    摘要: There is disclosed herein a refrigerant container in the form of a bag, or pouch, made from two sheets of multi-layer barrier film material which are heat sealed adjacent their edges to form a closed pouch which has an interior space. The bag may be connected to an access valve provided in a line of a sealed refrigeration system for capturing the refrigerant therefrom. The barrier film material is specially formulated to prevent outward permeation of a refrigerant and to prevent inward permeation of air. A valve stem is provided for filling and emptying the bag.
