Universal PTFE Tape for Vacuum and Impulse Sealers. Fits virtually all vacuum sealers and most hand/impulse heat sealer models. Replaces degraded or burnt-out PTFE tape, a crucial barrier between heating elements and the bag. Old tape causes poor bag sealing and can lead to broken heating elements and a damaged sealer. The tape may be slightly wider and longer than necessary, allowing for broad compatibility. Replace the tape when it looks worn, is discolored, or if the seal is not perfect. Simply peel the tape from the roll and place it in the correct location (you may need to clean the tape before placing the new tape). Over the wire for vacuum sealers, under the wire for impulse sealers. Compared to ordinary tape, this PTFE tape is more heat and cold resistant. It has a good effect in insulation for high voltage; there is no chemical reaction for chemical drugs or agents and solvents; It has resistance to light, oxygen, wear, corrosion, unusual smoothness, good paste ability and other advantages.
