The work aims to solve the sticky problem caused by the poor anti-sticking properties of paper transferring structure in the bottomless adhesive label printer. Considering the material for the paper passageway and the rubber roll, a variety of materials such as silicone rubber, PTFE, silicon oil paper, PP/PE mixed plastic, PE plastic, glass paper, OPP and OPC mixed plastic were selected and tested for anti stickiness property, so as to select the suitable material for the no backing sheet portable thermal printer. By testing the contact angle, roughness and peeling force of the material at room temperature, and comparing and analyzing the relationship with the anti sticking property, the evaluation of anti sticking performance for these materials was obtained. Silicone rubber and silicone paper had better anti sticking properties, compared with PTFE, and had contact angle above 110° and the peeling force below 0.16 N. However, considering the surface strength and service life, the silicone rubber is more suitable for the paper roller and paper passing material for the no backing sheet portable thermal printer.
