Torque: ensuring optimal closure of your packaging

To meet the regulatory challenges faced by manufacturers, Tournaire has been offering UN-approved single packaging since the 1990s. Behind the research into closures and the laboratory testing of our products lies an essential factor in ensuring the protection of your materials: torque.

Indeed, torque tightening is essential to ensure optimal closure of packaging and thus preserve your raw materials. It guarantees the regulatory compliance of UN packaging.

• For UN packaging, the torque values are those used by the independent laboratory certifying our packaging during approval testing.

• For non-UN packaging, Tournaire recommends torque values that ensure optimal performance.

To enable you to close and open our packaging easily and efficiently, we have developed ergonomic tightening nuts.

These nuts adapt to all your needs:

• Closing or opening by hand

• Torque tightening with a calibrated manual torque wrench

• Opening and closing with a calibrated electric screwdriver

• Closing with a nut mounted on an automatic filling line

Torque values adapted to your packaging

In addition, to support you in implementing your processes, a summary document listing torque values by product range is available upon request from our teams.
