Description

Supply Air 6x6x6 Corrugated Shipping Boxes are constructed from corrugated cardboard with a 32 ECT (Edge Crush Test) rating. Each box measures 6 inches in length, 6 inches in width, and 6 inches in height when assembled. The boxes are manufactured from brown kraft paper with a single-wall corrugated structure consisting of one fluted medium layer between two linerboard facings. The material provides a crush resistance of 32 pounds per linear inch when tested perpendicular to the flutes. Each box is delivered flat (knocked down) and assembles by folding along scored lines and securing flaps. The bottom closes with four interlocking flaps that fold inward to form a base. The top closes with four overlapping flaps. No tape or adhesive is required for assembly, though external sealing tape is recommended for the closure flaps during shipping. The boxes accommodate items measuring up to approximately 5.75 x 5.75 x 5.75 inches allowing for internal packing material. This listing covers multiple pack quantity options ranging from 25 to 400 boxes per order. Each individual box weighs approximately 0.18 pounds. The boxes are manufactured in the United States and ship flat in bundled stacks.
