PTFE Zone Tape

PTFE Zone Tape Introductions

PTFE zone tape is with high temperature adhesive along the edge and leave an adhesive-free center in the middle. The tape is made from woven fiberglass substrates impregnated with PTFE, then process pressure sensitive silicone adhesive along the edge of the tape. 

The adhesive-free center zone minimize the thermal barrier between heating seal part and sealing material, allows for fast heat transfer through the tape, high temperature adhesive offers easy adhesion to the heating element or silicone rubber and eliminates the need for mechanical fastening, thus the tape is perfect for heat sealing equipment which use flexible ribbon wire to help to extend their working lifetime. Coated with PTFE, the tape provides a non-stick surface to sealing parts, polybag just release from the heating wire quickly under high temperature.
