Vertical or horizontal band sealing machines involves plastic film moving between two endless PTFE (Teflon) sealing bands which are pressed together by heat bars. The heat is transferred through the bands and melts and seals the plastic film. The bands are then pressed together by a chilled bar to withdraw the heat to complete the seal closure.
PTFE Sealing bands are available in the size you require to suit your packaging machine. The seamless endless band provides a uniform thickness giving consistent heat and cooling transfer during the plastic film sealing process.
