Duffle Top / Spout Bottom

Bulk Bag Depot’s Duffle Top / Spout Bottom bulk bags feature an extended inlet that follows the bulk bag’s dimensions from its top seam. The duffle top funnels materials into the FIBC, while the discharge spout at the bottom quickly funnels dry bulk materials out of the bag. Characterized by the lightweight duffle top that provides a large, accessible opening, these bags also feature four standard or cross corner lifting loops. Offered in U-panel, 4-panel, and circular body configurations, these high-quality bulk bags offer ample solutions for a variety of storage and transport needs.

Specification details for our in-stock bulk bags are outlined below. We offer excellent customer service and same-day shipping to our valued customers. For custom bulk bag requests, please contact our product specialists at (800) 645-3183.
