摘要：
The invention relates to composite thermoplastic polyester films with outstanding transparency, low surface roughness and good machinability. These films contain, in at least one outer layer, 0.1 to 1% of fine particles with a volume median diameter of between 0.6 and 1.5 micrometers. After being metallized, these films produce highly glossy films with a particularly low gloss difference between the 2 faces.
