Extra flat boxes ideal for posting products up to 20 mm thick
RAJA's extra flat brown postal boxes are designed to perfectly fit Royal Mail post boxes and standard household letterboxes, making them an ideal way to send products up to 20 mm thick. These large letter postal boxes are crafted from durable micro-flute board, providing a sturdy and protective alternative to mailing bags without losing the easy post functionality. Available in a wide range of sizes, these boxes are perfect for shipping small, flat items such as documents, brochures, or slim electronics.
One of the key advantages of using large letter postal boxes over mailing bags or standard postal boxes is their ability to economise on postal costs. The slim, flat design ensures that your items are securely packed while minimising the overall volume, helping to keep postage fees low. When it comes to shipping lightweight, flat items, these boxes are often a more cost-effective and reliable choice compared to traditional packaging options.
For those requiring even more robust protection or a different shape, RAJA offers some specific long flat postal box alternatives, providing a solution for every need. Whether you need large letter postal boxes in bulk or are simply looking for the most efficient way to ship your flat products, these extra flat cardboard postal boxes offer the perfect balance of durability and cost savings.
How to use large letter postal boxes:
- Lay the box flat on a clean surface. Identify the pre-creased lines that guide the folding process. Begin folding the sides of the box upwards, following the creases to form the base and walls of the box.
- Once the sides are folded up, bring the flaps together to form the base of the box. Secure the base by folding the locking tabs into place, ensuring the box holds its shape. The tabs should easily slide into the slots designed to keep the base secure.
- Place your flat product, such as a brochure, document, or slim electronic device, into the assembled box. Ensure the item fits snugly inside without too much movement.
- Fold the top flaps down over your item and close the postal box by tucking in the top flaps.
- Write or attach your shipping label on the smooth surface of the box.
