Paper Cores

Industrial paper cores for textiles and film

Erdie Industries makes paper tubes for use as spacers, covers and protectors with a wide range of dimensions.

All of our products, including those listed below, can have your choice of color or printed wrap and/or liner, with a variety of secondary operations.

Paper cores or cardboard cores are similar to paper tubes except for the way they’re used. They come in a variety of wall thicknesses and sizes for industrial use, such as tape cores, or for wrapping other materials, including paper, plastic, film, rubber, etc.

Our full-color high-speed printer allows for virtually endless printing possibilities depending on customer needs. Plies can be printed for either liners or outer wrap on any color paper.

We have machinery for customized notching, slitting, and punching for most sizes and wall thicknesses. We work with our customers to create custom processes and to reduce costs through the optimization of the production line.

We can ship our products either in cartons (via delivery service or freight), stretch-wrapped on pallets, tied in bundles, stacked on racks (provided by the customer), or stacked directly in tractor trailers. Please contact us if you have special shipping

Core Questions

What Exactly Are Paper Cores?

Paper cores are lengthy cardboard tubes fortified with exceptional resistance to external pressures. They are alternatively known as spiral-wound paper cores and fiberboard cores. These cores are meticulously assembled by laminating or bonding paper layers together using adhesives. The thickness of the tube's walls may vary during production, contingent on the number of layers employed. At its core (pun intended), a paper core essentially constitutes a paper tube distinguished by its substantial wall thickness. These stout walls of paper cores facilitate the coiling of flexible materials into rolls during conversion processes.

What Materials Are used to Form Paper Cores?

Paper cores and their related products are crafted from plies of paper or paperboard. Brown kraft paper or paperboard can be layered in one, two, or more plies to forge the foundation of paper cores. The innermost layer or plies, known as the liner, and the outermost layer, referred to as the wrap, can be fabricated from specialized paper or a myriad of other materials such as foil and film. These specialized materials may not only confer color, images, or labeling options but also impart water resistance. In summary, paper cores derive their essence from wood pulp in various forms including recycled paper, paperboard, paper-adhesive composites, cardboard, kraft paper, waterproof or water-resistant cardboard, and fiberboard.

What are the primary Varieties of Paper Cores?

Paper cores fall into two broad categories: spiral wound and convoluted (or parallel wound) cores. Convoluted wound tubes are preferred when applications require exceptional bend strength, crush resistance, and dynamic resilience. In spiral wound paper cores, paper plies spiral around the tube's axis, while parallel or convoluted paper cores feature paper strips wrapped in convoluted tubes parallel to or at a 90-degree angle to the tube's axis.

What are the different Applications of Paper Cores?

Paper cores find diverse applications across various industries, making them indispensable for a multitude of purposes. In the film industry, they serve as the backbone for film cores, particularly in polyester film and flexible packaging.

Self-adhesive tapes and adhesive labels also rely on paper cores, providing a base to protect the rolls from compressing or distorting durring shipment.

In the realm of textiles, paper cores play a pivotal role after the wool manufacturing process. Wool and other natural fiber materials are wound around these paper cores, which serve as the foundation for the entire transportation procedure. These cores are crucial for storing and transporting materials like denim, coir mats, and carpet yarn, safeguarding these valuable textiles during transit.

Paper cores serve as protective vessels for small engineering components and delicate items during packaging and shipment. Their ability to safeguard items from harm ensures the preservation of accuracy and balance, making them an ideal transport medium for precision commodities. For instance, items like spirit levels, prone to damage when transported in metal or other containers, are crafted with paper cores to facilitate secure and damage-free transportation.
