About Our Mailers

We have been manufacturing these mailers for over 10 years, offering a wide range of sizes to suit different applications. They 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. All mailers feature perforated fold lines, allowing the width to be adjusted for a snug fit.

Protection

Once folded, the mailer provides three layers of cardboard to both the front and back of the item, along with a built-in crush zone at each end, helping to protect against drops and impacts.
