Tips to help solve common sealing problems
Enercon induction cap sealers are designed for reliable and trouble-free operation. Once you've setup your system and achieve that perfect seal, every container will seal consistently given no variable in the process changes.
What if you are not getting a desirable seal? Induction sealing is affected by these variables: air gap, line speed, power output and cap application torque. The table below details common sealing problems and tips to solve them. Our General Principles links on the technical support home page contains links to other documents which address the variables of induction sealing.

Burned cardboard liner
- Excessive power from sealer: conveyor set too slow, power set to high.
- Bottle backup under sealing head.
- Insufficient cap application torque
Cap extremely difficult to remove (2-piece liner)
- Insufficient power from sealer:conveyor set too fast, power set too low (insufficient wax melt).
- Improper coil height, coil too high.
- Excessive cap application torque.
- Foam liner polymer welds to polymer in induction liner.
Insufficient sealing power
Metal guide rails located too close to sealing head. Guide rails under sealing head should not be metal because they can distort the electromagnetic field.
Low or no removal torque
- Insufficient cap application torque: closure not securely applied.
- Excessive application torque: threads of closure stripped.
Excessive power from sealer: conveyor set too slow, power set too high.
