Spout Top / Flat Bottom

Bulk Bag Depot’s Spout Top / Flat Bottom bulk bags are constructed from 100% virgin woven polypropylene, a flexible fabric designed for storing and transporting dry products and other bulk materials. These durable FIBC bags have a flat bottom and spout tops that are made from UV-treated fabric for controlled material inflow, typically from feeder machinery.

Known for their exceptional value, our Spout Top / Flat Bottom bulk bags offer numerous cost savings, because they do not require specific equipment or multiple workers when handling or emptying bags. Plus, we offer same-day shipping on our stock inventory.

With a U-panel body and optional lifting loops, these bulk bags offer a safe working load (SWL) of up to 3,000 lbs and are offered in a variety of sizes. Specifications for our in-stock bulk bags are outlined below. For custom requests, please contact our product specialists at (800) 645-3183.
