What Is Spiral-Wound Paper Tube?
Spiral-wound paper tubes explained for buyers: ply build, crush strength, ends, and converting notes. Use specs—not catalog photos—before RFQ.
Quick answer
A spiral-wound paper tube is built by winding paper plies at an angle around a mandrel, then bonding them into a cylinder. Buyers use it for posters, cores, and industrial packs where crush strength and wall thickness matter more than decorative can aesthetics.
How is it different from a composite can?
Tubes focus on wall crush and length; composite cans add barrier liners, rims, and sealed ends for retail fills. Do not copy a tube wall spec onto a food-can RFQ.
What specs control performance?
ID/OD, wall thickness/plies, paper grades, adhesive, and end closures drive ovalization and crush. Humidity and packing method change usable strength in export lanes.
RFQ language
ID/OD/length; wall plies/grade
Crush target; end plugs/caps
Print/wrap; humidity route
Sample tubes; monthly volume
What else should buyers check?
Ask for crush method, moisture limits, and retained samples from the production lot—not only a cut wall sample from showroom stock.
