Paper cores are strong cardboard tubes or cylinders which are used in
fabric, adhesive, electrical, paper product and converting industries as
a sturdy base around which to wind materials for storage or
distribution. Depending on the intended use of the tubes, paper cores
can be made from heavy-duty thick cardboard for industries such as
fabric and electrical, whereas for toilet paper or paper towels, the
cores can be made from thinner, less durable cardboard or paper.
Made from wood pulp fiber, paper cores can be combined with a variety of adhesives and laminates which give the core properties such as strength, water resistance or heat resistance. Made for a wide range of applications, paper cores come in virtually limitless combinations of diameter, thickness and length. Cores are manufactured to provide stable structure from the inside of a product roll. As opposed to many other paper tubes such as shipping tubes or postal tubes, which are fabricated to be an outer protective layer to objects, paper cores provide support from their exterior. As such, a core has to be able to withstand the pressure of the material which is to be wound around it. Products such as tape, paper, plastic or metal foil are wound tightly around the core. Paper cores are essential in the process of space saving as they are able to be used for electrical wires and similar materials which would take up more space in other methods of storage. Furthermore, they are necessary for keeping materials in good condition, preventing knotting, crinkling and tearing.
For distribution purposes, paper cores are hollow tubes which are able to be fed onto a horizontal pole and then able to be rotated around releasing a desired amount of the rolled material at a time. This is a time-efficient method of retrieving products from a paper core, although it is possible to use paper cores without attaching them to a holder. Many consumer product manufacturers use paper cores to store and hold materials. A few consumer applications include fabric, cellophane wrap, aluminum foil, film, electrical and packing tape, disposable paper products, foam, ribbon, labels and stickers. Industrial manufacturers use cores in specialized converting, slitting and die-cutting applications, often rolling materials around longer lengths of cores and slitting the rolled product into distributable portions. Although plastic cores are available for many such applications, paper proves consistently to be the more cost-effective, practical and environmentally sustainable solution. Paper is by far easier for manufacturers to cut, purchase and recycle than most other materials and is extremely versatile in terms of range of uses and fabrications.
