In the packaging industry, leak detection is a vital part of the quality control process. To meet this essential need, Pacorr offers a highly efficient and reliable Vacuum Leak Tester—a powerful instrument designed to detect seal integrity issues in various packaging formats across industries.
Whether you’re in pharmaceuticals, food and beverage, cosmetics, or industrial chemicals, maintaining leak-proof packaging is non-negotiable. With Pacorr’s vacuum-based solution, manufacturers can test packages for air-tightness and prevent product loss, contamination, or non-compliance.
What is a Vacuum Leak Tester?
A Vacuum Leak Tester is a quality inspection device used to determine whether a sealed product or package has any micro-leaks. The test involves placing a sample under water inside a sealed acrylic chamber and applying vacuum pressure. If there’s a breach in the packaging, trapped air escapes in the form of visible bubbles.
This test method is widely accepted in various industries because it is accurate, visual, and easy to perform. Pacorr’s equipment ensures repeatable results, making it an ideal choice for packaging lines, R&D labs, and QC departments.
Why Leak Testing Matters in Packaging
In today’s competitive market, product safety and consistency define brand reputation. Even a small leak in packaging can lead to:
-
Product spoilage or contamination
-
Shortened shelf life
-
Regulatory non-compliance (FDA, ISO, GMP)
-
Health and safety risks
-
Customer complaints and product recalls
Implementing vacuum leak testing helps prevent these risks and adds an extra layer of confidence to your product delivery process.

How Pacorr’s Vacuum Leak Tester Works
-
Water Filling: The vacuum chamber is partially filled with clean water.
-
Sample Placement: The test specimen is submerged under water inside the chamber.
-
Vacuum Application: A vacuum is created inside the chamber using a built-in pump.
-
Observation: If the package has a leak, air escapes and creates bubbles.
-
Result Analysis: Presence of bubbles indicates a leak; no bubbles confirm packaging integrity.
-
Test Completion: The vacuum is released, and the sample is removed for further evaluation or documentation.
This method, known as the bubble emission test, is both practical and effective for routine inspections.
