On-Step* Sterilization Wraps features two layers of wrap, thermally sealed along the sides. It delivers the protection of double-wrapping in a single step, in about half the time it takes to wrap or open packages using sequential double wrapping. It is the fast, easy way to ensure that instrument sterility is uncompromised. Microbial barrier protection with POWERGUARD* technology. Available in six grades from H100 to H600 to meet the full range of applications: the higher the number, the stronger the wrap.
