Submerge the sealed package completely. Ensure it is fully immersed and free of external air bubbles.

Introduction In the world of packaging integrity, ensuring that a sealed package is free from leaks is not just a quality metric—it is a safety imperative. For industries ranging from food and beverage to pharmaceuticals and medical devices, a pinhole leak can lead to product contamination, oxygen ingress, moisture loss, and ultimately, a costly recall. astm d3078 pdf 2021

One of the most trusted global standards for detecting such leaks is . Specifically, the 2021 edition of this standard introduced critical updates that refine how flexible, porous, and non-porous packages are tested. Submerge the sealed package completely

Apply vacuum gradually to a predefined level (e.g., 25 inHg for most flexible packages) while observing the package. For industries ranging from food and beverage to

If you are searching for , you likely need the official document for compliance, audit preparation, or implementing a leak test protocol. This article will explain everything you need to know: what the standard covers, the key changes in the 2021 version, how to legally obtain the PDF, and how to apply it in real-world testing. What is ASTM D3078? ASTM D3078 is titled: "Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission."

It is a used to detect gross leaks in sealed flexible packages. The principle is simple yet effective: a sealed package is submerged in a liquid (usually water or a surfactant solution), and a vacuum is applied. If the package leaks, bubbles will escape from the defect point.

Hold the vacuum for the specified dwell time (typically 30–60 seconds, but can be longer per internal protocols).
