Testing the integrity of package seals helps ensure that the packaging provides required product protection. Sustainable packaging alternatives, lower cost packaging, and variations
in production line sealing parameters are frequently assessed with seal integrity tests.
Maintaining the reliability of package seals is critical for product quality and safety.
Test Description
A sample is placed into the chamber filled with water. Then the chamber is covered with a lid and they are well sealed. Manually open the gas switch so compressed air flows through the venturi tube to provide a vacuum inlet, which is connected to chamber. A gas regulator can adjust the vacuum degree so sample is in a vacuum environment. The pressure difference between inside and outside of sample will cause the headspace gas to escape if there is a leak. The leak is shown by a stream of bubbles coming out from the leak area.
Technical Features
LT-01 leak tester is the manual model developed. It’s an economic, strong and long durable model.
☛To achieve stable vacuum and considering the fact that compressed air is easier to be obtained at user facility, we use Venturi tube for a high level of vacuum up to –90KPa.
☛Strong and clear chamber provided, same type as equipped to our automatic models; Different sizes and shapes could be customized
☛It could be modified to work with vacuum pump, to achieve higher vacuum (for ASTM D4991)
☛No calibration needed
☛No electricity needed
