This single-sided 9 mil fabric banner material excels in tradeshow situations where you need a material that will hang flat with no edge curl. This is the best solution for retractable banner stands. No edge trim is needed, and the edges do not need to be finished in any way. Just trim to size. However, the material can be grommeted and hemmed if desired. Optimal heater setting is 37-40 C (104-122 F) depending on environmental temperatures. OMG-TSB9-82-63 Tradeshow Banner 9 mil, 63"X 82'
