A disposable container for shipping a hazardous or ultra-high purity liquid material is disclosed, having a body of substantially vapor-impermeable organic polymer material, such as fluorinataed linear high-density polyethylene, a bubbler tube extending from the top of the container having an open end near the bottom of the container, a liquid level detector, and an outlet tube on the top of the container having an open bottom end near the top of the container. A vapor-impermeable metal coating is provided on the outside of the container by vapor deposition or sputtering. A frangible seal is provided at the top of both the inlet tube and the outlet tube. A metal-coated polymer valve is provided on the bubbler, having vapor-impermeable seals isolating the metal exterior from the metal interior, and also having means for rupturing the frangible seal.
