Abstract
The present invention relates to: a packaging strap coil and its production method, wherein the innermost strap end is securely fixed to prevent un-winding thereof and the strap can be smoothly drawn out to the innermost end for strap-packaging of an item; a packaging strap coil unit which prevents deformation of the strap coil; and a packaging machine. The strap coil comprises a number of layers of a resin packaging strap wound helically and carelessly around a hollow defining the axis of the strap coil . The strap is made of a thermoplastic resin at least on its external surface. In the strap coil , a plurality of perforations are pierced in the vicinity of an innermost end of the strap through to a plurality of laminated layers. Each perforation provides a melt-bonded area along its periphery to bond the laminated layers of the strap together.
