Problem & answerI-01
Seal Missing, Incomplete or Failing Integrity Check
Also covers: Critical control point
Likely causes
- Sealer power too low or too high
- Cap torque incorrect (loose cap will not seal)
- Wrong or missing foil liner
- Head height or bottle position wrong
- Conveyor speed wrong for the sealing time
- Dirty or worn induction head
How to fix it
- 1Stop the line as soon as a seal defect is found; do not wait for the next check.
- 2Isolate all bottles since the last good seal check (start-up, last 30-minute check or last changeover, whichever is latest). Treat them as suspect.
- 3Inspect isolated bottles one by one: missing foil, partial bonding, scorched or wrinkled foil, or foil that lifts with the cap.
- 4Check sealer power, conveyor speed and head height against the standard for this bottle, cap and liner.
