Sure Seal is a mail machine liquid for sealing envelopes.  Sure Seal ensures that envelope flaps stick down fast and stay sealed.  It works faster than water to activate the glue on envelopes and gum tapes.  Drying time is decreased allowing meter tapes to stick fast and stay put.  Once applied, your envelopes are ready to move.  Keeps wetting systems clean, free of algae, mineral deposits, and bacteria.  Works with all mail machines, inserters, and tape machines.  Ready to use.  No mixing required.  Simply add to mail machine water container.
