Industrial packing tape tensioning 50x66 mm, complying with the strictest European safety standards (Legislative Decree 81/08). Both the outer roller bearings under the knife cuts are covered with a soft rubber and plastic structure treated with electrostatic material that helps to hold the tape under the blade. The sealing of the tape up to the cutting area protects the user as it is not forced to pinch the blade that cuts the tape. Patented.
