We offer and stock a wide variety of envelope seals and closures, including:

A gum seal activated by moistening the flap for a permanent seal

A gum seal split into sections and activated by moistening the flap for a permanent seal; better for storing envelopes in humid conditions.

Latex adhesive applied on two flap surfaces and folded to keep them separated until sealing; no moisture required

Self-adhering latex adhesive applied to two surfaces that seals on contact when joined.

Release tape liner applied over a resin adhesive. Remove liner and press flap down to seal; no moisture required.

Seal tape closure for reusable sealing; can be printed after conversion.

Reinforced, double-pronged metal clasp for added security. Should not be run through automated processes after conversion

Tie-down closures ready for repeat opening or secured sealing
