C6 envelopes MAILmedia 212390 are silk-lined mailing envelopes with a paper weight of 80 g/m², supplied in a pack of 500.

With an 80 g/m² paper weight, these envelopes balance durability and flexibility for automated feeding and manual handling. The pack of 500 provides a cost-efficient supply for offices, mailing campaigns and event preparation while maintaining consistent quality across units.

How to use

Insert the folded document or card into the envelope so it sits flat against the silk-lined interior. Moisten the gummed flap evenly and press to seal. For mailing, ensure addresses and postage comply with postal service guidelines; for bulk mailings, test-feed a few envelopes in your mailing equipment to confirm compatibility with the 80 g/m² paper weight and gummed closure.

Usage recommendations

Store envelopes in a dry, cool environment away from direct sunlight and humidity to preserve the adhesive on the gummed flap and the integrity of the silk lining. For best presentation, allow glue to set fully before stacking; when using automated mailing systems, run a small batch test to verify machine settings.
