Corrugated Boxes

Corrugated fiberboard has two main components: linerboard and the medium. Linerboard is the flat surface of the box and fluting is the wavy medium attached to the linerboard. There are four types of corrugated structure:

• Single Face: One flute and one linerboard
• Single Wall: One flute between two linerboards
• Double Wall: Two flutes within three linerboards
• Triple Wall: Three flutes within four linerboards
