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

The mailer is designed to fold neatly around the contents, holding the item securely during transit. Perforated strips allow the width to be 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 each end to protect against knocks and drops.

Cost Efficiency

Mailers up to size 2 can be used to send thinner items at the Royal Mail Large Letter rate, provided the total thickness does not exceed 25 mm. To support this, our mailers are available in multiple board thicknesses. For example, an E-flute mailer can safely send a DVD via the Large Letter service.
