Maintenance 27
Cleaning
The machine will require cleaning occasionally.
1. After daily operation, carefully wipe the sealing cutter clean with a ball of
accumulated scrap sealing film.
2. The machine is not designed or built for waterproof function. When cleaning the
machine, use only a clean cloth, lightly dampened if necessary, to clean exterior
surfaces. Use a ball of accumulated scrap sealing film to clean the seal heads
occasionally as required. DO NOT splash water or other fluids on or into the
machine.
3. Avoid contact with liquid acid or gas, or other corrosives.
Rollers
Make sure the rollers stay clean and grease free. If you should have to clean the rollers,
simply wipe them down with a clean lint free cloth. If a more thorough cleaning is
necessary, wipe the rollers down with a mild detergent and water and let dry. DO NOT
splash water or other liquids into the machine. Never use harsh or abrasive cleaners
or chemical agents when cleaning this machine.
Replacing the Seal Band, PTFE Tape, or Seal Pads
The seal band, PTFE tape, silicone pads, and ceramic beads wear through normal use,
and occasionally it will be necessary to replace them.
Making a good seal depends on three factors:
1. Heat: the temperature of the seal band when energized.
2. Time: how long the seal band is energized.
3. Pressure: how much pressure is applied between the upper and lower seal pad.
If after verifying the factors that affect heat and cycle timing (Aligning the Seal Head
Limit Switch and Actuator and Seal Time, Take Away Time, and Energizing Seal Band
Time settings), and the following symptoms are observed:
• Gaps in the seal
• Weak Seals
• Improper film cutoff
• Excessive sealing pressure required to make the seal
The seal band, PTFE tape, and silicone pad or ceramic bead should be inspected and
replaced as necessary.
