Operating steps:

1. Tear off the plastic film on the label surface of the plastic cup, leaving the glue on the cup.

2. Take an eraser and wipe it back and forth on the rest of the tape.

3. The crumbs falling from the rubber are mixed with the adhesive tape and slowly fall from the cup.

4. After a few minutes of erasing, the adhesive tape falls off completely, and the label paper on the cup is processed.
