摘要

Disclosed is a matte multilayer polyester film excellent in contamination resistance, chemical resistance, formability, heat bondability, delustering properties, embossing properties, water vapor barrier properties and the like, which is particularly suitable for wallpapers. Specifically disclosed is a matte multilayer polyester film having at least a two-layer structure of A/B. The polyester of layer A is composed of a composition containing 60-95% by weight of a polyester (a) and 5-40% by weight of an incompatible resin (b), while having a glass transition temperature TgA of 30-70°C. The polyester of layer B is mainly composed of a copolymerized polyester having a melting point TmB of 120-210°C. The degree of surface glossiness of the layer A is less than 50%.
