CETIE Guide 3
CETIE Guide 3 is a recognized testing guideline used in the packaging and beverage industries for evaluating the bridge break torque of tamper-evident closures. Tamper-evident bands and bridges will make it easy to see whether a package has been previously opened. The guide describes a consistent approach to measuring the breaking torque of the bridges between the tamper-evident band and the closure on first opening. This measurement helps manufacturers verify that closures provide both product security and user-friendly opening characteristics. Presto offers advanced torque testing solutions that allow accurate assessment of bridge break performance in accordance with CETIE Guide 3 requirements.
Significance
Break torque of bridges is a significant quality parameter, influencing package security, closure functionality, and consumer perception. If the bridge strength is not high enough, the tamper-evident properties might be destroyed in transport or handling. A strength that is too high may cause the consumers to encounter problems in opening the package. CETIE Guide 3 aids manufacturers in deciding if tamper-evident closures are compliant with their performance criteria and balance security and ease of use. Test data can be used for closure design validation, process optimization, production monitoring, and quality assurance activities. The method is widely used in the beverage, food, and pharmaceutical and personal care packaging industry to ensure product integrity and customer confidence. Scope CETIE Guide 3 covers the determination of the torque required to break tamper-evident bridges on threaded closures during initial opening. The guideline can be used on plastic and plastic composite caps with tamper-evident bands or rings. Test results may be utilized for routine quality control, product development, packaging validation, and supplier qualification. Presto torque testers provide reliable and repeatable measurement results to ensure that the packaging manufacturer can check the closure action of the packaging and ensure the packaging quality.
