Abstract
A sheetform article such as a binding strap and the like which exhibits improved fusibility is a laminar composite made of a crystalline synthetic thermoplastic polymer. The composite has a major thickness portion or base layer of the polymer having a relatively lower average molecular weight and a minor thickness portion of the same polymer but having a relatively higher average molecular weight. The minor thickness portion defines a fusible face of the sheetform article, and all thickness portions of the article have substantially similar planar crystalline orientation.
