Where are Paper Cores Used?

A paper core uses a different manufacturing process than traditional paper. Although paper core is manufactured from wood just like regular paper, the manufacturing process is different. Industrial paper cores are made from wood pulp and provide additional stabilization from the inside. These cores are ideal for holding the weight of the object wrapped around the core, such as large amounts of plastic sheeting, tape, or fabric. You can find paper cores used in the following areas:
Tape: When tape is manufactured, it is first wound around a long tube, sometimes longer than 20 feet. The weight of such a large amount of tape, especially heavyweight tapes like duct tape and packing tape, can crush a weak core. Manufactures use heavyweight wood pulp cores to keep the core from collapsing. After rolling, the tape is then cut into smaller segments, which relieves some of the pressure on the interior core.
Plastic sheeting: Plastic sheeting is manufactured and rolled onto large paper cores. These cores must be able to support the weight of hundreds of pounds of plastic, so they cannot be lightweight or the core would collapse. Stronger wood pulp cores are ideal for plastic sheeting.
Fabric: Fabric is surprisingly heavy, and wood pulp cores are ideal for supporting the heavy weight of large fabric rolls. Some fabric rolls can weigh over 400 pounds, which requires the internal core of the roll to have substantial support to prevent collapse.
Paper rolls: Paper rolls are often incredibly thick and heavy. Some paper rolls are several feet wide, which can place significant weight onto the internal core. The core must be strong enough to withstand the heavy weight of the paper so that the paper maintains its shape without creasing.
Thick, sturdy paper cores are used in all of the above applications and more. Next time you purchase an item on a roll, inspect the core and see if you can identify the material used to support the weight and shape of the material.
