Bottle Cap Torque Tester

The bottle cap torque testing system (open or lock force) is an important facet during PET bottle testing/bottle quality check that is responsible to deduce the sealing performance of a bottle. Excessive torque force while sealing the bottle with its cap would make it difficult to open a bottle – by winding up the bottle cap and could cause inconvenience to the user. Insufficient torque force while sealing the bottle with its cap could cause the container to spill its contents during handling or transportation. Hence, consistent measurements during sealing and control of torque are necessary while closing a bottle to assure it can be opened easily as well as the contents do not spill during handling.

Saicheng NJY Series Torque Testers are designed to measure the open force and lock force of the caps of bottles, spout bags and flexible tube packages.
