Lowering pressure around the sample reveals leaks as bubbles or visible product seepage.
Bubble Emission Leak Test
Submerge the package and apply vacuum: escaping bubbles reveal the leak location. Define vacuum and hold time for your package.

Dry Vacuum Leak Test
Without water, vacuum can reveal liquid seeping through a bottle, jar or tube seal.
Altitude Simulation
Simulate reduced atmospheric pressure during air freight or mountain transport.

Leak Testing for Flexible and Rigid Packaging
CDV vacuum chambers support flexible, rigid and thermoformed package formats across multiple industries.
Industries That Rely on Vacuum Leak Testing
CDV vacuum chambers support packaging inspection during incoming inspection, line qualification and routine quality-control activities.
Food & Beverage
Pouches, trays, bottles, vacuum packs and modified-atmosphere packaging.
Pharmaceutical
Vials, bottles, closures and pharmaceutical packaging configurations.
Cosmetics & Personal Care
Bottles, tubes, jars and other liquid-filled cosmetic and personal-care packaging.
Chemical & Specialty Products
Cleaning products, hygiene liquids, fertilizers, agricultural chemicals and other specialty chemical packaging.
Bubble Emission or a Deterministic Method?
Bubble emission locates leaks visually; vacuum decay and HVLD measure physical signals. Select and validate the method for your package. These methods are not interchangeable.
Compare Probabilistic and Deterministic MethodsBubble Emission
- Visual observation
- Can locate a leak
- Useful for routine package QC
- Relatively simple operating principle
Vacuum Decay / HVLD
- Measures a physical signal
- Objective measurement output
- Used in specific CCI applications
- Requires application-specific validation

How to Choose a Vacuum Leak Tester for Packaging
The right package leak testing equipment depends on your packaging format, test objective and quality-control workflow—not only chamber dimensions.
1. Identify the package
Start with flexible pouches, sealed trays, bottles, jars, tubes or other rigid containers. Package geometry, fill product and seal design affect method selection.
2. Select the test method
Choose bubble emission when visible leak-location evidence is needed, or evaluate dry testing for suitable liquid-filled containers. Match the procedure to the test objective.
3. Define the chamber and controls
Check maximum package dimensions, samples per cycle, target vacuum, hold time and operator workflow. Compare CDV sizes and manual, semi-automatic or PLC controls.
4. Validate with your samples
Confirm that the selected configuration and method work with your product, packaging material and acceptance criteria before specifying equipment.
Explore the CDV vacuum chamber models, review applicable test standards, or request an application evaluation.
Technical note: Visual vacuum leak testing is method-dependent; it should not be described as a universal substitute for quantitative or validated package integrity tests.
Vacuum Leak Tester for Packaging FAQ
A vacuum chamber lowers pressure around a package, revealing leaks as bubbles in water or visible product seepage.
ASTM D3078 describes bubble emission leak testing for flexible packaging. Other methods apply to different package formats and test objectives.
Typical leak-test cycles take under a minute to several minutes. Your package and approved procedure determine the hold time; altitude-simulation tests may take longer.
Wet immersion tests generally make the tested package unsuitable for sale. Dry tests may be non-destructive depending on the product and test conditions.
Yes. Atmospheric pressure decreases with altitude, so maximum attainable vacuum and test settings must consider the installation location.
Select a chamber that can hold your largest package with sufficient space around it and consider how many samples you need to inspect during one test cycle.
