Seal integrity testing is a crucial aspect of the quality control process in many industries, including pharmaceuticals and food. Proper packaging and sealing are essential for maintaining the safety and quality of these products to prevent contents from leaking, spoiling, or becoming contaminated. Seal testing helps to ensure that packages are sealed correctly and free from defects or leaks.
Seal Inspection
Seal inspection is a critical component of package integrity testing. There are several seal testing methods for inspecting seals, including visual inspection, dye penetration testing, bubble leak testing, pressure decay testing, burst testing, and vacuum decay testing. These are destructive and non-destructive seal integrity testing methods.
By visually examining the seals, inspectors can identify potential issues such as gaps, wrinkles, or misalignments that may affect the performance of the seal. This allows for the evaluation of the seal’s quality without causing any damage to the packaging.
It’s important to note that while visual seal inspection (ASTM F1886) is a non-destructive test, it specifically focuses on visual inspection and does not provide information about the strength or hermeticity of the seals. Additional tests or standards may be required to assess those aspects of the seals. At Oxipack, we use the vacuum decay method (ASTM F2338) to test the seal and the rest of the package of flexible pouches, sachets, containers, trays, cans, bottles, and caps.
The Importance of Pharmaceutical and Food Seal Integrity Testing
Especially in the pharmaceutical and food industry testing the seal of packages is extremely important, as these industries work with fragile products. Let’s explain the importance of pharmaceutical and food seal integrity testing:
- Product safety: A compromised seal can allow air, moisture, and other contaminants to enter the package, which can cause spoilage, contamination, or degradation of the product. This can not only affect the quality and efficacy of the product but can also pose a health risk to consumers.
- Shelf life: The shelf life of a product can be affected by a compromised seal. For example, if a food product is exposed to air, it can spoil more quickly, shortening its shelf life. By ensuring that the seal is intact, manufacturers can extend the shelf life of their products.
- Regulatory compliance: Both the food and pharmaceutical industries are subject to strict regulations and standards that require products to meet certain quality and safety criteria. Seal integrity testing is often a regulatory requirement, and failure to comply can result in fines, product recalls, and damage to a company’s reputation.
- Cost savings: By detecting seal defects early, manufacturers can reduce the risk of product spoilage and waste, which can save money and improve efficiency.
- Customer satisfaction: Consumers expect their food and pharmaceutical products to be safe, fresh, and of high quality. By ensuring seal integrity, manufacturers can meet these expectations and build customer loyalty.
Seal Integrity Testing Solutions of Oxipack
Due to the various types of packaging that can be tested for sealing, different solutions have been developed. The advantage of our leak detection solutions is that we not only test the sealing but also the entire packaging for leaks and defects. The non-destructive method ensures you to return approved packages to the production line, because you do not damage them during testing. By doing so, you can save a significant amount of costs, but there are more benefits to consider. If you would like to learn more about them and find out how quickly you can recoup the investment in our machine, we invite you to download our free white paper.
Oxipack offers a wide range of solutions for testing the seal and the integrity of packaging. Our standard solution is the Stationary Leak Tester, used for pouch seal integrity testing, while also providing information on the integrity of the entire package. In addition, various solutions have been developed for testing rigid packaging, such as the Stationary Leak Tester XS or M, the Can Leak Tester, the Bottle Leak Tester, and more.
With our comprehensive range of solutions, we ensure that different types of packaging cn be effectively and accurately tested for leaks and defects, providing you with necessary information to maintain product quality and safety.
