Custom
Shipping Boxes

Seven stock sizes cover most of what ships in a carton, from a 6 × 6 × 6 inch cube for a single product to a 17 × 14 × 12 inch case for wholesale orders. Pick the one that fits closest and the quote card prices it on the spot. Need something in between, bigger or an odd shape? We make custom sizes to order. Choose Custom size in the quote card, tell us the inside dimensions and the quantity, and our team quotes it as soon as possible.

Sizes are inside dimensions, written length × width × depth. Length and width are the two sides of the base, depth is how tall the box stands when closed. The walls add about a quarter inch outside, a little more in depth where the flaps stack, and we hold a tolerance of 1/8 inch on shipping boxes because of the glued corner joint. Carriers size a parcel by its longest side plus the distance around the other two. Our largest stock box measures about 69 inches that way, comfortably inside the USPS, UPS and FedEx limits.

Both surfaces sit on the same single-wall B-flute corrugated board, 32 ECT and about 1/8 inch thick. Corrugated board is a fluted inner layer glued between two flat liners. B-flute is the medium wave, about 47 flutes per foot, thick enough to cushion a drop and smooth enough to carry sharp print. ECT is the edge crush test, the standard measure of how much stacking load the board takes. The two options differ in the liner, the paper you print on.

Choose White Board for colors that print bright and true, or Kraft Board for the natural, unbleached look that many brands pick on purpose. Hover over the photos to see the texture up close.

We print directly on the board, edge to edge and on every outside face, on digital presses with UV-cured inks. There are no labels and no laminated wraps, so the print is part of the box, and you can change the artwork between orders at no charge.

Digital printing on corrugated skips the plates a flexographic press needs, which is what lets photographs, gradients and small type print cleanly on B-flute. The ink lands on the liner and cures under UV light at once, dry and rub-resistant before the sheet is cut, scored and glued.

Bring your logo and your website's palette to the loading dock in full CMYK color, with clean lines and fine detail that stay consistent from the first carton in the run to the last.

A shipping box arrives glued and folded flat. Pop it open, fold the bottom flaps in, short flaps first, and run one strip of tape along the seam. Pack, add void fill if the product needs it, fold the top the same way and tape. For heavier loads an H pattern of tape across the end seams adds strength. A practiced packer does it in about fifteen seconds, which is why the style has been the standard for a century.

Every Packwire shipping box is made locally, in the United States, close to the customers it ships to and by people you can reach on the phone. Local manufacturing is what makes the rest possible, from shorter lead times and fewer supply-chain surprises to less freight on every order and the same quality from one run to the next. The board contains at least 50 percent recycled fiber and the finished box is curbside recyclable across the US.

A box that fits its contents needs less void fill and avoids the carrier charges that are based on size rather than weight, known as dimensional weight. Our DIM weight calculator shows how a size change moves that charge. Corrugated inserts and partitions, available from 500 units, recycle with the box.
