    摘要: A length of thermoplastic strapping for use as strap disposed in a loop around an article with overlapping strap portions arranged face-to-face and welded together, has a first layer (10) including a first material and a secoind material (12) carried by the first layer (10). The second material (12) ensures the creation of a plurality of cavities or discrete volumes (50) in the first material in the weld. The second material may be a layer of material with pre-formed cavities or may be a particulate foaming agent (12) located on or in the first layer (10). The welded joint from such strapping includes a resolidified region (8) formed by fusing at least part of the thickness of each strap portion. The resolidified region (46) includes a solid phase of the first material and a plurality of discrete volumes (50) defined in the resolidified region from which the fist material is absent and which are distributed in the first material across the width and thickness of the resolidified region (46) at least adjacent each end of the resolidified region (46).

    摘要: An apparatus and method for producing an oriented plastic strap having a predetermined desired thickness for use in strapping packages and the like is passed between a pair of cylinders or rollers placed closely together at a desired nip for reducing the thickness of the sheet. One roller is rotated at a faster lineal rate of speed than the other, and the rollers rotate in opposite directions. This apparatus and method achieves milling and stretching of the material simultaneously substantially at the nip.
