1. A method of manufacturing an intravenous fluid bag comprising:
heat shrinking a plastic sleeve, which is contiguous with a plastic material forming a primary chamber configured to retain a liquid, over an outer surface of a valve;
wherein, after the heat shrinking, the plastic sleeve holds the valve in place and forms a liquid tight seal around the valve and the valve is in fluid communication with the primary chamber.
