    摘要: A polymeric film, particularly a polyester film, comprising an essentially unfilled primary layer substrate and a filled secondary layer exhibiting an improved combination of transparency and handling properties. The filler is a mixture of glass and silica particles. The glass particles have a volume distributed median particle diameter of 1.0 to 7.0 µm and are present in the secondary layer at a concentration of 50 to 1000 ppm, whilst the silica particles are present in the range 200 to 2000 ppm and have an average primary particle size of 0.01 to 0.09 µm. The film is suitable for use in a wide range of applications, particularly for information storage and display.

    摘要: The present invention discloses a semitransparent resin container having pearl gray glossiness made of thermoplastic resins prepared by adding 0.01 to 0.9 weight/percent of polymethy pentene to 99.99 weight/percent of polyester resins and further said thermoplastic resins are subjected to biaxial orientation blow molding after molding of preformation. Thus, pearl gray glossiness of a container can be improved and further the strength of said container can also be improved.
