7.6 Replacing the Sealing Wire
Depending on the specifications of your machine, you can have one of the following (combinations
of) sealing wires:
• Wide seal: one wide sealing wire
• Cut-off seal: one sealing wire and one cutting wire
• Double seal: two sealing wires
• Bi-active seal: one seal bar with a wide sealing wire on both sides
The process of replacing the sealing wires is the same for all types.
