Abstract
The file folder has two covers (2) and a back (1) for connecting both covers, where the back and the covers are partially provided with a sound-absorbing planar formation that is formed by single-layer coatings, particularly micro-perforated or micro-slotted elements. The sound-absorbing planar formation is formed by multi-layer material combinations, for example protecting layers with greater perforation and in-between lying tissue- or nonwoven layers.
