White Postal Boxes

White Postal Boxes are designed to create slimline despatch solutions which minimise your postal costs. Made from robust corrugated for a sturdy mailing solution, these white postal boxes are of a standard 0427 design; supplied flat packed, folded to assemble and can be taped shut for enhanced security during transit. Perfect for despatch operations running on a budget, our low-cost postal boxes are all sized to fit within Royal Mail size constraints for Large Letter Postal Boxes and Small Parcel Postal Boxes. Available in a large range of sizes, we’re confident we’ll have a cardboard postal box which is perfect for your needs. As with all of our cardboard boxes, these postal boxes are recyclable, biodegradable, reusable, and made from sustainable and recycled materials.
