Shipping Mailer Boxes

We make shipping mailer boxes that get your products to your customers intact. Each box keeps its shape under stacking pressure, stays closed through carrier handling, and fits the product it carries.

For small businesses, we build each mailer around the product you ship. It’s made to your dimensions in 18pt card stock, 24pt card stock, or corrugated board, depending on product weight. Each mailer has a self-locking closure, and we add protective inserts where the order needs them.

Shipping Mailer Boxes Made to Your Product’s Dimensions

We die-cut mailer boxes to your product’s length, width, and height.

A snug fit adds about 1/8 inch of clearance on each side, roughly 1/4 inch across each dimension. That limits movement and void fill while keeping the product from pressing against the walls during packing and transit. If you use an insert, include it in your measurements.

For products that fit standard dimensions, we also offer stock sizes, including 6 × 4 × 3 inches and 9 × 7 × 2.25 inches. But The Premier Packaging is known for making custom boxes for SMBs. So rest assured that we’ve got you covered if your product doesn’t fit premade box dimensions.

Card Stock or Corrugated Board, Matched to Product Weight

We make mailer boxes in 18pt card stock, 24pt card stock, and corrugated board in E-flute (1/16 inch) or B-flute (1/8 inch). Without specifying any sizes, we want to make it clear that we aren’t limited to offering premade box dimensions only.

For informational purposes, know that 18pt card stock suits smaller, lighter products, and 24pt adds rigidity for larger mailers. For heavier or bulkier products over 5 lb, we recommend E-flute or B-flute corrugated boards to withstand stacking, compression, and drops in transit.

We match the board to the product’s weight and dimensions rather than defaulting to the thickest option.

A Closure Built Into the Box

Our shipping mailer boxes come with a roll-end tuck-front construction: the box locks closed through its own folded structure, with no tape or glue required. Packing stays fast when you ship orders every day, and the locked structure keeps the package closed in transit.

Protective Inserts Where the Product Needs Them

When a product needs extra support, we add cardboard, corrugated, or foam inserts cut to fit the product. Inserts hold the product in position so it doesn’t shift in transit, and the box walls resist pressure from outside.

Size, Board, and Construction Chosen Together

We set box size, board, closure, and fit as one specification. A box that is too large leaves room for the product to shift. A box that is too small presses on the product. A board that is too thin may not protect the product in transit.

Full-Color Printing on the Box You Ship

Your mailer is the first packaging your customer handles.

We print in full color (CMYK), with Pantone (PMS) matching for exact brand colors, on the outside or on both the outside and inside. You can add your logo, contact details, handling marks such as “Fragile,” or other artwork directly to these shipping mailer boxes.

Our free design support includes a flat-view proof and a 3D mock-up, with physical samples available on request, so you can approve the box before production.
