Locating small breaches in the material itself.
This bubble emission method is excellent for go/no-go testing of gross leaks, but it has limitations. Do not use it for:
Fill the vacuum chamber with the test liquid (water + 0.05–0.5% non-foaming surfactant). astm d3078 pdf 2021
Holds the flexible package fully submerged under the water line.
The ASTM D3078 standard covers the determination of the presence of bubbles in sealants, including adhesives, coatings, and other materials used for sealing joints and surfaces. The test method involves applying a sealant to a substrate, curing it under specified conditions, and then examining the sealant for bubbles. Locating small breaches in the material itself
Isolated bubbles clinging to the outer surface of the packaging package upon submersion are normal and do not indicate a leak. Applications Across Industries
As the chamber pressure drops, the internal pressure of the flexible package becomes significantly higher than the surrounding liquid pressure. Holds the flexible package fully submerged under the
While highly effective, it cannot reliably detect ultra-fine micro-leaks (less than 10–50 microns) that advanced tracer gas methods can find. Practical Applications across Industries Typical Packages Tested Primary Objective Food & Beverage Snack pouches, coffee bags, meat trays, cheese wrappers Prevent oxygen and moisture ingress to stop spoilage. Pharmaceuticals Blister packs, pill pouches, liquid sachets
