What is corrugated?

Made economically from a renewable, recyclable resource, Corrugated Board is comprised of two main components – Linerboard and Medium. Linerboard is the flat piece that make up both sides of the corrugated. Medium is the wavy, fluted paper in between the liners. The wavy flutes create arches when horizontal and columns when vertical. The arches and columns then provide cushioning and stacking strength to the finished product. The two primary types of Corrugated Board that we use are Singlewall and Doublewall. Both options are available in Natural Kraft (brown) or White.

Most items at your favorite supermarket or shopping mall were safely delivered in boxes made of corrugated cardboard and many are displayed in the same boxes, which were manufactured so they could be opened and used for this purpose. Because corrugated cardboard is such a versatile packaging material, millions of tons are used each year to protect and display products. More than 80 billion corrugated boxes are used in the United States each year and it is the most recycled product on the planet.

How to Measure a Box

Box makers prefer to measure and express box dimensions based on the inside of the box. Accurate inside measurements are crucial to ensure the right fit.

The measurements are shown as Length x Width x Height. Length is the longer side of the opening. Width is the shorter side of the opening. Height goes up from the bottom of the opening, and it's also the height of the box.
