I. What is a Paper Tube?

Paper tubes consist of paper or paperboard sheet layers wound together to form strong, hollow, and usually cylindrical shapes. The paper layers are laminated or bonded together using adhesives. The wall thickness of the tube can vary depending on the number of layers wrapped during manufacturing.


Paper tubes are also known as paper cores, paperboard tubes, paper cans, fiber drums with paper drum machine, fiber tubes, paper tubing, wound tubes, composite cans, coreboard tubes, and cardboard tubes. While widely used everywhere, the term "cardboard tube" is a misnomer. Cardboard consists of three kraft layers with the central layer corrugated.


II. Paper Tube Types and Shapes

Paper Tube and Core Types

While paper tubes, paper cores and related products are all made from wound plies of paper or paperboard. Paper tubes with paper tube cutting machine or cores can be constructed from one, two or many plies of brown kraft paper or paperboard.


The innermost layer or ply, the liner, and the outermost layer, the wrap, can consist of different materials (foil, film, etc.) or specialized paper. The specialized paper and materials can provide water resistance, graphics or labeling, or a specific color.


The two main types of paper tubes and cores include spiral wound and convolute or parallel wound paper tubes. Convolute wound tubes are used in applications requiring high bend strength, crush resistance and dynamic strength.


A spiral wound tube has the paper ply or plies wrapped around at an angle to the tube's axis. In convolute tubes, the outer two edges of the paper strip are wrapped parallel or at a 90-degree angle to the tube‘s axis.



Paper tubes have thinner walls and are widely used as containers or packaging for products with paper packaging machine.


A paper core is essentially a heavy-walled paper tube. The much thicker wall of paper cores enables their use in winding webs or sheets of flexible material into rolls in converting operations.


Paper machines produce extremely large rolls (also known as machine, jumbo, tambour or mother rolls), which are rotary slit or converted into many narrower smaller rolls on a winder with a paperboard core. Similar jumbo rolls are converted in plastic film, foil, textile and coated abrasive plants.


You will be surprised that not all paper tubes are geared toward packaging applications. Paper cores can be machine elements. Paper cores used for winding large rolls in a paper mill or plastic film production plant are machine elements and require extremely high strength paper cores, which are often convoluted.


Paper cores for retail or small diameter width rolls of adhesive tape, label, foil, paper, tissue or plastic film are a packaging and dispensing product, which can consist of a thinner, spiral wound core.


The paper tube material is rotary or saw cut into paper cans or composite cans, shipping tubes, push tubes, pyrotechnic tubes, display poles, converting cores, concrete piling forms, and other paper tube products.


Large fiber or composite drums and even paper straws are manufactured in a similar winding process. Convolute winders are typically used to make composite drums, which are a more eco-friendly alternative to steel drums. Paper straws are spiral wound at very high speeds.
