ABSTRACT:
This relates to the sterile packaging of sterile products. A suitable thermoplastic film tube is formed by an extrusion process wherein the resultant tube is initially sterile internally and externally. The shape of the tube is maintained by a gas supplied under pressure, which gas is maintained in a sterile condition. The resultant tube portions, containers or pouches are filled utilizing filling equipment which is disposed within a housing of the sterile gas supply apparatus and is maintained externally in a sterile state by a suitable heater or other external sterilization methods. A sterile product is delivered from a sterile kettle or the like through a conduit to the filling equipment. The conduit and the filling equipment may be internally sterilized by circulating a suitable chemical sterilizing liquid therethrough as an initial part of the product packaging operation.
