C3 Envelopes Seal Types

• Peel & Seal – This is a very common way of sealing C3 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 sea.
• Press Seal – Press seal envelopes are also very common and similar to peel & seal envelopes, the difference being both the envelope and the flap have strips of adhesive. These are pressed together to form a strong bond. 

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

  Best out of all the C3 Envelopes   
  "When I was going through the sample envelopes I ordered for a bunch of certificates we are giving out at the college next month, I tried a 5 star, q connect, viking and new guardian type envelope. Without a shadow of a doubt this envelope was of far better quality."
