Torque Recommendations for Bottle Capping

Torque refers to the rotational force used when applying or removing a cap from a bottle.

Application Torque:
This is the rotational force applied when a cap is tightened onto a bottle. It directly influences the seal’s security and the tightness between the bottle and the cap. Achieving the correct application torque is essential for maintaining the seal’s integrity, ensuring it can withstand expected conditions such as changes in temperature, humidity, or exposure to shocks.

Removal Torque:
This refers to the rotational force required to unscrew or remove a cap from a bottle. It determines the amount of force needed to open the packaging. A well-designed package should have a removal torque range suitable for its intended use, factoring in the requirements for features like child-resistant or tamper-evident closures.

Stripping Torque:
Stripping torque occurs when the applied torque is excessive, causing the cap or bottle threads to distort or misalign. This can result in a loose cap, a poor seal, or even damage to the packaging components.

The following torque values are listed for use as guidelines only and are to be used for closure application by hand under controlled conditions. We recommend testing with your equipment to determine the correct setting to suit your requirements.
