Long and flat postal boxes  ( 9 products )

Our unique range of flat and long boxes are strong enough to protect delicate or over-sized products in the post and don’t require tape or glue. Our durable flat boxes are ideal for items that are less than 50mm thick and resist knocks and scrapes in transit. For added convenience, our postal boxes are also easy to stack and easy to assemble. A self-seal pad or strip also makes them simple to fasten and eliminates the need for extra strapping or adhesives.

If you’re looking to post longer items, rolled products or components, choose our long postal boxes. For everyday posting, choose our single-use standard postal boxes that seal securely with a self-adhesive strip. Or premium postal boxes that can be easily opened and re-closed, and are suitable for long-term storage.
