Abstract: 1. Adhesive fastener and diaper having such an adhesive fastener. 2. An adhesive fastener, consisting of at least one plastic material, having a plurality of hook means which are integrally connected to a substrate (10), each in the form of a stalk part (14) which is provided with a head part (12) and which protrudes above the substrate (10), is characterized in that at least a portion of the plastic material used is biodegradable and/or is bio-based.

Abstract: A body is claimed that consists of at least two components, of which one component is a carrier part (10) having functional elements (12) protruding from the carrier part (10) and the other component is an elastomer layer (14) that opens out at a surface (16) that protrudes beyond the functional elements (12), which are at least partially embedded in the elastomer layer (14).

Abstract: A fastener part consisting of at least one planar substrate part (10), on one side of which a plurality of mushroom-head-like fastener elements are arranged, each of which, as an integral part of the substrate part (10), has a solid stem part (17) formed in the manner of a rotational hyperboloid and extending along a longitudinal axis, wherein to the free end of said stem part (17) a head part (16) adjoins, the edge regions of which form hooking possibilities and project at least partially beyond the stem part (17), and wherein said head part (16) has a crater-like depression (20) on its upper side, characterized in that a plurality of further crater-like depressions (23) is incorporated into the further side (22) of the substrate part (10), opposite to the fastener elements, in that both crater-like depressions (20, 23) of at least some of the fastener elements extend concentrically or mainly concentrically to the longitudinal axis of the respective assigned stem part (17), and in that the respective further

Abstract: A fastening system is disclosed, which can be applied repeatedly to third components, preferably having a smooth surface, for the purpose of detachable fastening to the same, consisting of at least two interconnected functional parts (2, 6) of planar shape, of which at least one functional part (2) has the form of a film and bears information and at least one further functional part (6) has a plurality of individual elements (4), the free end faces (8) of which adhere to the surface of the respective third component by means of adhesion.
