摘要：
A packing band having a superior weld is disclosed. The band can be made of a stretched thermoplastic resin having a flat cross section. The weld is formed by overlapping ends of the band extending in the lengthwise direction thereof. The weld portion of the band includes a plurality of welded sections separated by at least one non-welded section along the lengthwise direction of the band. The welding of the packing band can be accomplished by overlapping parts of the band in a lengthwise direction thereof; melting discontinuous portions of the parts in a pattern along the length of the band parts of a melted portion, an unmelted portion and a melted portion; and then pressing the parts together so that the melted and unmelted portions of the parts contact each other and form a weld.
