Method for aseptic filling of pouches

It has been difficult to utilize standup pouches with fitments in the aseptic filling process. In particular, pouches tend to be difficult to sterilize and it has been costly to apply threaded closures to such packaging. Indeed, a cost effective solution for aseptic filling of standup pouches having fitments has been a challenge. The present invention provides a solution in the form of a method for filling an aseptic pouch having the steps of: (a) providing a pouch, the pouch including a body having a plurality of panels coupled together to define a cavity, and, a spout providing ingress into the cavity, the spout having a plug sealingly engaged to the spout; (b) cleaning the external surfaces of the pouch with a cleaning preparation; (c) directing the spout and the plug into an aseptic zone, the aseptic zone having a supply of sterilized gas having a positive flow within the aseptic zone; (d) removing the plug; (e) filling the pouch with a flowable material; (f) replacing the plug on the spout to seal the cavity; (g) removing the spout and the plug from the aseptic zone; and (h) coupling the plug to a cap, and the cap to the spout, whereupon removal of the cap removes the plug, providing cavity access.
