In the world of flexible packaging—ranging from food pouches to medical device bags—ensuring package integrity is critical. A small leak can lead to product spoilage, loss of sterility, or premature product failure. , titled "Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission," is the industry-standard procedure for identifying these leaks.
is a standard test method developed by ASTM International that uses bubble emission to detect leaks in flexible packaging that contains a headspace gas. | | Details | |---|---| | Full Designation
The test focuses entirely on identifying (typically larger than 100 microns) in flexible pouches, bags, and blister packs that contain headspace gas. The Vacuum Immersion Phenomenon
| Package Type | Typical Vacuum (mmHg absolute) | Hold Time (seconds) | |--------------|-------------------------------|---------------------| | Flexible pouches (air removal) | 250 – 350 | 30 | | Rigid trays (modified atmosphere) | 400 – 508 | 60 | | Medical device pouches (porous) | 200 – 300 | 30 | | Blister packs (small cavity) | 300 – 400 | 45 | | Heavy-duty bags | 100 – 200 | 60 | In the world of flexible packaging—ranging from food
A vacuum gauge, an inlet tube from a vacuum source, and an outlet tube to the atmosphere are connected to the chamber cover. The inlet and outlet tubes must be equipped with hand valves. Additionally, a transparent plate is attached to the underside of the cover, positioned such that when the chamber is two-thirds filled with fluid, the plate sits approximately 1 inch (25 mm) below the fluid surface.
To maintain compliance, it is crucial to use the authorized and official documentation.
ASTM D3078-02(2021)e1 is a standard test method designed to detect gross leaks in flexible packaging by creating a vacuum and observing air bubble emissions while submerged. This method is essential for quality control in the pharmaceutical, food, and medical device industries, using a transparent vacuum chamber to identify package breaches.
