Heat Sealing Bands
PTFE (Teflon) Sealing Bands for Packaging Machines
Last updated: February 2026
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.
Custom-Sized PTFE Sealing Bands
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.
The sealing of either a pouched shape or tray shaped package is a critical component of the FORM-FILL-SEALING machine.
Product's packed and sealed in a Vertical the FORM-FILL-SEALING machine's include such items as Frozen Foods, Pet Foods, Chewing Gum, Powders, Liquids and grains such as rise, which are all packed in a standing position so as to prevent spillage.
Frequently Asked Questions
PTFE heat sealing bands are seamless endless belts made from PTFE-coated material, used on vertical and horizontal form-fill-seal packaging machines. They press against heated bars to melt and seal plastic film around products such as frozen foods, pet foods, powders, and liquids.
Heat sealing bands are seamless, endless loops that run between heating and cooling bars on form-fill-seal machines. Heat sealing belts are wider conveyor-style belts used on continuous-motion packaging machines. Bands are typically narrower and used where the film moves vertically or horizontally through a sealing station.
PTFE sealing bands are manufactured to match your specific packaging machine dimensions. The seamless endless band provides a uniform thickness for consistent heat and cooling transfer during the sealing process. Contact GORTEF with your machine make and model for an exact size match.
Band lifespan depends on operating temperature, cycle speed, and the packaging material being sealed. The seamless construction eliminates weak points, extending service life compared to joined alternatives. Regular inspection for surface wear or thickness variation helps determine replacement timing.
