Description

Supply Air 1.5 x 18 Inch Round Cardboard Tube Mailers are rigid cylindrical containers constructed from kraft paperboard. Each tube measures 1.5 inches in interior diameter and 18 inches in length. The tubes ship with two plastic end caps that press-fit onto each end to seal contents. The corrugated cardboard construction consists of kraft paper layered in a spiral-wound tube formation. Each tube accommodates rolled items measuring up to 1.5 inches in diameter and 18 inches in length, including posters, architectural blueprints, engineering drawings, rolled textiles, and artwork. The end caps create a closed container by friction-fitting over the tube openings. Available in multiple pack quantities to accommodate different volume requirements. Each tube weighs approximately 0.15 pounds. Tubes are manufactured in the United States from kraft paperboard. The spiral-wound construction creates a rigid wall thickness of approximately 0.08 inches. Interior dimensions remain consistent at 1.5 inches diameter across the full 18-inch length.
