With the highest bacterial filtration efficiency (BFE) available, these sterile wraps shield items from both airborne and waterborne contamination. Wraps have outstanding liquid repellency, even to water, alcohol, and iodine. Use with EtO, steam, gamma irradiation, and E-beam sterilization technology. Petroleum free - wraps are manufactured from environmentally friendly cellulose material made from wood pulp which eliminates skin sensitivity issues associated with oily residues inherent in plastic based wrappers. Even texture permits immediate visual detection of small pinholes or tears. Exceptional tensile strength whether wet or dry. Meets flammable fabrics act (FFA) requirements.
