Postal Cost Savings

• 3 mm board: Suitable when item thickness is under 8 mm

• 1.5 mm board: Suitable when item thickness is under 15 mm

• 4 mm double-wall board: Suitable when item thickness is under 5 mm

This allows thinner items to be sent securely while reducing postage costs.

About Our Mailers

We have been manufacturing cardboard mailers for over 10 years and offer a wide range of sizes. All mailers are produced using recycled cardboard and are fully recyclable after use.

Design

Each mailer is designed to fold neatly around the contents, holding items securely during transit. Perforated strips allow the width to be easily adjusted for a close, tailored fit.

Protection

When folded, the mailer provides three layers of cardboard on both the front and back of the item, along with integrated crush zones at either end to protect against knocks and drops.
