Abstract
A method and system for filling a flexible film bag attached to a face plate with a flowable composition is disclosed. The system includes a chamber for receiving the flexible film bag and a fill tube for dispensing the flowable composition into the flexible film bag, where the fill tube is at least partially disposed in the film bag. The system also includes a first pump in fluid communication with the chamber, where the first pump creates a vacuum between an exterior surface of the flexible film bag and an interior surface of the chamber, such that the flexible film bag expands from an unexpanded state to an expanded state.
