Self sealing pouch is constructed from medical sterilization paper and multilayer barrier films. On the top there is a strong adhesive tape which is used to seal the pouch safely without the sealing machines. There are two sterilization indicators for ethylene oxide and steam vapor processes on the pouch, which will change colours obviously when after the sterilization cycle is finished, and are able to indicate if the sterilization process is enough and distinguish the articles of sterilized and non-sterilized. 57mm*127mm 6400pieces/carton.
