This design is extremely stable, making it very stackable, and is ideal for products with low bulk densities.

Volume: 20 to 115 cubic feet.
Up to: 1870 lbs.

Polypropylene Bulk Bags is an internally baffled FIBC (flexible intermediate bulk container) with spread strap lift loop design, and can contain 25% to 30% more than a conventional super sack of the same height.
