Abstract
Abstract A sterilizable pouch for holding items during sterilization and for storing such items in a sterile condition following sterilization. The pouch includes a first member and a second opposing member. The first member extends outwardly beyond one edge of the second member to define a flap. An opening is defined between the one edge of the second member and the flap. The remaining edges of the first and second members are sealed to one another to define the pouch. An adhesive backed strip having a removable liner over the adhesive is connected along one edge to the second member adjacent to or spaced from the opening and is dimensioned to cover the opening and the flap when the liner is removed and the adhesive backed strip is pressed against the opening and the flap.
