CETIE Guide 6
CETIE Guide 6 is an accepted guide for testing to determine the resistance to a vertical load for bottle closures and sealing systems in the packaging and beverage industries. The guide is directed at the measurement of the force that a closure can withstand when axially compressed during filling, capping, storage, transportation, and handling. Stacking loads and mechanical stresses are often applied to bottles and closures during the supply chain, and it is therefore important to ensure the structural performance. CETIE Guide 6 provides a standardized method for assessing the mechanical strength of closure systems and their ability to maintain package integrity. Presto offers advanced compression and force testing solutions that support accurate evaluation of closure performance in accordance with CETIE Guide 6 requirements.CETIE Guide 6
Significance Seal integrity and package failure depend on the strength of the closure to withstand the vertical load. Too much compression can cause the closure to become distorted, damage the sealing elements, or cause the bottle finish to become distorted, which can result in leakage, contamination, or a shorter product shelf life. CETIE Guide 6 assists manufacturers in identifying if closures will be able to withstand the expected handling and storage conditions without compromising the functional performance. The test results support closure design validation, production quality control, material selection, and packaging optimization. Beverage manufacturers, closure suppliers, and packaging developers use this testing method to maintain product quality and packaging reliability. Scope CETIE Guide 6 covers the determination of the compressive force resistance of bottle closures and related packaging systems under controlled laboratory conditions. The guideline is applicable to a variety of closure designs used in beverage and consumer packaging applications. Test results can be used for routine quality checks, product development, performance comparison, and packaging validation. Presto’s force testing instruments provide accurate and repeatable measurements that help manufacturers verify closure durability and maintain compliance with industry quality requirements.
