12. The system of claim 11, wherein the flexible packaging sleeve comprises a plastic bag that is sealed at a distal end opposite the one end, the bag having a bunched up form along the tubular sleeve.

13. The system of claim 11, further including a robotic gripper that moves along a guide track, the robotic gripper including a pair of grippers that are actuatable and move between an open position in which the packaging sleeve can be received between the grippers and a closed position in which the packaging sleeve can be captured between the grippers and a prescribed movement of the robotic gripper causing a predetermined length of the packaging sleeve to be unfurled from the tubular sleeve.

14. The system of claim 13, wherein the guide track is a track and the robotic gripper moves between a first position where the packaging sleeve is captured between the closed grippers and the prepared medication can be inserted into the packaging sleeve and a second position where the packaging sleeve is unfurled the predetermined length to allow sealing of the prepared medication and supplies within the packaging sleeve.

15. The system of claim 11, further including a controller that calculates a length of the packaging sleeve that has been removed and a length of the packaging sleeve that remains on the tubular sleeve.

16. The system of claim 11, further including an automated heat sealer that includes a first part and a second part, wherein at least one of the first and second parts includes a heated element that forms at least one heat seal in the packaging sleeve resulting in the prepared medication being sealed packaging sleeve.

17. The system of claim 16, wherein the heat seal comprises a pair of spaced heat seals and the system further includes an automated cutter that includes a blade for cutting the sealed packaging sleeve between the heat seals resulting the enclosure with the sealed item being cut loose from remaining packaging sleeve and creation of a new free sealed end of the packaging sleeve that is available for extension, wherein the first part serves as a back support surface onto which the packaging sleeve is compressed by both the second part that contains the heated element and the blade during a cutting action after the heat seal has been formed.

18. The system of claim 1, wherein the first stage includes a first automated robotic device and the second stage includes a second robotic device that is in communication with the first robotic device to permit integration of the two stages.
