A collection of our postal boxes which are suitable for A4 size items


This collection of A4 postal boxes offers an ideal solution for mailing A4 size items securely. With a focus on protection and practicality, these boxes serve to safeguard important documents, gifts, and various products. Unlike flat postal boxes which are perfect for flat items such as printed documents and letters, these boxes have a higher profile which makes them perfect for smaller products like delicate jewellery or branded merchandise.

Constructed from high-quality rigid flute corrugated board, these A4 postal boxes ensure the utmost security with their triple thickness sides, making them incredibly durable. Available in a professional brown or white Kraft finish, these boxes not only serve a functional purpose but also enhance the overall presentation of your shipments. Additionally, the flat pack design ensures efficient storage and transport until needed, facilitating easy handling.

Ideal for all A4 sized paper, documents (297 x 210 mm), or smaller items, these A4 postal boxes allow you to maximise space by using loose fill chips or bubble wrap to fill any gaps. Sold in convenient packs of 50 and priced per unit, they not only meet your shipping needs effectively but are also made from recycled fibres, and can be recycled again.

How to Use

  • Quickly assemble A4 postal boxes using the easy locking flap closure for secure delivery.
  • Utilise packaging tape to further enhance the security of the boxes, ensuring contents remain intact during shipping.
  • If necessary, protect the goods inside with void and loose fill.
  • Affix packaging labels so it's clear where the box is intended to be going.
  • Store boxes in a cool, dry space to prevent any damage before use, taking care to keep them flat and intact.
  • Consider additional box sizes such as A5 postal boxes for smaller items or A3 postal boxes for bulkier ones to cater to diverse shipping requirements.

Ideal Applications

  • Shipping A4 documents, such as contracts, reports, and correspondence.
  • Delivering small yet valuable items like jewellery securely without risk of damage.
  • Utilising as a storage solution for business essentials or personal records.
  • Compatible with packaging tape and labels for a complete mailing solution.
