These 3 x 3 x 30 inch kraft square mailing tubes are built from ECT-32-B corrugated board, delivering a rigid protective enclosure for posters, blueprints, banners, and other elongated items. The square profile is the key differentiator: it eliminates rolling during handling and stacking, reducing shifting on conveyor systems and in transit compared to round tube formats.
The flat-pack, one-piece construction makes these tubes well suited for high-volume fulfillment environments, print-on-demand operations, architectural and engineering firms, and retail distributors shipping rolled goods. Assembly requires no tape or glue, allowing packers to move quickly through volume orders without additional materials at the station.
Each tube measures 3" W x 3" H x 30" L interior and weighs approximately 0.37 lbs. The kraft surface accepts standard labels and postage without preparation. Tubes are sold in bundles of 25 and ship via parcel carrier.
