These corrugated boxes refer to used containers or packaging made from unbleached, unwaxed paper with ruffled (‘corrugated’) inner lining-said corrugated materials (also known as containerboard) make up the likes of pizza or shipping boxes.
So far, a shortfall in the production of semi-conductor chips, an industry that helps generate a lot of OCC, has led to a shortage in available corrugated containers. Paper mills across the Midwestern US have offered to pay premiums on top of prices far higher than the national average to garner access to said corrugated boxes.
