Paper Tubes. It’s what we do.

Last year, we set out to educate as many people as possible by launching our Knowledge Base.

We had noticed that many of our clients, packaging distributors, curious minds, builders, crafters, retail shop owners, tape and label makers, printers, freight companies, artists, architects, poster companies, etc. all seemed to be asking us the same questions.

Although paper tubes are structurally the same (they all look like a toilet paper tube, with a twirling seam), they’re used in a variety of applications. And depending on how the paper tube was being used, we were able to predict what questions might be asked by somebody in that field.

For that reason, we created our Knowledge Base – a collection of paper tube-specific articles, Q&As, and other helpful information.

For example, an artist who designs and ships custom posters on Etsy will have questions specifically related to packing and shipping poster tubes.

Are "cardboard tubes" really made with cardboard?


No. Paper tubes are made with "plies" or layers of paper, not cardboard.

Paper tubes are referred to as "cardboard tubes" so often that most paper tube manufacturers usually will not correct the incorrect terminology.

Can you Match our Company Logo Pantone color

Yes. When providing your art, be sure to specify which Pantone number(s) you want used.

Pantone matching is available for all of our "labeled" products.

Our "labels" are printed C2S sheets with an aqueous coating, trimmed to fit the size of your custom tube. If you do not need Pantone colors matched, CMYK labels will be printed.

How do I measure a paper tube or paper core?

Paper tubes and paper cores have 4 parts:
1. Inside diameter
2. Wall thickness
3. Outside diameter
4. Length

Diameter

Definition: a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.

1. Inside diameter

Imagine yourself looking through the inside of a wrapping paper tube. The circular end that you're looking through is the inside diameter. Inside diameter is often abbreviated "ID". It can be measured with a ruler, but for a more accurate measurement, tools known as calipers or micrometers should be used. The ID is measured from the inside of one side of the tube to the inside of the other side of the tube. Remember, only measure the inside of the hole.

2. Wall thickness

Paper tubes are made up of multiple plies, or layers, of paper that has been glued together. The wall thickness is the thickness of all of the plies of paper glued together. The wall thickness is always consistent all the way around the tube.

3. Outside diameter

The outside diameter is the total distance from one side of the tube to the other side. Outside diameter is often abbreviated "OD". If you know the ID and wall thickness, you can calculate the OD like this:
Example:
ID = 3"
Wall thickness = .125"
ID + wall thickness + wall thickness
3" + .125" + .125" = 3.25" OD

4. Length

The length of a paper tube or core is how long it is. Because lengths are often much longer than IDs and ODs, a tape measure is the most common tool to measure this dimension. Most paper tubes and cores cut with a saw have a length tolerance that may fluctuate +/- .250". This tolerance increases as the tube length increases. Tubes cut with a circular blade / knife have a much smaller tolerance of +/- .030".

The end use of the paper tube or paper core will determine which dimensions are most critical.
