Blake Envelopes are the marketing leader in all envelopes across the UK and Europe which includes our White Envelope range. Our vast range of White Envelopes are available in a variety of sizes including the popular C4, C5 and DL, as well as a huge selection of other options. Our Envelopes also have a number of styles to choose from including standard, padded, cardboard and bubble padded envelopes to name a few. Our envelopes are packed in multiples of 1,000 or boxes of 250/500.

Consistency of product is paramount to us and stringent manufacturing criteria ensures this is maintained. All of our grades are made from specified papers, some of which have been specially developed for us to meet market needs. The internationally recognised Blake registered opaque is not only attractive in its appearance but serves to enhance the whiteness of any paper and provides maximum security to the envelope’s content.

If you can’t find what you are looking for, please give our friendly customer service team a call, we are always happy to help.
