Envelope Sealing Guide

Peel & Seal

Press Seal

  • Press the two layers of adhesive (one on each flap) together to form an instantly strong bond. Seal strength weakens after a six month period. for peace of mind security slits are often added to clearly identify whether an envelope has been opened.

Gummed Seal

  • Moisten the layer of adhesive along the envelope flap and close.

Twin Gummed

  • Double the amount of adhesive for a stronger seal.

Window Position Options
