Abstract: A glue tape cutter includes a cutting table, a press plate, a holding blade, a cutting base, a knife blade and a shaft. The curved substrate is disposed at the bottom of the cutting table and the holding blade is fixed to the cutting table above the curved substrate. The cutting base is rotationally attached to the cutting table by way of the shaft being attached to the lateral covers of the cutting table. The knife blade is attached to the upper part of the cutting base and the holding blades are fixed to the cutting table above the press plate. Once the cutting base rotates, the glue tape can produce an adhered reversed fold part for the user easily tearing up the glue tape adhered to the paper box.
