Description

Supply Air 18x14x12 Corrugated Cardboard Shipping Boxes are constructed from single-wall corrugated cardboard with a 32 ECT rating. Each box measures 18 inches in length, 14 inches in width, and 12 inches in height when assembled. The multi-depth design features pre-scored interior panels that allow adjustment to three different heights: 12 inches, 10 inches, or 8 inches. The boxes ship flat (knocked down) and assemble by folding along scored lines and sealing with tape. Brown kraft exterior finish. Regular Slotted Container (RSC) construction with top and bottom flaps that meet at the center when closed. Each box weighs approximately 1.8 pounds. Available in multiple pack quantities to accommodate varying volume needs. Manufactured in the United States. The 18x14x12 inch interior dimension accommodates items measuring up to 17.5 inches long, 13.5 inches wide, and 11.5 inches tall (when used at full 12-inch height). The multi-depth feature eliminates the need to stock multiple box sizes by allowing one box to serve three different height configurations. Assembly process: unfold the flat blank, fold the four side panels upward along the scored base creases, fold and interlock the bottom flaps in alternating pattern, seal the bottom seam with packaging tape, insert contents, fold top flaps closed, and seal the top seam with tape. The corrugated cardboard consists of an outer kraft liner, a fluted medium layer, and an inner kraft liner bonded together.
