Abstract
A length of thermoplastic strapping is provided for use as strap disposed in a loop around an article so that overlapping strap portions are arranged in a face-to-face relationship, and an improved welded joint from such strapping is also provided. The weld includes at least part of the thickness of each strap portion forming a resolidified region from a fused state after application of heat. The resolidified region includes a solid phase of the first material and a plurality of discrete volumes defined in the resolidified region from which the first material is absent and which are distributed in the first material across the width and thickness of the resolidified region at least adjacent each end of the resolidified region. The strapping has a first layer including a first material and a second material carried by the first material. The second material effects the creation of the plurality of discrete volumes in the first material in the solidified region as a result of the application of heat and subsequent resolidification.
