Sterikraft D is a bleached wet strength paper with excellent The packed product can be sterilized by treatment with bacterial barrier properties, suitable as a top web for direct ETO or irradiation sterilization. When using 70 g/m2 paper heat sealing to plastic films. Sterikraft D has a higher seal also steam sterilization can be used strength compared to Sterikraft G, to suite a wider range of films. Approvals Grammages Sterikraft D is produced in compliance with ISO11607-1 60 and 70 gsm and EN868-6. For 70 g/m2 the paper is also produced according to EN868-3. Materials Sterikraft D is produced from pure bleached pulp and Certification consists entirely of primary fibers. These fibers are from Sterikraft D is produced at BillerudKorsnäs Skärblacka, slow growing Scandinavian forest, which gives the paper its which is certified in accordance with ISO 9001, ISO 14001 inherent strength. and FSSC 22000.
