Abstract
A tape laminate comprising an internally separable layer having first and second opposite major anchor surfaces, which separable layer has an internal static shear strength in a direction parallel to its anchor surfaces that allows it to support a significant weight (e.g., at least 6 pounds per square inch), and has an internal dynamic tensile strength in a direction generally normal to its anchor surfaces of no greater than 40 pounds per square inch. The major anchor surfaces of the separable layer are bonded to the opposed surfaces of objects (which bonding can be done with strips of stretch release adhesive) so that the laminate can support one object from the other against a static force generally parallel to said anchor surfaces of at least 6 pounds per square inch, whereas the separable layer can be internally separated by a dynamic separating force normal to said anchor surfaces of no greater than about 40 pounds per square inch to separate the objects.
