Seals and Closures

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

Remoistening Seal

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

Split Seal

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

Flip-Stik Seal

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
