They are manufactured according to international standards from medical paper and transparent plastic film. There are large sterilization indicators and they are suitable for steam and ethylene oxide sterilization. The indicators show an abrupt color change and are placed on the paper surface on the side seam, thus ensuring direct visual contact with the indicators and simultaneously with the sterilized material. The paper side is durable, has a high degree of chemical purity, does not leave lint, and its thickness complies with current standards. During opening, the plastic separates perfectly from the paper, without tearing the paper, eliminating the risk of microbes passing from outside to inside, ensuring an aseptic technique for material retrieval. The side adhesive surface is continuous, uniform (3 seals) of maximum strength, so that it does not open from the pressure of the weight of the instruments and does not leave traces when opened. The plastic side is soft and does not wrinkle after autoclaving, it is also extremely durable with resistance to heavy objects. They have a V-seal at the bottom of the pouch, are non-perforated in double packaging (nylon inside – paper outside). All required indications according to standards are written on their outer packaging.
