These 3 x 18-1/4 inch triangle mailing tubes are constructed from ECT-32-B white corrugated board and ship flat to minimize storage footprint. The triangular form folds into shape using integrated locking tabs — no tape, glue, or additional fasteners required for assembly.
The three flat contact surfaces of the triangular profile prevent rolling during transit, making these tubes a reliable choice for posters, blueprints, architectural drawings, fabric rolls, and banners. E-commerce fulfillment centers, print shops, design firms, and retail shipping operations use them for both individual orders and high-volume outbound shipping runs. The white exterior accepts direct printing, custom labeling, and standard shipping labels cleanly.
Tubes are sold in bundles of 50 and ship via parcel carrier. The flat-pack format means bundles stack efficiently in storage until needed, and reordering by the bundle keeps inventory aligned with shipping volume.
