Cardboard envelopes and mailers

Give your products extra protection in transit with sturdy cardboard envelopes and mailers

When documents are in the post, there’s always the chance they could get damaged or bent while they’re on the move. By adding cardboard mailers and envelopes to your businesses post-room, you can help ensure that products are kept safe while they’re travelling from A to B. Boasting a wide range of cardboard and card-backed packaging materials in a variety of sizes, you have a plethora of cost-effective options to pick from.

For products like certificates, contracts, and important documents, our card backed envelopes will help ensure they arrive safely. Pre-printed with ‘Please do not bend’, each of these hard envelopes make sure your deliveries are handled carefully while in the post. To make your postal packaging supplies even easier, our board backed envelopes also come in 6 popular sizes.

If you are looking for ways to send out larger documents like magazines, books or DVDs, then using cardboard mailers and envelopes is an excellent option to provide some extra protection. Designed to be flexible, there are plenty of options available to help you send out products are varying sizes. Plus, there are multiple closure types, including peel and seals strips, to save on sealing times.
