Compatible with virtually all vacuum sealers, including hand/impulse sealer models. Replaces worn or burnt-out PTFE tape, a crucial barrier between the heating elements and the bag. Old tape causes poor bag sealing and can lead to a broken heating element and a broken sealer. Tape may be slightly wider than necessary, allowing for broad compatibility. Replace the strip when it looks worn, discolored, or if the seal isn't perfect. Simply tape from the roll and place on the area (you may need to clean the strip's placement before placing the new tape). Over the wire for vacuum sealers, under the wire for impulse sealers. Compared to regular tape, this PTFE tape is more heat and cold resistant. It offers excellent high-voltage insulation; there's no chemical reaction with chemicals, agents, or solvents; it resists light, oxygen, wear, corrosion, boasts exceptional smoothness, and has excellent adhesion.
