Description

Supply Air Tube Mailers are corrugated cardboard shipping tubes designed to protect rolled documents, posters, blueprints, and artwork during transit. Each tube measures 2 inches in diameter and 24 inches in length, constructed from kraft corrugated cardboard with a circular cross-section. The corrugated construction consists of a fluted inner layer sandwiched between two kraft liner sheets, providing structural rigidity and cushioning against impacts. Each tube weighs approximately 0.15 pounds. The interior diameter accommodates rolled items up to 1.75 inches in diameter when the end caps are inserted. Assembly requires no tape or adhesive — contents are inserted through one open end, then both plastic caps are pressed into place to seal the tube. The brown kraft exterior accepts shipping labels, stamps, and handwritten addresses. Each tube is manufactured in the United States from recycled corrugated material. This listing covers multiple pack quantity options to suit different volume needs.
