Common questions
Why are square tubes better than round mailing tubes for shipping?
Square tubes eliminate rolling during transit, providing stability on conveyor systems and reducing packing time. They stack efficiently, maximize carton space, and prevent product rotation that can damage contents.
How quickly can these tubes be assembled?
No tape, glue, or tools required, tubes fold together in seconds. Operators can assemble 300+ tubes per hour, significantly improving packing line efficiency.
What crush strength does ECT-32-B corrugated provide?
ECT-32-B (32 ECT) delivers approximately 32 pounds per inch of edge crush test resistance, meeting ASTM D3786 standards for most commercial shipping applications and fragile goods protection.
Can these tubes accommodate items 25 inches long?
Yes, the 25-inch length accommodates rolled materials, posters, blueprints, and elongated products up to that dimension. Internal diameter is 3" x 3", suitable for items under 3 inches on each side.
