Abstract
A binding strap manufactured by the embossment of a relatively narrow and flat band obtained by the extrusion molding of a starting material consisting predominantly of a thermoplastic synthetic resin having good crystal orientating tendency followed by stretching the so extruded band to a high degree in the extrusion direction, wherein there are present at both the front and back sides of said strap two sets of a multiplicity of parallel grooves, said two sets of grooves obliquely intersecting each other; said grooves at the front and back sides being in register; the state of crystal orientation in the extrusion direction in the grooved portions, which are distributed reticulately over the whole of the strap, being substantially reduced as compared with the other portions.
