Interster Seal Check < Back to overview
Sterilization pouches are made of a medical grade paper and a laminate. This laminate consists of two or more film layers with different melting grades. Upon sealing the sterilization pouch, the film layer that is closest to the paper will melt first and will give an adhesion within the paper, which results in a clear and even seal. Should the other (outer) film layer also melt, the risk of pinholes exists and the pouch will no longer present a micro-organisms barrier.
A good sealing machine is adjusted in such a way that only the interior film layer will melt. Also, the pressure with which the melted film is applied to the paper during the sealing process is essential. If a pouch is not sealed correctly, there will be no bacterial barrier and no sterility.
