Abstract
A bag assembly (100) capable of withstanding sterilization by gamma irradiation. The bag (100) includes two walls, each wall composed of at least one sheet (176, 178) of a fluoropolymer film, and a fitment (200). The first and second walls are attached to the fitment (200) along one edge (148) of the bag assembly (100) and sealed to each other along a perimeter (142, 144, 146, 147, 149) of the bag assembly (100).
Claims23
An article comprising:
- a bag assembly capable of withstanding sterilization by gamma irradiation, the bag assembly including:
- a bag portion having first and second walls, wherein each of the first and second walls comprise at least one sheet of a fluoropolymer film;
- and
- a fitment including first and second sidewalls extending between opposing end points, wherein a portion of each of the first and second walls of the bag portion are attached to each other along at least a portion of a perimeter of the bag assembly up to the opposing end points of the fitment defining an interior of the bag portion, and wherein each of the first and second walls are bonded individually to one of the first and second sidewalls of the fitment, and
- at least one fitting extending from the fitment, wherein the at least one fitting is in communication through the fitment to the interior of the bag portion.
2 more elements
A method comprising,
- (a) producing a bag assembly by providing at least one sheet of a fluoropolymer film having first and second walls, a fitment including first and second sidewalls extending between opposing end points, and at least one fitting extending from the fitment and in communication through the fitment to the interior of the bag portion;
- (b) attaching a portion of each of the first and second walls to each other along at least a portion of a perimeter of the bag assembly up to the opposing end points of the fitment, and
- (c) attaching each of the first and second walls individually to one of the first and second sidewalls of the fitment to form an internal enclosure, wherein the at least one fitting is in communication through the fitment to the internal enclosure, and wherein the bag assembly is capable of withstanding sterilization by gamma irradiation.
