Understanding the Vacuum Leak Tester for Packaging 

ال جهاز اختبار تسرب الفراغ للتغليف is designed to detect leaks in sealed flexible packages by observing air or gas escape when a vacuum is applied. This technique relies on differential pressure, where the pressure inside the package contrasts with the vacuum environment in the chamber. If a leak exists, air or product vapor escapes as a visible stream of bubbles.

أجهزة الخلية LT-01 leak tester offers a reliable and economical method to carry out this procedure. It uses a أنبوب فنتوري to create a vacuum up to –90 kPa, which allows for stable and adjustable vacuum conditions without needing an electric power source. It also provides a customizable acrylic chamber to suit different package sizes and shapes.

ASTM Vacuum Leak Test Method and Compliance

To ensure consistent and accurate results, the vacuum leak tester should comply with the ASTM vacuum leak test method outlined in ASTM D3078. This international standard defines how to perform leak detection through bubble emission testing for flexible packaging.

وفق ASTM D3078, here’s how the process works:

• The package is submerged in water inside a transparent vacuum chamber.

• A vacuum is applied, typically increasing at a rate of 1 in. Hg/sec until the target level is reached.

• As pressure decreases, any leak manifests as a continuous stream of bubbles.

• The vacuum is held for a specified time (usually 30 seconds), after which the package is inspected for test fluid ingress.

• Packages that emit bubbles or show signs of internal fluid contamination are considered failures.

This method is effective for identifying pinholes, weak seals, or improper closures that could allow air, moisture, or contaminants to enter the package.
