Mailer Boxes

Custom Mailer Boxes for Safe and Reliable Shipping

E‑commerce founders and solo sellers carry angst when shipping their products. The issue of shipping is a reasonable concern, but it can be solved using custom boxes.

The Premier Packaging makes self-locking mailer boxes for everyday shipping, made from high-grade cardboard and corrugated board. These materials for making mailing boxes stay strong while keeping shipping weight low.

So, if you are looking for a shipping box that can both promote and protect the products you sell, our customized boxes are the answer.

Standard Sizes and Optimized Dimensions

We offer a range of standard mailer box sizes for subscription boxes and e-commerce retailers, each dimensioned to align with major USPS and FedEx rate classes. Every box uses the roll-end tuck front style — a self-locking design that assembles quickly without tape or glue.

Beyond these standard sizes, we die-cut boxes to your exact dimensions for a snug fit, so you need less void fill.

Stock Thickness and Durability

When it comes to buying mailer boxes, the material or paperstock that you select is vital, as it shapes both the product it protects and the overall personality of your brand. So, we offer corrugated board that is valued for its strength, as well as premium card stock that is chosen for a more refined and extravagant finish, so you can pick the best custom box to ship your products

• 18pt card stock: This is a smooth paperboard that is well-suited for smaller, lighter goods, and it comes in sizes such as 5x3x1.5 in and 6x5x2.25 in. Moreover, it stays rigid for its weight while giving your boxes a clean, refined feel that buyers tend to appreciate.
• 24pt card stock: This is a thicker, sturdier board that is recommended for larger mailers such as 9x6x4 in, along with products that require extra rigidity. Hence, its heavier feel reads as premium, which is one of the reasons luxury retailers so often lean toward it without hesitation.

For heavier or bulkier items above 5 lbs, we suggest you choose from our e-flute or b-flute corrugated board options, as these are designed to keep your products secure and protected while they are in transit.

Custom Printing and Finishing

Custom printing and finishing turn a shipping box into a branding opportunity. Choose from our versatile state-of-the-art printing options.

• Print coverage: Choose how much of the box carries your branding:
  • Outside only: All branding prints on the exterior for maximum recognition on delivery.
  • Inside and out: Printing the interior walls adds thank-you notes, patterns, or brand stories, building a richer unboxing experience for the customer.
  • Plain (unprinted): A low-cost, minimalist option. Eco-conscious brands favor the natural kraft look, often paired with a branded sticker or label.
• Color systems: We print in CMYK for full-color artwork and match exact brand colors with the Pantone Matching System (PMS).
• Lamination finishes: Laminate coatings protect the printed ink and add durability and a distinct feel.
  • Matte lamination: A non-reflective, soft-touch surface that cuts glare for a modern, high-end look.
