An attachment/detachment fastening system comprising a backing, an adhesive on one side of the backing, and a weakened joint in the backing whereby the backing is foldable and tearable along the weakened joint. The backing and adhesives for the fastening system are chosen based on the end application. Suitable backing materials include polymers, papers, and metal foils. Suitable adhesives include pressure-sensitive adhesives and heat-set adhesives. The weakened joint may be formed by mechanical means, such as scoring, slitting, or perforating the backing, or by chemical means such as acid dripping or etching. The fastening system of the present invention is useful in various applications, including joining together products for shipping and sale, e.g., attaching a promotional product to a product to be sold, and as tamper-evidence labels. |
