Frequently Asked Questions (FAQs)

1. What is the difference between flat cardboard and corrugated cardboard?

Traditional cardboard is a thicker, heavier version of paper stock or pulp. For example, a cereal box is made from cardboard. Corrugated, on the other hand, might be made with cardboard materials, but the overall design and structure is much more durable.

2. What is flat cardboard called?

Linerboard is the flat, outer surface that adheres to the medium. The medium is the wavy, fluted paper between the liners. Both are made of a special kind of heavy paper called containerboard.

3. What is the difference between carton box and corrugated box?

Although corrugated cartons are made with some cardboard, it's important to know that these materials are not the same. Corrugated is made up of three layers of paper that includes an inside liner, an outside liner, and fluting with a ruffled shape, which runs in between the two.
