Most super sacks are specified by dimensions, safe working load, top and bottom construction, liner status, loop style, prior contents, and whether the lot is consistent enough for repeat use.
Specs that matter on every quote
A useful quote starts with the bag footprint, filled height, safe working load, safety factor, top style, bottom discharge style, liner, coating, loop type, and prior contents. Photos of labels and seams often answer questions faster than a written description.
Common footprints include 35 x 35 inches, 37 x 37 inches, 41 x 41 inches, and 42 x 42 inches, but the right bag depends on the material density and handling equipment, not just the outside dimensions.
Top and bottom styles
Open top bags are simple to fill but offer less containment. Duffle tops help control dust and overspill. Spout tops and spout bottoms work well when product flow and metered discharge matter.
Flat bottoms are common for one-way disposal and coarse materials. Discharge spouts are more valuable when the buyer can reuse the bag in a controlled process.
Consistency drives value
A truckload of one clean spec is usually easier to place than a mixed pile of unknown bags. Mixed lots can still move, but the quote depends on sorting effort, contamination risk, bale quality, and freight distance.
Frequently asked questions
How much weight can a super sack hold?
Many industrial FIBCs are built around 2,000 to 3,000 lb safe working loads, but the actual rating must come from the bag label and design, not from appearance.
Are used super sacks reusable?
Some are reusable for appropriate non-food or internal handling applications after inspection. Bags with damage, unknown residue, missing labels, or incompatible prior contents should be downgraded or recycled.
