ASTM F1886: approval of seal integrity in flexible packaging
An integral part of sterile barrier integrity testing, ASTM F1886/F1886M standard plays a vital role in evaluating the seal integrity of flexible packaging. This method, based on rigorous visual inspection, is a cornerstone in preserving the quality, safety, and shelf life of products.
The importance of visual inspection in flexible packaging
Visual inspection according to ASTM F1886 is specifically designed to identify channels or breaches in the seal with a width of at least 75 μm. This technique offers a probability of detection ranging from 60 to 100%, depending on factors such as channel size, contrast between sealed and unsealed areas, light reflection angle, and materials used in the packaging. These technical details are essential to ensure the complete integrity of the packaging, serving as a primary barrier against external contaminants.
Evaluation and detection: keys to product safety
An essential aspect of the ASTM F1886 method relies on the level of training and experience of the inspector. Conducting these tests under ISO 17025 (COFRAC) accreditation is crucial to maximize their reliability. For effective inspection, it is necessary for the packaging to have at least one transparent side, allowing a clear view of the seal area. The testing method can also reveal variations in the thermal welding process, which may result from changes in process parameters, equipment, or materials. Furthermore, it can signal potential packaging integrity issues after physical performance testing, thus reinforcing product quality and safety.
