A closure system for any nondiposable item or device requiring high shear strength, and acceptable peel strength, in all directions includes a first closure element having a backing sheet with mushroom-shaped elements fixed to and extending from one side thereof, and a second closure element having a backing sheet with loop elements fixed to and extending from one side thereof. The loops are uniformly, randomly or irregularly oriented for engaging the mushrooms in a variety of random orientations to provide high, comparable shear strength in all directions. The mushrooms are randomly or irregularly oriented depending upon desired shear and peel strength characteristics.

[ What I claim is:] [1.] A secure but releasable closure system for nondisposable articles, the system comprising:a first closure element having a base with mushroom-shaped elements fixed to and extending from one side of the base, the mushroom-shaped elements having semi-spherical heads; anda second closure element having a base with loop elements fixed to and extending from one side thereof for engaging the mushroom-shaped elements to fix the first and second closure elements together, the mushroom-shaped elements being irregular or random distances from each other for engaging the loop elements in various orientations to provide enhanced shear strength in all directions and acceptable peel strength,wherein the mushroom density is between about 256 and 441 mushrooms per square inch, and the loop density is between about 196 and 900 loops per square inch, thereby providing a shear strength of greater than 50 psi and a peel strength of between about 5 and 8 psi.
