Corrugated fiberboard is a paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards.
Corrugated fiberboard paper comes in two forms, lined and unlined. For art and craft purposes, lined corrugated paper is usually used. Lined corrugated paper is rigid layered paper that encloses a fluted layer between one or two smooth “liner” layers. The fluted layer provides added strength. Paper we know as cardboard is actually lined corrugated paper. Unlined corrugated paper consists of the fluted layer only and is flexible.
Corrugated paper products are lightweight, versatile and durable.
