Most people refer to any paper-based box as cardboard. But in reality, cardboard and corrugated packaging differ significantly, and using the wrong type can lead to costly consequences.
Cardboard (or paperboard), works just fine for a cereal box on a grocery shelf. But if this same material were used to ship glassware across the country, it would likely result in product damage and increased returns. Corrugated packaging, on the other hand, is specifically engineered to handle the stresses of shipping, including storage and handling.
