Gummed flaps need to be moistened or licked. Self seal envelopes are sealed by pressing one strip of adhesive against another (flap to flap or flap to envelope body). A strip of silicon protects the adhesive on a peel and stick flap, when it’s pulled off the envelopes is sealed by pressing the flap against the back of the envelope.
