Description

Supply Air 8x4x3 Corrugated Shipping Boxes are constructed from single-wall corrugated cardboard with a 32 ECT (Edge Crush Test) rating. Each box measures 8 inches in length, 4 inches in width, and 3 inches in height when assembled. The brown kraft exterior provides a standard shipping appearance. These boxes ship flat and fold into a rectangular shape using interlocking flaps. The material consists of an outer kraft liner, a corrugated medium, and an inner kraft liner. Each corrugated box weighs approximately 0.18 pounds. The flaps interlock to close the box, and sealing tape is applied across the seams to secure the closure. These boxes accommodate items measuring up to 7.75 x 3.75 x 2.75 inches interior space. The 32 ECT rating indicates the corrugated board resists 32 pounds per linear inch of edge compression before deformation. The boxes are manufactured in the United States. Available pack quantities include 25, 50, 100, and 200 boxes per pack. The flat-packed boxes stack for storage and ship in compressed bundles. Each box consists of die-cut corrugated board with pre-scored fold lines.
