Gummed (Glued) Seal Envelope:

  • The gummed flap envelopes are the most widely used kind of envelope seal. Furthermore, they are the least expensive too.
  • The word “gummed” means that the flap of the envelope has a strip of glue inside of the flap that must be wet so that the envelope can be sealed.
  • When you are dealing with mailing machines, only glued flap envelopes are permitted. There is a device inside of the machine that wets the glue.
  • Glued seals are the best way to seal an envelope because they are a bonded type of seal. Once wet and closed, the glue material develops a lasting bond.

Self-Seal Envelope:

  • Self-seal envelopes are a convenient alternative to the usually glued seal as they do not need licking or wetting to close.
  • Self-seal envelopes have a strip of adhesive on the flap, which has a removable strip of tape covering it. The tape can be peeled away so that the adhesive on the flap can be used to close the envelope.

Flip & Seal Envelope:

  • Flip & seal envelopes are fast to use and they don’t need licking or wetting to seal shut.
  • These envelopes have two strips of adhesive: along the flap and along the top back edge of the envelope. The top back edge is folded down to cover the adhesive.
  • To seal this type of envelope, just put your mail inside, and seal shut. The two adhesive strips are then sealed together.
  • Moreover, flip & seal envelopes have openings on atop the envelope, so it is easy and fast for people to tear open their mail.
