Paper Mailing cardboard tubes
Paper mailing cardboard tubes are the most common and most economical mailing cardboard tubes available. They are lightweight, rigid and resist crushing and bending. Paper shipping cardboard tubes come in three main varieties: open-end, snap seal, and telescopic.
Open-End Mailing cardboard tubes – Open-end mailing tubes are usually made of heavy 3-ply, spiral-wound paperboard. Tight fitting plastic caps seal the end of the shipping tube and help provide strength. These caps may or may not be included with the mailing tubes depending on which supplier you choose.
Snap Seal Mailing cardboard tubes – Snap seal mailing cardboard tubes do not use any external end caps. Instead, the ends fold in to seal the tube. Snap seal mailing tubes are quick, easy, and economical, and they do not require tape to keep them closed.
Telescopic Mailing cardboard tubes – Telescopic tubes expand and contract to hold different size documents. They are strong and virtually crush proof. Telescopic mailing tubes generally have metal end caps.
Plastic Mailing cardboard tubes
Plastic mailing cardboard tubes are more durable than paper mailing cardboard tubes. They can be reused many times and are ideal for mailing and storage. Quality plastic tubes are both shatterproof and weather-proof. Plastic mailing cardboard tubes in a variety of translucent and opaque colours and are available in custom sizes.
Mailing cardboard tubes Dimensions
Postal tubes are usually measured in terms of usable space. This represents the inside diameter and the length minus the thickness of the end caps. To find the outside diameter of the shipping tube, add two times the thickness of the tube to the inner diameter. To find the actual length of the mailing cardboard tubes, add the thickness of the two caps to the inside length.
