Self-adhesive sealing with strip (HK) - the envelope is closed by removing the strip that covers the adhesive, placing the flap, and pressing the flap of the envelope. Fast, reliable, clean, practical, and convenient.

The strip has advantages over wet glue or self-adhesive closures:

• Envelopes are stored better because the seal is protected by a strip.
• They last longer and do not stick to the envelopes below.
• They are easier to fill and maintain their validity for over 5 years.
• They can be printed without issues, as the cover strip is on the opening flap, preventing adhesion in the printing device.
