Edge Protectors are also known as Corner Protectors. They’re used to protect edges and provide additional column strength when used vertically. In the picture above, they’re being used to do both.
Edge Protector Facts:
- made with recycled paper
- usually white on the outside (top) and kraft brown on the inside (bottom)
- shaped into a 90 degree angle
- can be printed
Why Are Edge Protectors Important?
When paper is initially made from wood, it has long, strong fibers. Each time paper is recycled, the fibers are shortened, reducing its strength. A common egg carton is the end of the road. The paper has been recycled so many times it has no structural strength. It’s barely strong enough to hold a dozen eggs.
It’s more economical for corrugated box makers to use recycled paper to make boxes. The higher the recycled content, the shorter the fibers, the weaker the box.
The majority of business-to-business shipments (boxes) are sent on wooden pallets, which is why Edge Protectors are needed. Low-quality boxes are set on pallets, with an edge protector placed on each of the four corners, then stretch wrapped. Together, the wooden pallet, weak corrugated boxes, and thick Edge Protectors create a sturdy shipment.
It’s more economical for businesses to combine a cheaper, low-quality box with Edge Protectors than it is to purchase corrugated boxes made with less recycled content.
