Paper tubes, also known as cardboard tubes, are cylinder-shaped components that are made with cardboard. Paper tubes can be used for a wide range of functions. Typical paper tube applications include shipping and mailing, cartridge fabrication, crafts, concrete pillar construction, structural support (posters, paper towels, etc.), storage (documents, art, food, etc.) and gardening pots.
Production
Paper tube production starts with manufacturers cutting large sheets of paper or cardboard into thin ribbons. From there, they give the ribbons an adhesive coating and wind them straight or at an angle around a mandrel configured into the designated shape. The majority of cardboard tubes are spiral-wound. Manufacturers can add multiple layers during this step, depending on the tube’s desired level of fortitude. All paper tubes are measured and labeled according to their interior dimensions.
Materials
Paper tubes are fabricated from wood pulp in the form of cardboard, recycled paper, waterproof/water resistant cardboard, paper-adhesive composites, kraft paper, paperboard, and fiberboard.
Paper tubes offer many benefits. First, they are flexible and strong. Second, the cylindrical shape of the tube enables it to contain items which are preferably not folded, such as artwork, maps, posters, and blueprints.
In addition, they can be easily reused and recycled. In fact, paper tubes are commonly fabricated recycled paper, so they support sustainability two times over. Also, because they are recyclable, paper tubes are a cost-effective alternative to other materials such as metal, glass, plastic, or wood. Furthermore, cardboard is easier to cut, purchase, and dispose of, compared to most other materials. In terms of strength-to-weight ratio, cardboard is often times favored over plastic and metal because of its light weight and durability. Heavy-duty cardboard tubes are much less prone to denting and breakage, making this type of cardboard ideal for high-impact mailing and shipping applications.
Types
Paper cores are cores that provide structural fortitude to items such as toilet paper, paper towels, rolls of fabric, electrical wires, coin banks, and grease cartridges used for mechanical and automotive applications. Cores like this are usually named after their application (e.g. toilet paper tubes and paper towel roll cores).
Shipping tubes, also known as mailing tubes, are used to ship things that can be rolled up into a cylindrical shape, such as documents, posters, papers, or pieces of artwork. Mailing tubes are designed to shield products from denting, bumping, or breaking while in transit. As such, they are much stronger than other types of containers, including boxes.
Kraft tubes are tubes made from high quality kraft paper. They are very resilient and are capable of enduring the stress and pressure that comes with transit and transportation processes. They are recommended as postal tubes and other types of tubing for shipping and packaging applications.
