Roll it loosely around a wider inner tube or a rolled sheet of kraft paper, cap both ends, and place the label lengthwise along the tube. A snug roll creases the print, and a label wrapped around the tube can be misread by scanners. Most poster damage comes from rolling too tight, not from the trip itself.
Start with the print facing inward or outward? For most posters, roll with the printed side facing out. That way the paper's natural curl works with the roll instead of against it, and the print does not press against itself and pick up marks. For a glossy or freshly printed poster, roll it printed side in, with a sheet of tissue or kraft paper as a barrier, so the glossy surface does not stick to itself.
Pick a tube a few inches longer than the rolled poster, and wide enough that the roll slides in without force. A narrow tube forces a tight roll, and a tight roll is what leaves a permanent curl and edge creases. A wider tube costs a little more in dimensional weight, but a poster that arrives flat and uncreased is worth it.
Length matters at the ends too. The poster should sit short of both caps, with padding filling the gap, so a dropped tube does not drive the cap into the poster's edge. Crumpled kraft paper at each end does this job well, and it doubles as cushioning if the tube is crushed slightly in a stack.
Wrap the rolled poster in kraft paper or tissue before it goes in. The wrap keeps dust and scuffs off the surface and stops the roll from unspooling when the cap comes off at the other end. For a valuable print, add a clear plastic sleeve as well, which guards against rain if the outer tube gets wet.
Do not tape the poster roll itself. Tape on paper tears the surface on removal, and a taped roll cannot relax when unrolled. The outer wrap holds the roll; tape belongs on the tube caps, not on the print.
| Step | Do this | Why |
|---|---|---|
| Roll | Loosely, around kraft paper, printed side out for most posters | Avoids creases and curl memory |
| Wrap | Kraft paper or tissue around the roll | Stops scuffs and unspooling |
| Tube | Wider than the roll, longer than the poster | Room at the ends protects edges |
| Ends | Crumpled paper padding, then caps taped on | Caps cannot drive into the poster |
| Label | Lengthwise along the tube, barcode flat | Scanners read it first try |
Lengthwise, along the body of the tube, with the barcode flat against the curve. A label wrapped around the tube bends the barcode around the curve, and a bent barcode is a misread waiting to happen. If the label is wider than the tube's flat area, use a longer label pouch or a larger tube: never fold the barcode around the end cap.
Place the label near the middle of the tube, not at an end where caps and tape can cover it. Cover the label with one smooth layer of clear tape, following the length of the tube, so it cannot peel in handling. Tape over a barcode is fine when it lies flat and clear; wrinkled tape over a barcode is not.
It does no harm, but do not rely on it. Handlers see hundreds of markings a day, and a tube is already obviously unbendable compared with an envelope. What protects the poster is the tube wall itself, not the writing on it. If the poster is valuable, a thicker-walled tube or a triangular mailer, which resists crushing better than a round tube, is a better spend than a marker.
Triangular mailers have one trade-off: they are awkward to label, since the label must sit flat on one face. If you use one, check that the full label, barcode included, fits flat on a single face before you seal it.
LetterAgent provides Canada Post Xpresspost labels in Canada, for parcels up to 5 kg, quoted up front and paid once through Stripe. A poster tube fits that shape as long as it stays within the carrier's size and weight limits for the service. Print the label PDF, place it lengthwise on the tube as described above, and drop it off. Check the tube's length against the carrier limit before buying the label, since very long tubes can exceed it.
