Quality sterilization pouches should be constructed of medical-grade surgical Kraft paper (basis weight range 60g) and a transparent 2-mil polypropylene/polyester laminate film. A tinted film is preferred because the tint allows any compromises in the film's integrity to be more readily visible. The preferred pouch design should be of multiple side and end seals with a self-sealing adhesive strip that MUST adhere to both paper AND film during closure; i.e., 50% paper, 50% film with a perforated fold. The combination of an adequate width self-sealing strip and a perforated fold allow for a clean, uniform fold and seal, thereby creating an EFFECTIVE seal. This is critical to maintaining sterility of the contents until ready for use. The correct method for removing the contents from a pouch is to separate the film from the paper, NOT to push the contents through the film or paper, thus rendering the contents non-sterile.
