A breathable film having a specific ball-drop impact resistance of more than 100 mm per gram polymer per square meter. The film has a water vapor permeability of at least 1000 g/m2 in 24 hours. The elongation at break of the film in the machine direction is less than 200%.

Breathable film

This invention relates to a machine for the production of a paper web, paperboard web or tissue web, having a roller with a circumferential surface and having an endless belt, in particular a transfer belt, which is wrapped around the circumferential surface of the roller in sections and has a bottom side which in the wrap zone can be brought into contact with the circumferential surface, as the result of which the endless belt and/or the roller provide a storage capacity suitable for accommodating at least in part the fluid which gets into the wrap zone between the bottom side and the circumferential surface.

Transfer belt

An apparatus for treating a fibrous web, in particular a paper, board or tissue web including a press section and a drying section. The press section includes a central roll around which an at least substantially impermeable belt wraps, the fibrous web being removed from this impermeable belt and fed to the drying section. In this case, as viewed in the web running direction, the first drying group of the drying section includes at most three drying cylinders. In the exit region of the first drying cylinder of the first drying group, in which the fibrous web runs off the drying cylinder together with a permeable circulating belt or is removed from the drying cylinder by such a permeable circulating belt, a removal zone to which vacuum is applied is provided on the side of the permeable circulating belt that faces away from the fibrous web.
