The BSC PREFERRED EN1024 is a case of 250 gummed-flap envelopes designed for secure, professional mailing. Each envelope is constructed from 28 lb. paper stock, providing durability and resistance to tearing during handling and transit. The paper is opaque, preventing contents from being visible through the envelope walls. The flaps carry a heavy gum coating that bonds firmly when moistened, eliminating the need for tape or additional sealing materials. These envelopes suit offices, warehouses, and distribution operations where consistent, reliable sealing is required in volume mailing workflows.
The EN1024 envelopes are suited for general correspondence, document mailing, and administrative use across commercial and light industrial settings. Sold in cases of 250 units, they are a practical stock item for mailrooms, shipping departments, and supply rooms that process regular outgoing mail. This product is equivalent to part number S-7797, making it a recognized replacement option for operations sourcing a known SKU.
Equivalent to part number S-7797. Suitable as a direct replacement for operations currently sourcing that part number in standard gummed-flap envelope applications.
No tools or trade licensing required for use. Moisten the gummed flap with water or a damp sponge before sealing to activate the adhesive. Avoid over-saturating the flap, as excess moisture may weaken the bond or cause wrinkling. Store cases in a cool, dry location away from humidity to maintain gum integrity until use.
