Cardboard Envelopes

Cardboard Envelopes, or more commonly All-Board Mailers are a popular, more rigid alternative to traditional Envelopes.  Made from 350gsm board, Cardboard Mailers offer solid protection and bend resistance on both sides of the envelope.

All-Board Mailers are typically used for documents or valuable items which aren’t able to be flexed in transit, or for those looking to offer a more professional postal solution. Their convenience and flat-packed storage benefits mean Cardboard Envelopes, alongside Book Wrap Boxes, are widely used by Amazon and other large eCommerce operations. 

Our All-Board Mailers offer a print-free manilla exterior, meaning they are entirely customisable where required, as well as offering the time saving peel-and-seal closure.

Most sizes of our All Board Mailers also fit into either the Royal Mail standard ‘Letter’ or ‘Large Letter’ size, meaning not only will your items be protected, but your wallet will too! For those looking to send larger items such as posters, we have many sizes of Postal Tubes available as a fuss-free and economical alternative.
