Induction seal integrity checks for bottles and jars
A good induction seal should be checked with more than a quick visual glance. Practical seal integrity checks help operators confirm that the foil bond is consistent before products leave the line.
Visual inspection
Look for continuous bonding around the mouth, no burnt areas, no loose foil edges and no obvious contamination. A seal can look neat while still being weak, so visual checks should be supported by physical tests.
Peel and leakage checks
Peel checks help confirm bond strength and consistency. Leakage checks are important for liquids, oils, syrups and other products where transit damage or customer complaints would be costly.
Record settings and results
Record power setting, conveyor speed, head height, cap torque, liner type and batch reference. This makes troubleshooting easier after maintenance, changeovers or material changes.
For a faster recommendation, send cap diameter, liner type, container material, bottle height, conveyor details and target output to Lancing UK.

Link each check to an action and a traceable batch boundary.
A check without a defined response can identify a problem without protecting production. State how many packs are affected after a failure, how they are segregated, what evidence is reviewed and who can release the line.
| Visual failure | Stop or hold production, inspect cap/liner/neck condition and verify settings before restart. |
|---|---|
| Peel failure | Compare bond pattern with known accepted samples and investigate torque, contamination, liner or energy. |
| Leak failure | Quarantine the defined interval and review both closure and seal integrity. |
| Missing foil | Check cap/liner supply and prove detection/reject function if installed. |
