Sterilization pouches are made from nylon, paper, and plastic. These pouches are designed with a blue film and a medical grade paper to allow sterilization, i.e., chemicals, heat, and steam are allowed to perforate through the through the breathable material. As the instrument cools, the sterilization is complete.
 
There are two categories of sterilization pouches…
 
· Self-adhesive pouches
· Heat seal pouches
 
These pouches contain a self-adhesive tape, and allow proper sealing after the material expands and contracts. These bags are made for expansion and contraction through the application of heat and steam and therefore, they should not be re-used. The width of the adhesive strip should be broad enough for proper sealing. It should be sealed as to cover 50% coverage of paper and 50% coverage of plastic.

The sterilization pouches can be customized, and sterilization reels can be cut to fit the medical instruments precisely.
