CETIE Guide 9
CETIE Guide 9
CETIE Guide 9 is an acknowledged testing guideline, which is applied in the beverage packaging industry to assess the performance of the bottle closures by measuring the torque applied when opening and reclosing. This guide allows manufacturers to evaluate the performance of closures after first use and subsequent reuse of the container, especially for those products that are opened and resealed numerous times. A reliable closure is key to maintaining product quality, ensuring product protection, and providing a pleasing consumer experience. Presto offers advanced torque testing solutions that support accurate and repeatable closure performance evaluation in accordance with CETIE Guide 9 requirements.
Significance
Closure systems must maintain their sealing function not only during the first opening but also throughout subsequent reclosure cycles. Poor closure performance may result in leakage, loss of carbonation, contamination, or shortened shelf life. CETIE Guide 9 is a guide to help manufacturers to measure and monitor the torque characteristics of repeated opening and closing cycles, giving them a great deal of information on the durability of the closure and its functionality. The test data supports product development, closure design validation, process control, and quality assurance activities. Beverage producers, closure manufacturers, and packaging suppliers use this testing method to verify that packaging systems continue to perform as intended throughout their service life. Scope CETIE Guide 9 covers the determination and evaluation of closure torque characteristics during opening and reclosure testing under controlled conditions. The guideline is applicable to threaded closures commonly used on beverage bottles and other consumer packaging containers. It can be used to measure closure retention, resealing ability, and post-use durability. Presto's torque testing instruments provide accurate and repeatable measurements to ensure that the manufacturer obtains their packaging quality and product protection and meets the industry requirement.
