Envelopes from Twofold Ltd

Looking for a wide range of envelopes to suit almost any purpose?

We offer a wide selection of machine compatible, bespoke and self-seal envelopes in a range of sizes, window sizes and positions. You can take advantage of our FREE storage for up to 12 months, allowing you to make savings on larger orders and schedule call off when you need them through the year. We deliver almost everywhere in the UK and in most cases can deliver next day if ordered before 1.30pm.


Sending confidential documents?

Twofold can supply you with envelopes that feature a unique “Checksecure” opaque, which is specifically designed for the protection of confidential or sensitive documents. Combined with the dark security opaque, the checksure text pattern prevents envelope scanning by powerful light sources such as halogen bulbs, and cannot be scanned using solvent applications such as “Scan Mail” spray. All that will be revealed is the security opaque, where a standard blue opaque will reveal the contents of the envelope.

Our range of consumables is designed to enhance our machines, ensuring maximum product performance and longevity.


Just some of our popular envelopes:

  • CheckSecure Protective Envelopes
    Need to send confidential items? CheckSecure Protective Envelopes are specifically designed for the safe sending of valuable and confidential items in the post, such as cheques.
