Cap/Closure Torque Strength Testing for Beverage Bottles

Product catalog summary

Introduction
Mineral water, carbonated soft drinks, and alcoholic beverages are typically packaged in various sizes of plastic (PET) bottles. It is crucial that the caps on these bottles are easy to open while being tightly sealed to prevent leakage. To ensure packaging quality, beverage manufacturers must test their bottles for compliance with both domestic and international standards.

International Standards
The document references several international standards for torque testing of bottle caps:

ASTM D2063: Standard Test Methods for Measurement of Torque Retention for Packages with Continuous Thread Closures Using Non-Automated (Manual) Torque Testing Equipment.
ASTM D3198: Standard Test Method for Application and Removal Torque of Threaded or Lug Style Closures.
ASTM D3474: Standard Practice for Calibration and Use of Torque Meters Used in Packaging Applications.

Apparatus
The recommended apparatus for torque strength testing of bottle caps is the Labthink NJY-20 Digital Torque Tester. This instrument is suitable for measuring both the open and close torque strength of bottle caps. Key features include:

Portable design for use on production lines or in laboratories.
Real-time display of peak values on an LCD screen.
High accuracy with test results up to 1% of reading and high resolution of 0.001Nm.
