1. Introduction:
A torque tester is a precision instrument used to measure the rotational force required to open or close caps and closures on containers. It ensures product integrity by maintaining consistent torque values, which are crucial for safety and quality.

2. Importance in Packaging:
In industries like food, beverage, pharmaceuticals, and cosmetics, proper torque prevents leakage, contamination, and user discomfort. Under-torquing may result in loose seals, while over-torquing can damage caps or containers.

3. Benefits and Applications:
Torque testers help manufacturers validate packaging quality, comply with industry standards, and avoid customer complaints. They are essential during production, quality control, and R&D to enhance product reliability and packaging efficiency.
