Corrugated liner

Corrugated Liner

Corrugated liner board, is a much stronger board that has two main components: the liner and the medium. The liner is the flat material typically found on the outside surfaces of the board (but can also be found on the inside of some heavier board combinations), and the medium, which can be found between the liners. The medium creates the arched shape or “flutes” between the liners and is a large contributor in the strength of the board. Once these sheets of paper are glued together they create a corrugated board which is then converted into a structure that can sustain long shipping journeys, bumps, and falls.

Corrugated liners are the outermost layers of corrugated cardboard, sandwiching the fluted medium between them. They are typically made from paperboard and are crucial in providing strength and rigidity to the overall structure. Corrugated liners come in various types and grades, each suitable for different packaging needs based on factors such as weight, fragility, and environmental conditions.
