Cap torque tester

The cap torque tester is used in the packaging industry to measure the opening or closuring torque of the screwing cap. It is a specific quality control equipment that can be placed on the production line or into the laboratory.

Packaging development

A torque tester[1] is required during the packaging design process.[2] It could be used as a destructive tester to identify if there is any material weakness of the packaging during the screwing process. It also allows to define the torque tolerances of the capping machine. The lower torque limit is considered as the minimum pressure of the cap to avoid any leak of the product. This torque test needs to be combined with a leak test with secure seal analyzer. The higher torque limit is the maximum torque the customer can apply to open or close the product's cap.

Production line control

Once torque tolerances have been defined, the cap torque tester is used as a torque control device on the final product. If the measurement are out of the limits, the capping machine needs to be adjusted. Depending on the production process, it could be necessary to control the opening torque, 24hours after the packaging process. Temperature variations can modify product characteristic with a result of different torque measurement.
