Abstract
Interlocking closure fastening devices having controlled separation characteristics are provided wherein the interdigitating hooks on one side of each closure element are longer, and/or larger than the interdigitating hooks on the opposite side of each closure element. In another embodiment, the controlled separation characteristics are obtained by forming the profile portion of the closure elements from stiffer plastic material. Combination of the two embodiments provides optimum controlled separation characteristics.
