Seal Integrity Testing: Ensuring Product Quality and Safety

Background:\nTo ensure that products are properly protected during transportation and storage, it is necessary to test the integrity of the sealed packaging. This helps in continuously improving the materials and processes used in packaging. Maintaining a good seal is crucial for the quality and safety of the product. Seal integrity tests are conducted to ensure that the packaging effectively protects the product from damage or contamination in any environmental conditions. These tests help in identifying potential packaging issues and taking prompt action to fix them, ensuring that the product does not suffer any loss or danger during the packaging process. Seal integrity testing is an essential step in ensuring that the product retains its quality attributes and provides the best possible experience for the consumer.\n\nTest Description:\nIn this test, a sample is placed inside a chamber filled with water and the lid is tightly closed. The control unit then activates and starts extracting air from the chamber until a predetermined level of vacuum is achieved. Due to the pressure difference between the inside and outside of the sample, any air trapped inside the sample will be forced to escape, even if there is a small leak. In case of a small leak, gas will be lost from the sample, causing bubbles to rise and exposing the leak. This phenomenon of bubbles flowing can often be observed with the naked eye.
