CETIE Guide 2
CETIE Guide 2
CETIE Guide 2 is an acknowledged testing guidance for the beverage packaging sector, which is for assessing the application torque of threaded closures on bottles and containers. This guide will be based on the torque being measured during capping, a key component in ensuring a tight and uniform seal. Closures that are properly applied will function as intended during filling, storage, transportation, and consumer use, but only if they are applied with proper application torque. By following a standardized testing procedure, manufacturers can verify that closures are applied within specified torque limits and maintain packaging consistency. Presto offers advanced torque testing solutions that help packaging manufacturers accurately measure and monitor closure application torque in line with CETIE Guide 2 requirements.
Significance
Torque is a direct factor of package integrity and protection as a function of the amount applied during closure installation. Too low an application torque can result in leakage, contamination, carbonation loss, or decreased shelf life, and too high an application torque can result in damaged closures, bottle finish deformations, or consumer opening difficulties. CETIE Guide 2 provides a structured method for assessing closure application performance and supporting process control. The data collected can be used to optimize the capping process, test packaging designs, ensure production consistency, and enhance packaging quality assurance programs for the manufacturer. It is especially useful for those closure performance-critical packaging applications, such as the beverage, food, pharmaceutical, and consumer product sectors. Scope CETIE Guide 2 covers the determination and evaluation of closure application torque for threaded packaging systems. The guideline is applicable to a wide range of bottle and closure combinations, including plastic and metal caps used in beverage and consumer product packaging. The test results can be used for routine quality control, production monitoring, closure development, and packaging validation. Presto’s torque testing instruments provide accurate and repeatable measurements that support compliance with packaging quality requirements and industry best practices.
