Comprehensive Guide to Bridge Torque and Packaging Testing

Introduction to Bridge Torque

Definition and Importance

Bridge torque refers to the force required to break the bridges or tamper-evident bands on screw caps. Proper bridge torque is critical for maintaining packaging integrity and ensuring consumer safety, particularly in sensitive industries such as beverages and pharmaceuticals.

Applications in Packaging

Bridge torque is essential in packaging applications, notably beverage, pharmaceutical, and consumer goods industries, ensuring product freshness and preventing contamination.

How Bridge Torque is Measured

Bridge torque measurement involves specialised torque testers to quantify the force needed to break bridges. It differs from breakaway torque, which measures the initial torque required to initiate rotation.

Understanding Torque Testing

Types of Torque Testing in Packaging

Torque testing methods include:

Bridge torque testing
Removal torque testing
Application torque testing

Explore these methods on Mecmesin’s closure torque testing page.

Manual vs. Automated Testing Methods

Manual torque testers suit low-volume, intermittent testing, while automated torque testers offer consistency and repeatability for high-volume production.

Tamper-Evident Packaging and Torque

The Role of Bridges in Tamper-Evidence

Cap bridges provide physical tamper evidence by breaking upon first opening. Proper torque settings ensure these bridges function correctly.

Ensuring Customer Safety and Satisfaction

Effective torque testing ensures regulatory compliance, guaranteeing consumer product safety and integrity. See Mecmesin’s child-resistant closure case study for a practical example.

Standards and Guidelines for Torque Testing

Overview of ASTM and CETIE Standards

Compliance with standards such as ASTM D2063 and CETIE guidelines ensures reliability and repeatability in torque testing.

How to Apply These Standards in Your Process

Integrating these standards enhances product quality control and regulatory adherence, directly benefiting consumer confidence.
