CETIE Guide 1
CETIE Guide 1
CETIE Guide 1 is a testing guide method that is widely used throughout the beverage packaging industry to measure the opening torque of a threaded cap or closure on a bottle or container. The guide defines a testing procedure to determine the torque to pull the closure from the container after application. The opening torque is an important performance factor that directly affects the convenience, integrity of the product, and function of closure. Uniform torque is essential for providing an effective seal but also for easy opening by the end user. Presto's advanced torque testing solutions are designed to assist manufacturers to meet accurate and repeatable closure torque testing as per the CETIE Guide 1.
Significance
Opening torque is important to ensure that the packaging quality is maintained during filling and storage, transport, and consumption. Too much torque can make containers hard to open; too little can lead to leakage, product contamination, or a shorter shelf life. CETIE Guide 1 helps manufacturers evaluate closure performance and verify that application processes produce consistent sealing conditions. The test results support quality control programs, closure design validation, production monitoring, and supplier qualification activities. Opening torque measurements are a critical quality control procedure for industries ranging from bottled water to carbonated drinks, wines and spirits, pharmaceuticals, and food packaging to help ensure packaging performance and customer satisfaction. Scope CETIE Guide 1 covers the determination of the torque required to remove threaded closures from bottles and containers under controlled test conditions. It can be used with many types of packaging systems, such as plastic caps, metal closures, tamper-evident caps, and beverage bottle closures. The guide supports routine quality checks as well as product development activities. Presto's torque testing instruments provide accurate and repeatable measurement results, which allow the manufacturers to ensure the closure performance and assure the packaging quality requirement.
