7 Ply Corrugated Box

A 7-ply corrugated box is a cardboard box made of seven layers of paperboard material. The box consists of three layers of paperboard, two layers of corrugated medium, and two layers of liner board. The thickness of the paperboard used in a 7-ply corrugated box can range from 2.4mm to 8mm. The thicker the paperboard, the more weight it can support. However, the weight capacity also depends on the size of the box.
