While the term “paper cores” often confuses people, these are actually common items that surround you in daily life. They are incredibly versatile and used for a variety of purposes, from manufacturing to household items.
What Exactly Are Paper Cores?
Paper cores are simply hollow, cardboard tubes that other materials are wrapped around. They are typically made from wood pulp fiber and adhesive and designed with enough durability to withstand their intended use. This means that the heavier the material that will be wrapped around it, the more layers the paper core will have.
Quick Facts About Paper Cores
- They’re most often made from recyclable paper. However, when necessary, other materials like hard plastic can be used.
- There are two basic designs. Spiral-wound and convolute, which is wrapped in a parallel fashion. Convolute is typically more durable than spiral-wound.
- Paper cores come in many shapes and sizes, depending on the item they are used for.
Common Uses of Paper Cores
There are a variety of uses for paper cores, but the following are the most common.
Paper cores are seen in homes every day. They are the rolls at the center of common items, like toilet paper, paper towels, aluminum foil, and cling wrap.

Peanut containers are used to store small items, like change and safety pins. Parents use a variety of these cores to store their kids’ toys. The possibilities are limitless.
