Sealing Methods and Closure Devices

Seal Adhesive (Gum)

Activated by moistening when flaps are about to be sealed.

Simple-Seal^®

Self-adhering latex adhesive on two surfaces that seal on contact. The unique folded flap feature on stationery envelopes keeps the two latex flaps separate until sealing is desired.

Clasp

Double-pronged metal clasp for added security. Envelopes with this closure treatment cannot be run through graphic or other automatic processes after conversion.

Button & String

Tie-down closure for repeated use. Envelopes with this closure treatment cannot be run through graphic and other automated processes after conversion.

Latex Seal

Self-adhering latex adhesive on two surfaces that seal on contact without moisture. Flaps are extended and adhesive is exposed. Envelopes with this closure are not recommended for automatic insertion or laser applications.

Strip and Grip^®

A release tape liner is applied over a latex adhesive. When the liner is removed and the flap is pressed down, it seals on contact
without moisture. Printing after the envelope is folded can be accomplished without interfering with the quality of the seal.

Tac -n-Tac^™

A Tac -n- Tac seal tape closure allows reusable sealing of flap. Envelopes can be printed after folding
