What are Paper Cores
Paper cores are long cardboard tubes with strong resistance to pressure from the outside. They go by the names spiral-wound paper cores and cores made of fiberboard. Adhesives are used for laminating or gluing the paper layers together.
During production, the number of layers wrapped might affect the tube's wall thickness. A paper core is essentially a paper tube with a thick wall. Paper cores' substantially thicker walls allow for the winding of flexible webs or sheets into rolls during conversion processes.
Material Used to Make Paper Cores
Paper or paperboard wound plies are used to make paper cores and related goods. Brown kraft paper or paperboard can be layered in one, two, or more plies to create paper cores.
The liner, which is the innermost layer or plies, and the wrap, which is the outermost layer, can be made of special paper or various other materials (foil, film, etc.).
The specialist paper and materials might offer color, images, or labeling in addition to water resistance.
To summarize, paper cores are made from wood pulp in the form of recycled paper, paperboard, paper-adhesive composites, cardboard, kraft paper, waterproof/water-resistant cardboard, and fiberboard.
