Duffle Top Bulk bag
The 4 panel bulk bags have seams along 4 separate pieces of fabric that are sewn together to construct the body of the bag; as well as having one top and one bottom panel sewn in. The bags will tend to hold their shape better and are well suited for stacking.
What is a duffle top? A typical duffle top is usually around 30” in height. It is a “skirt” that is sewn to the top of a bulk bag. A typical duffle top will also come with two polypropylene web ties to allow the user to secure the duffle closed. Duffle tops are great for allowing the user full access to the product as well. Duffle top bags can accommodate a wide variety of filling machines and processes. Duffle tops can be added to any bag style (circular, u-panel, or 4 panel).
