Ship more efficiently with our 18.25 " white triangle mailing tubes, the faster, space-saving alternative to round tubes. These ECT-32-B corrugated tubes assemble in seconds with locking tabs and no tape or glue required. Bundle of 50 tubes ships flat to reduce storage and transportation costs.
Common questions
Do these tubes require tape or adhesive to close?
No. The one-piece design features integrated locking tabs that securely close without tape, glue, or additional fasteners, saving time and reducing assembly costs.
What makes triangle tubes better than round mailing tubes?
Triangle tubes open along their length for easier packing, reduce dimensional weight shipping charges, pack more efficiently in storage, and minimize product shifting during transit compared to round alternatives.
Is ECT-32-B corrugated suitable for fragile items?
Yes. ECT-32-B (Edge Crush Test 32 pounds per inch) provides strong protection for most shipped items. For extremely fragile goods, consider adding interior cushioning materials.
How do these tubes ship to my facility?
All 50 tubes in your bundle arrive flat-packed, requiring minimal storage space and freight costs. Simply unfold and lock when ready to use, no assembly labor required.
