Revolutionizing Leak Detection for Doypacks with Oxipack’s Stationary Leak Tester

Published on
April 1, 2024

Inquiry from a New Factory in Latin America

A packaging engineer from a new factory in Latin America, specializing in tomato-based sauces packaged in doypacks, recently inquired about testing their products for leaks to ensure they are leak-tight. Upon receiving samples, the Oxipack Centre of Expertise conducted tests on the doypacks and pouches filled with sauce.

Challenges with Detecting Micro Leaks

While large leaks were easily detected, the sauce obscured the smaller, micro leaks, making them difficult to identify. However, when testing the empty packaging using the Stationary Leak Tester (SLT), the process proved straightforward. The engineers at Oxipack developed a customized program that enabled the testing of all empty packaging—from the smallest at 5 grams to the largest at 2.2 kg—using the same settings.

Implementation of SLT

Initially, the customer was skeptical about replacing their traditional water bath test method. However, the benefits of using the SLT became apparent quickly. During the onsite installation, the SLT demonstrated its superior accuracy by identifying leaks in packages that had previously passed the water bath test, including both large and micro leaks. These results were traceable back to the production line, providing invaluable insights for quality control.

Transition to SLT and Improved Quality Control

After just two days of training and validation, the water bath method was discontinued. The factory adopted a new protocol, utilizing the SLT for all empty doypacks. This transition has significantly reduced customer complaints about leaky packages and virtually eliminated the production of defective packs.
