What the AI looks for in Envelope Seals
- Seal type
- Clear tab or wafer seals close folded self-mailers; decorative seals are for envelopes that are already closed. They solve different problems.
- Postal suitability
- Folded self-mailers generally need tabs to be machinable; follow your postal service's rules on tab size and placement. Mailers without proper tabs can jam sorting equipment or incur surcharges.
- Adhesive strength
- Use permanent adhesive for mailing. Removable seals can pop open in transit.
Brands that matter
- Avery: Clear round labels used as wafer seals.
What to avoid
- Removable-adhesive seals on mail.
