The seal strength is a decisive factor in the packaging of medical and sterile products. A reliable seal seam stability test ensures that the packaging does not fail under sterilization conditions and during transport, but at the same time is easy to open when it is needed in use.

Why is seal strength important?

The seal seam of medical packaging has two main tasks: It must form a barrier against germs and must not open during storage of sterilized instruments. At the same time, it must be easy to open if necessary so that medical professionals can access the sterile instruments quickly. A defective seal seam could lead to contamination of the sterilized products, which could have serious health consequences.

Standards and test methods

There are various standards for testing the strength of sealed seams, including ASTM F88/F88M and DIN EN 868-5. These standards define the procedures and requirements for testing. For example, ASTM F88 describes the method for determining the force required to open a sealed seam. Samples of the sealed seam are pulled to a certain speed in a pulling machine in order to measure the opening force.

Carrying out the seal seam stability test

1. The test process involves several steps: Sample preparation: strips are taken from the sealed seam, typically 15 mm wide.

2. Tensile test: These strips are clamped in the jaws of a tensile machine and pulled apart at a defined speed. The force required is recorded.

3. Analysis: The results are compared with the specified standards to ensure that the seal seam meets the required standards.

Advantages of regular seal seam testing

Regular seal testing offers numerous benefits that go beyond simple compliance and play an essential role in quality assurance and risk management.

• Safety: It ensures that the packaging provides the required protection and that the sterility of the products is maintained during storage.

• Compliance: It meets legal requirements and standards, which is particularly important for audits and regulatory authorities.

• Quality assurance: It contributes to the continuous improvement of quality management and hygiene processes.

Conclusion

The seal strength is an indispensable part of quality control for medical packaging. The safety and effectiveness of sterile packaging can be ensured by complying with the relevant standards and carrying out regular seal strength tests. Practices and clinics should use reliable service providers to continuously check and improve their packaging processes.
