In 2004, Spiral Paper Tube & Core started manufacturing Edge Protectors.
WHY ARE EDGE PROTECTORS NEEDED?
Paper prices were on the rise and manufacturing corrugated boxes became increasingly more expensive. In order to keep providing cardboard boxes at reasonable market prices, manufacturers decided to use lower quality paper.
The most common example of a low-quality paper product is the egg carton. The paper used to make an egg carton has been recycled so many times that it can only be molded or formed. It has very little structural strength, but it is good enough to hold a dozen eggs.
