A discharge spout on the bottom wall of a collapsible receptacle has an exterior layer which is grounded during the flow of material through the discharge spout to prevent buildup of static electric charge therein. The discharge spout is made from a metalized fabric having a lower layer of fabric. Secured to the fabric layer is an upper film layer. At least a portion of the exposed surface of the film layer is metalized or laminated with foil.
