Laminated plastic bags with degassing valves keep hygroscopic resin high and dry on ocean voyage
Du Pont satisfies its customers' demands by switching from multiwall kraft bags to high-barrier, laminated plastic bags with one-way degassing valves, which allow moisture, air, and other gases to escape from the bags without letting moisture or air back in.
E.I. du Pont de Nemours & Co. manufactures Selar® pellets, a plastic barrier resin used primarily for molding and extrusion, at Plants in Orange, Tex., and Parkersburg, W.Va.
