Application torque testing for packaging

Introduction to torque testing

Torque testing is a vital part of packaging quality control. It measures the rotational force required to open or close caps and closures, helping ensure product integrity, user safety, and regulatory compliance. In packaging, this often involves static torque testing, where force is applied without ongoing motion, as opposed to dynamic torque, which occurs under motion or vibration.

Common issues such as over-tightened caps causing breakage, loose closures leading to leakage, or child-resistant mechanisms being too difficult or too easy to open can all be identified and mitigated through accurate torque measurement. Testing ensures forces remain within safe and functional limits.

Why torque testing is essential in packaging

Prevents leakage in liquid containers
Ensures seal integrity and prevents contamination
Confirms child-resistant closures are effective and compliant
Improves user experience by avoiding over-tightening

Reliable torque values not only reduce product failures but also protect brand reputation - especially in pharmaceutical, food, and chemical sectors.

Applications of torque testing in packaging

Food and beverage: PET bottles, screw-top jars
Pharmaceutical: Child-resistant packaging, blister packs
Personal care: Tubes, pump dispensers
Chemical products: Industrial containers, tamper-evident closures

Testing child-resistant closures (CRCs)

Child-resistant packaging must comply with strict regulations. Mecmesin’s equipment accurately tests the opening and resealing torque of CRCs to ensure usability and safety.
