Our range of large letter postal boxes are perfectly sized for those wanting to keep postal costs to a minimum whilst sending smaller goods through the courier network. Designed to meet the Royal Mail large letter sizing, ensuring you don’t spend more than necessary on shipping costs. Manufactured using sturdy corrugated cardboard, our large letter postal boxes range is available as standard Fefco 0427 box design and supplied flat packed for space saving storage. The easy fold to assemble structure and integrated locking tab can be taped shut for extra security in transit. Stocked in both white and brown, these large letter postal boxes are available in a range of sizes and offer a great postal packaging solution for any eCommerce business. All of our large letter postal boxes are plastic-free, biodegradable, and made using recycled, sustainable materials.
Please note: Large Letter sizing is up to 353 x 250 x 25mm with a 750g weight limit.
Are large letter postal boxes recyclable?On their own, all of our large letter postal boxes in this range are fully recyclable. If you’re wanting to seal your postal box for additional security and safety, make sure you use paper tape instead of plastic packing tape. This way, your customers can easily dispose of your packaging by simply placing the whole large letter postal box into their home paper and cardboard recycling, without the need for removing the tape.
We all want to do our bit for the environment, but with so many packaging materials out there it can be tricky to know what can be recycled and how to correctly dispose of your packaging waste. Why not check out our recycling locator to find out what and where to recycle.
