The Ultimate Guide to Shipping & Mailing Tubes for eCommerce Sellers (Poster Tube Guide 2026)
A poster can leave the printer in perfect condition and still arrive with damaged edges or a crease. Choosing a mailing tube starts with the print itself: how loosely it can be rolled, how much room the protective wrapping needs, and how the package will be closed.
For sellers shipping regularly, those details also affect packing time and the range of tube sizes kept on hand. This guide covers the measurements and packaging choices to review before ordering stock tubes or discussing a custom size with Erdie.
What Are Shipping Tubes?
Shipping tubes are cylindrical containers made from spiral‑wound paperboard or fiberboard. Choose the construction and size to suit the contents, closure and handling requirements.
They are commonly used to ship products that cannot be folded or flattened.
Common items shipped in mailing tubes or poster tubes include:
-
Posters and art prints
-
Architectural drawings and blueprints
-
Maps and educational charts
-
Large photographs
-
Banners and signage
-
Textile rolls
-
Promotional displays
Because of their strength and lightweight design, cardboard shipping tubes are widely used by eCommerce sellers, print shops, and manufacturers.
Shipping Tubes vs Mailing Tubes
Suppliers use mailing tube, shipping tube and poster tube to describe overlapping products. The name alone does not tell you whether a particular tube fits your shipment. Compare the inside diameter, usable length, wall construction and closure, then check the package with the product you intend to send.
For industrial roll materials, a paper core has a different job: the material is wound around it. An outer shipping tube surrounds the item. Specify which component you need when discussing a roll-packaging application.
Why eCommerce Businesses Use Poster Tubes
For prints that can be rolled, tubes offer an alternative to flat packaging. Consider the print, packing process and storage requirements when choosing.
1. Accommodates Rolled Prints
A tube allows suitable prints to be packed rolled rather than folded. Confirm that rolling is appropriate for the paper stock, finish and artwork before packing.
2. Match the Package to the Print
Not every print belongs in a tube. If the artwork must remain flat, choose packaging designed to support it in that condition. If it can be rolled, check the fit with the intended wrapping and closures before ordering a large quantity. Comparing complete packed samples is more useful than assuming one package shape is always stronger.
3. Lightweight Packaging
Compare the weight and dimensions of the complete packed shipment when reviewing carrier costs. Packaging weight alone does not determine the shipping charge.
4. Easier Storage
Businesses shipping large quantities of prints often store tubes in compact stacks, saving warehouse space.
Choosing the Right Poster Tube Diameter
Start with a sample of the print and the protective material you plan to use. Roll them together at a curvature suitable for the print, then measure across the roll. Choose an inside diameter that accommodates that wrapped roll without forcing it into the tube.
Poster dimensions alone do not establish the required diameter. Paper stock, finish, the number of prints and the wrapping all change the fit. If you sell several sizes or paper types, test the combinations you actually ship before settling on a stock size.
Choosing the Right Mailing Tube Wall Thickness
Wall thickness is one specification to review when choosing a tube. Erdie's stock Twist-n-Pull® product page lists regular tubes with a .070-inch wall and heavy-duty tubes with a .125-inch wall. Those are product options, rather than universal rules for all posters or shipping conditions.
Tell Erdie what you are shipping, the packed weight and dimensions, and how the shipment will be handled. For a new application, check a sample with the intended contents and closure before committing to production quantities. A wall-thickness range on its own is not a guarantee against damage.
Recommended Tube Lengths
Measure the wrapped roll along its length and confirm the tube's usable internal space with the closures installed. The poster's printed dimensions and the tube's listed length are not enough to establish that fit.
Allow room for the intended protection at the ends, then check that the contents can be packed without pressing against the closures. Confirm how the supplier measures tube length before ordering, particularly when comparing products from different manufacturers.
The Importance of End Caps
End caps seal the tube and keep the product secure during transport.
Two common types include:
Friction‑Fit Caps
These press tightly into the tube and are commonly used for poster shipping.
Locking Caps
Erdie's Twist-n-Pull® system uses reusable plastic end caps. Insert the cap and twist it to lock; twist it to unlock, then pull it out to open the tube. Check the closure as part of the packed sample, alongside the tube size and protection around the contents.
Square vs Round Mailing Tubes
Round tubes and packages with flat sides handle differently on a packing bench and in storage. Those differences are worth considering, but shape alone does not establish how a package will protect its contents.
Compare the specific construction, fit and closure of the options under consideration. For regular shipments, review the complete package with your carrier as well as your packaging supplier. Do not select a shape on the assumption that it will always avoid additional handling charges or outperform another design.
How to Ship Posters Safely
Use these six steps when packing a poster that is suitable for rolling.
-
Place the poster inside protective paper or a plastic sleeve.
-
Roll the print loosely rather than tightly.
-
Insert the rolled poster into the tube.
-
Add protective padding if needed.
-
Secure both end caps firmly.
-
Label the package clearly.
Before dispatch, check that the closures are secure and that the contents are packed as intended.
Shipping Carrier Considerations
Shipping carriers often calculate costs using dimensional weight. Long tubes may be treated as oversized packages depending on their length and diameter.
Before selecting tube sizes, sellers should review the dimensional rules for:
Understanding carrier policies helps businesses optimize packaging sizes and reduce shipping costs.
Custom Printed Shipping Tubes
Many brands use custom printed mailing tubes as part of their customer experience.
Printed tubes can include:
-
Logos
-
Brand colors
-
Product instructions
-
Marketing messages
Custom packaging creates a memorable unboxing experience and reinforces brand identity.
Recycled Content, Reuse and Recycling
Erdie's Twist-n-Pull® tube body is made from 100% recycled paperboard, and its plastic end caps can be reused. Recycled content describes what the tube is made from; recycling instructions depend on the collection program that receives the used package.
Before disposal, check whether the local recycling provider accepts the paperboard tube and the separate caps, and follow its preparation instructions. A paperboard body does not establish that every component belongs in the same recycling bin. Where a tube and its closures remain suitable for another use, keep them together for that purpose.
Frequently Asked Questions About Shipping Tubes
What size shipping tube should I use for posters?
Measure a sample rolled with its protective wrapping, then check the inside diameter and usable length with the closures fitted. Confirm the fit for the paper stock and number of prints you plan to send.
Are mailing tubes better than boxes for posters?
Choose packaging that suits the print. A tube accommodates rolled items; artwork that must stay flat needs packaging that supports it flat. Compare actual packed samples rather than treating either option as universally better.
Are cardboard shipping tubes recyclable?
Check whether your local recycling provider accepts the paperboard tube and the separate caps, and follow its preparation instructions. Acceptance of the tube body does not mean every component belongs in the same recycling bin.
What is the difference between a shipping tube and a mailing tube?
Suppliers use these terms for overlapping products. Compare the inside diameter, usable length, wall construction and closure rather than choosing by name alone. A winding core supports material wound around it; an outer shipping tube surrounds the item.
How thick should a poster shipping tube be?
Choose the wall construction for the application rather than relying on a universal poster-tube thickness. Erdie offers stock regular and heavy-duty options; discuss the contents and handling requirements when selecting between them or requesting a custom specification.
Final Thoughts
Before ordering, gather the dimensions of the wrapped roll, packed weight, expected order volume and closure requirements. For branded packaging, include the printing requirements too. With those details, Erdie can help you discuss stock Twist-n-Pull® options or a custom tube for the job.
