Brown cardboard postal boxes

With the rise in ecommerce business and with companies looking for a more presentable solution than mailing bags or standard cardboard boxes, Kite’s brown postal box is the ideal solution. This simple yet effective design is very popular and would also benefit from our custom printed logo tape, great for ensuring goods are secure and for brand recognition.

Perfect when needing to send a variety of items in a professional box, our brown postal boxes are made from high quality single wall cardboard material. Available in four styles: tuck-in-flaps, fold-in-flaps, ecommerce and peel-&-seal, see images and more info for style specification. All of our tuck-in-flaps brown postal boxes have branding on the inside flaps, not visible when constructed. They can be used in conjunction with bubble wrap and void fill to secure products inside, or use coloured tissue paper for a more presentable solution. Our peel-&-seal postal boxes feature a secure sticky seal as well as a tear open strip.

Our ecommerce style boxes have a crash lock base design, they are simple to erect and with an integrated lid and peel-&-seal strip for secure closure, they are suitable for fast-paced environments, assembling in just seconds. Once goods are placed in the box, simply push the opposite corners of the box towards each other, making the base flaps automatically lock together and then seal with the integrated peel-&-seal strip. The box also has an easy to open tear strip, ensuring end-user satisfaction. Please note, branding may be visible on our ecommerce style boxes.

Lightweight but sturdy, these boxes are great for keeping costs down. All styles of box have a huge range of uses and have proven an extremely popular choice for e-commerce, mailing and fulfillment companies. All sizes in this range are delivered flat-packed, minimising the amount of space required to store them and making them easier to handle.

These one-piece cartons are quickly and easily assembled. For a more presentable solution, see our range of white postal boxes.
