Instructions for use
See sterilization protocols
(Cf Introduction: Disinfection and sterilization in the field)
To be reserved for large and heavy packages like orthopaedic surgical boxes since it is more resistant and more flexible than crepe paper.
Storage
In a clean and protected area, protected from risks of puncture, dust and humidity.
MSF requirements
Sheets made of non-woven paper are larger and more resistant, and reserved for very large and heavy surgical sets as the external fixator box.
For other indications use the crepe paper, which is cheaper (see related articles below).
