4 Panel

The popular Four-Panel Super Sack container is our original polypropylene design and has become the industry standard by which others are judged. The versatile, cost-effective four-panel construction is excellent for a variety of applications and is available custom designed or from our in-stock selection. The U-Panel variation consists of two side panels attached to a ‘u-shaped’ single piece ‘side-bottom-side’ unit.


Volume: Two to 120 cubic feet.

Up to: 4,400 lbs.


The four-panel and u-panel construction has unique glued hems on all side panels, reducing strength loss and sifting from sewing lines (Mexico and Domestic Super Sack containers only). Fabric edges are turned to the outside to reduce potential contamination.
