Help & FAQs

Postal boxes are cardboard boxes used for shipping goods through the post or by courier. Returnable boxes often feature two self-seal strips so they can be used for product returns.


Made from corrugated cardboard, postal boxes can be used for shipping a wide range of goods. Many postal boxes come in Royal Mail or An Post sizes, sometimes called PIP boxes. This means they’ll be suitable for use through these postal service providers.



You can buy a wide range of postal boxes from Macfarlane Packaging. Our range includes:


  • Standard Postal Boxes
  • Returnable Postal Boxes
  • Unlined Postal Boxes
  • Postal Boxes with Foam Inserts
  • Postal Wraps & Book Wraps
  • Cardboard Envelopes
  • Postal Tubes
  • eCommerce Boxes
  • Magnetic Gift Boxes
  • Bottle Boxes
  • Korrvu® Suspension and Retention Packs


Postal boxes, including our standard postal boxes, come in many different sizes. When selecting the size of postal boxes you need, you should consider the courier partner you’re using, as well as the size of the goods you’re shipping.


For example, if you’re using Royal Mail, you might want to consider their standard sizing as a guide. PIP boxes or parcel boxes are recommended to be no bigger than the following sizes:


  • Letter: 240mm (L) x 165mm (W) x 5mm (D)
  • Large Letter: 353mm (L) x 250mm (W) x 25mm (D)
  • Small Parcel: 450mm (L) x 350mm (W) x 160mm (D)
  • Medium Parcel: 610mm (L) x 460mm (W) or 460mm (D)
  • Large Parcel: > 610mm (L) or > 460mm (W) or > 460mm (D)


Yes, our range of returnable postal boxes can be recycled. They’re also made from a high level of recycled content too, so they’re a good sustainable packaging choice for retailers, eCommerce and 3PL businesses.
