The Pioneer of Modern Leak Testing

Flexible Packaging Leak Testing

(Chinese Translation)

Package testing is essential for ensuring integrity during packaging development, machine setup and quality control.

Pin holes, channel leaks and improper sealing all present challenges for leak testing in flexible packaging. The Uson Qualipak tester helps our customers perform clean, dry, non destructive and non subjective leak testing on a variety of flexible package types. Other Uson leak testers such as Qualitek mR and Optima vT can help test rigid containers such as bottles and jars. Custom leak test systems for packaging are also available.

At Uson, we provide non-destructive leak testing techniques for pouches and bags for use in the food, pharmaceutical, cosmetic and medical industries.

Optima vT – A versatile and customizable leak tester with up to two channels and eight sensor inputs that supports pressure decay, differential pressure, mass flow and other common tests

Uson Innovative Systems (UIS) – Custom made manual, semi automatic and fully automatic leak test systems and fixtures
