6 x 9" Kraft Gummed Envelopes

These 6 x 9 inch Kraft gummed envelopes are built from 28 lb opaque paper stock that prevents contents from being visible through the envelope wall. The water-activated gum flap creates a firm, tamper-evident seal once moistened and pressed — no adhesive strips or separate sealing materials needed.

The internal format fits standard documents, invoices, folded correspondence, and promotional inserts without additional folding, making these envelopes a practical choice for corporate mail rooms, print shops, fulfillment centers, and interoffice distribution operations.

Each case contains 2,500 envelopes. The natural Kraft finish accepts inkjet and laser-printed address labels cleanly, supporting efficient address application at volume. Cases ship via parcel carrier.
