PTFE earns its place in industry for three reasons: nothing sticks to it, it holds up to +260°C continuously, and it is chemically inert. That combination puts it on packaging machine seal bars, bakery oven belts, laminator rollers, fusing presses, screen printing dryers and high-frequency welding dies — anywhere heat and adhesion meet.
Each page below covers one industry: the machines involved, where the PTFE part sits, and which construction suits the duty. If you would rather start from the product, browse the full product range.
Where PTFE Is Used
- PackagingL-sealers, shrink wrappers, blister packers and bag filling equipment.
- Continuous Cooking & Contact GrillingPTFE coated belting for contact grills and continuous cooking lines in food processing.
- BakingTunnel oven belts, reusable tray liners, dough sheeters, bread slicers and packaging lines.
- LaminatingKeeps adhesive and film off the rollers and platens of hot roll, pouch and wide-format laminators.
- Screen PrintingOpen mesh fabric conveyor belts for screen printing dryers, including GORTEF 9002 and 9004.
- Fusion PressingPTFE glass belts for garment interlining and fusing presses.
- Textile IndustryYarn drying, fabric preparation and finishing.
- High-Frequency WeldingThe RF-transparent release layer on high-frequency welding dies.
- Belt Edging & Belt Tracking CordEdge reinforcement and tracking options that keep a belt running straight.
- Fast Food & Food ServiceGrill sheets, oven baskets and belt wrappers for quick service kitchens.
Working From a Machine Rather Than an Industry?
The machine finder cross-references packaging and garment machines by model number and by the OEM part number printed on the worn part, and names the GORTEF product that replaces it.

PTFE coated glass fabric is used throughout baking, food processing and food service, and GORTEF food-contact grades are supplied to FDA and EU food contact standards. Confirm the grade for your line when you request a quote, as not every construction in the range is a food contact grade.
Packaging, by a wide margin. Nearly every heat sealing machine — impulse sealers, L-bar sealers, flow wrappers, form-fill-seal machines and tray sealers — has PTFE tape on the jaw or seal bar as the release layer between the hot element and the film.
Usually, yes. These pages cover the industries we are asked about most often, not the limit of where PTFE is used. If you have a heat, release or friction problem, describe the process temperature, what is sticking and the dimensions involved, and we will tell you whether PTFE is the right answer.
