Flat boxes ideal for posting products up to 50 mm thick
Flat Brown Postal Boxes provide a sturdy and reliable alternative to traditional mailing bags, offering enhanced protection for your flat items during transit. Designed with a height of 50mm, these boxes are perfect for posting or presenting books, DVDs, documents, and other slim items that require a robust packaging solution. The clever design makes these boxes easy to assemble without the need for glue or tape and they’re easy to open and re-use too.
Ideal for businesses and individuals alike, flat postal boxes are not only strong but also more cost-effective compared to regular, bulkier boxes. Their compact design reduces the need for excess packaging materials and makes for a more efficient process. The integrated lid and double reinforced sides offer extra protection, ensuring that your items remain secure throughout their journey. As they are resealable, then it’s advisable to tape the opening when sent through the post.

How to use the flat brown postal boxes:
- Take the flat-packed postal box and carefully unfold it. Begin by lifting the sides and folding along the pre-scored lines to form the box's basic shape.
- Fold in the side flaps first, followed by the larger flaps, to create the base of the box.
- Carefully place your flat items, such as books, DVDs, or documents, into the box. If your items need extra protection, consider wrapping them in bubble wrap or using paper packaging as padding at the bottom of the box. Ensure the items fit snugly to prevent movement during transit.
- Fold the top flaps of the box over the contents, starting with the smaller flaps and finishing with the larger flap that forms the lid. The integral lid should fit securely over the contents, and the sides will interlock to provide a secure closure
- For added security, seal the box with packaging tape along the edges.
- Attach any necessary packaging labels, addresses, or instructions on the top of the box. Your flat brown postal box is now ready for storage or shipping.
