The BSC PREFERRED EN1016 is a kraft clasp envelope designed for repeated use in office, shipping, and document-storage applications. Each envelope features reinforced metal clasps that allow the flap to be opened and reclosed multiple times without loss of function. For a permanent seal, a gummed flap is also included - moisten and press to close. The envelope body is constructed from strong 28 lb. woven stock, providing durability for inter-office routing, filing, and mailing of multi-page documents. Sold as a case of 1000 units, this SKU suits high-volume operations that require a reliable, reusable envelope solution.
These envelopes are well suited for office supply rooms, mailrooms, document-management workflows, and shipping departments. The dual-closure design - metal clasp plus gummed flap - makes them practical for routing packets that are opened and resealed across multiple recipients or departments. The 28 lb. woven construction resists tearing during handling. This product is noted as equivalent to part number S-12916, making it a direct substitute in existing procurement systems.
Equivalent to part number S-12916. Designed as a standard-format kraft clasp envelope suitable for general office, mailroom, and document-routing applications.
No tools or trade licensing required for use. Store cases flat in a dry environment to prevent moisture from activating the gummed flap prematurely. When sealing permanently, moisten the gummed flap evenly and press firmly for full adhesion. Do not overfill envelopes beyond the rated capacity, as this may stress the clasp or seams.
