BACKGROUND
Air seal (induction/pressure seal liner) is used under the bottle cap to prevent leakage, contamination and maintain product shelf life.
CHALLENGE
- Insufficient tightening leading to improper liner compression causing leakage and loss of product integrity.
- Excessive tightening force that can damage the liner, deform the cap threads or crack the bottle finish.
- Variation in torque application leading to inconsistent sealing performance
- Maintaining optimal contact pressure on the liner for the long term seal performance.
Failures in the field leading to returns, brand damage and increased costs.
