Types of Jumbo Bag Construction (U-Panel, Circular, 4-Panel)
If you're in the market for jumbo bags, there is a lot to consider. Top construction, bottom construction, baffles or no baffles, coating or non… the list goes on. However, one of the less considered types is construction. Bag construction refers to the way that the sheets of woven polypropylene are sewn/stitched together to form a bag. There are several different construction types and these types can have a big impact on the SWL (safe working load), industry applications, and safe handling of the bag.
U-panel bags are constructed with three body panels - one that runs the full length of the bag forming the bottom and two sides and two additional pieces of fabric sewn into the larger piece that form the other two sides. Similar to other construction types, the U-panel bags will maintain a square shape when filled, especially a U-panel bag with baffles. U-panel bags are an industry standard and the most popular type of construction offering high safe working loads (SWLs) and solid durability.
Circular bags are made with a tubular piece of fabric that forms all sides of the bag allowing for stitching only for the top and bottom of the bag. Although the fabric is tubular, when filled the circular baffle bag will still resemble a square bag. There is a common misconception with circular bags regarding their shape when filled. They aren't literally circular; they are simply constructed with a single piece of fabric that forms all four sides of the bag. While they still resemble square/rectangular FIBCs, they will hold that shape the least of the construction types when filled.
4-panel bags are constructed with four individual pieces sewn together to form a square structure. When filled, a 4-panel bag will hold its square shape similar to other construction types. Typically, 4-panel bags will hold their shape better than the U-panel bags, and a U-panel bags will hold their shape better than a circular bag. The biggest drawback to 4-panel bags is the large amount of stitching required to keep the bag together. This can allow for more areas of the bag prone to failure. However, 4-panel bags are ideal for storage due to the way they hold their shape when filled.
Any of the construction types listed above are flexible in nature and can bulge at the sides when filled losing their square shape. Baffles are extra fabric panels or pieces of string sewn into each of the bag's four corners. This reinforcement allows the bag to better hold its square shape when filled making them easier to store side by side or stack.
