The strap coil 11 comprises a number of layers of a resin packaging strap 11a wound helically and corelessly around a hollow 11b defining the axis of the strap coil 11. The strap 11a is made of a thermoplastic resin at least on its external surface. In the strap coil 11, a plurality of perforations 11d are pierced in the vicinity of an innermost end of the strap 11a through to a plurality of laminated layer. Each perforation 11d provides a melt-bonded area 11e along its periphery to bond the laminated layers of the strap 11a together. |
