ASTM D3967

The ASTM D3967 standard focuses on the method for evaluating the tensile strength of plastic closures used in various industries. This standard, developed by ASTM International, provides the essential guidelines for determining the mechanical properties of plastic materials under tension. It is crucial for industries like food, beverages, and pharmaceuticals, where packaging must withstand forces that could affect the closure's integrity.

ASTM D3967 outlines the testing procedure for measuring how plastic bottle closures respond to tensile forces, which are those that try to stretch or pull the material apart. This test helps manufacturers ensure that their closures are strong enough to resist breaking or deforming during manufacturing, transportation, and everyday use. Proper tensile strength is vital in maintaining the security of the product inside, preventing leaks, contamination, or packaging failure.

To help manufacturers comply with ASTM D3967, Pacorr offers the Bottle Cap Torque Tester, a precision tool that not only measures torque but also assesses the closure’s resistance to tensile forces. By using Pacorr’s advanced testing equipment, companies can ensure their plastic closures meet the standard’s requirements, resulting in high-quality, reliable packaging that keeps products safe and intact throughout their lifecycle.
