These 9 x 12 inch white gummed envelopes are built from 28 lb opaque paper stock, preventing contents from showing through the envelope wall. The heavily gummed flap activates with moisture to form a firm, reliable seal — making these envelopes a dependable choice for high-volume mailing and recurring document dispatch.
The interior opening fits standard letter-size documents, catalogs, and flat inserts without folding. The clean white exterior accepts printed labels, postage meter imprints, and stamps cleanly, suiting office mail rooms, fulfillment centers, and administrative departments managing regular outbound correspondence.
Constructed from 28 lb paper with an opaque finish, these envelopes balance sheet strength with mailability. Each case contains 1,000 envelopes, supporting bulk mailing programs and consistent replenishment cycles. Cases ship via parcel carrier.
