Lanmar #Zone-75 is a custom PTFE zone tape configuration made from PTFE coated fiberglass fabric with high-temperature transfer adhesive applied only along the edges, creating an adhesive-free 0.75” center zone. This design is built for heat sealing equipment that uses a flexible nichrome ribbon wire heating element, where adhesive in the center can interfere with heating, create buildup, or contaminate the seal area.

The PTFE coated fiberglass surface provides excellent heat resistance, non-stick release, and mechanical strength, while the adhesive-free center zone helps keep the ribbon wire contact area clean for consistent sealing performance and longer component life.

Key Benefits

• Adhesive-free center zone helps prevent interference with ribbon wire elements

• Non-stick PTFE surface reduces film and adhesive buildup

• Supports cleaner seals and more consistent production

• Helps reduce downtime and extend sealing jaw/element life

• Edge adhesive provides secure bonding to the sealing surface

Common Applications

• Impulse sealers using nichrome ribbon wire

• Packaging lines sealing plastic bags, pouches, and containers

• Food packaging where clean release and hygiene matter

• Medical and pharmaceutical packaging requiring contamination-free seals

• Electronics packaging such as anti-static bags and component pouches

• Textile seam sealing and bonding operations

• Automotive and aerospace sealing applications (covers, trim, component sealing)
