Benefits of Self Seal Over Traditional Envelopes

Self sealing company envelopes offer practical advantages that traditional gummed-flap envelopes don’t:

• Faster processing. Peel-and-press closure speeds up mail preparation, especially for bulk mailings.
• Cleaner handling. No moisture means no warping, no curling, and no unpleasant taste.
• Reliable seal. The adhesive strip creates a strong, tamper-evident closure that stays shut through processing and delivery.
• Longer shelf life. Traditional gummed adhesive can dry out over time. Self seal strips maintain their bond strength for years in storage.
• Professional appearance. Clean, flat seals look sharper than envelopes closed with tape or uneven moisture application.
