摘要：The known paper files of this type, in which the plastic window is formed by a film attached to the inside of the one file cover, cannot be printed or labelled in a copying apparatus since the two materials, namely the paper and the plastic film, behave differently during heating. According to the invention, the window is now not punched out of the file cover, but only bounded by means of a perforation (2a) before the transparent plastic film (3) forming the window is bonded or welded on by its edge region. In this manner, the plastic film (3) remains covered by the paper (2c) which allows the file to be procesd in a copying apparatus. After leaving the copying apparatus, the covering (2c) covering the window can readily be removed along the perforation (2a).闺蜜结婚祝福语
