Abstract

The invention relates to a material layer of soft paper, polymer fibre or polymer film intended to be used as a separate layer, or in at least one layer to be placed loosely on, or be bonded to one or more material webs for achieving a controlled diffusion capacity of a liquid deposited on at least the material layer, or for achieving a bulkier and thicker material web. The layer (1) has a plurality of slit formations (2) extending over it, which are laterally arranged in optional and mutually spaced relationship, such as to form free, separate strip formations (3), the layer (1) being intended to constitute a separate material layer or be included in a combination of at least one further, differing material layer or web, which, when the slitted layer (1) is drawn apart to a greater or less extent, positionally fixes the layer in different, given, opened-out configurations, depending on its field of use, this operation resulting in different opening widths being obtained for the slit formations (2) in the material layer.
