VacMaster® Bag Sealer replacement Seal Tape. Seal Tape covers the wires of the seal bar, so the wires don’t come in direct contact with bags. The tape is built to withstand the heat of the seal bar, and ensure a strong seal. Seal Tape may wear out over time, keep backups so your bag sealer never goes down. Easy to install.
