4x4x24 Tall Corrugated Boxes – Easy-Fold Shipping Tube Mailers for Posters, Blueprints & DTF Film Rolls (Pack of 30–1000)

Laminated White Tube Boxes Ship long, rolled items without fighting round tubes or taping seams. These 4x4x24" square shipping tube boxes fold into shape in seconds — no glue, no side tape, no assembly. Just unfold, drop in your item, and tape the two end flaps. That's the whole job. Brands packing in volume cut packing time by up to 70% compared to standard tuck-end boxes. Built for what you ship: DTF film rolls and transfer rolls Posters, prints, and artwork Blueprints, maps, and architectural drawings Vinyl, UV stickers, banners, and LED strips Why square beats round: Square tube mailers stack flat, don't roll off conveyor belts, label easily on a flat surface, and pack tighter on pallets — saving storage space and reducing carrier handling damage. Heavy-duty construction: Crush-resistant corrugated board with a moisture-resistant laminated coating that protects contents in transit and gives shipping labels and tape a strong, reliable grip. Arrives flat-packed to save storage space.
