Plain or Window C4 Envelopes:

Window C4 envelopes when folded properly, allow you to display the address printed on the letter. These look very professional which makes them a popular choice for businesses of all sizes. Plain C4 envelopes do not have a window and are widely used both in the home and the office.

C4 Envelopes Seal Types

• Peel & Seal C4 Envelopes – This is a very common way of sealing C4 envelopes. The flap of the envelope has a strip of glue which is protected with a strip of plastic. Remove the plastic strip from the flap and press against the envelope to seal.

• Press Seal C4 Envelopes – Press seal C4 envelopes are also very common and similar to peel & seal C4 envelopes, the difference being both the envelope and the flap have strips of adhesive. These are pressed together to form a strong bond.

• Gummed C4 Envelopes – This is the more traditional way of sealing an C4 envelope. Gummed envelopes have a strip of adhesive that becomes sticky when moistened. These C4 envelopes are often cheaper than peel & seal or press seal envelopes.

Here's what our customers are saying...

James Crowley   
Basildon Bond C4 White Window 100gsm Envelopes Pocket Peel and Seal Recycled Pack 50 Ref B80285
  Can't Fault These Envelopes!   
  "Having used cheap C4 window envelopes before and been disappointed with the quality I decided to go for a more well known brand. These Basildon Bond white envelopes are the finest quality I've used in a while as well as being very reasonably priced for a pack of 50. At 100gsm they're not the thickest I've used but still sufficient for what I need to use them for. The peel and seal makes life much easier as well as keeping my documents safe and secure inside. Cannot fault these or the service from huntoffice."
