The BSC PREFERRED EN1031 is a bulk-pack catalog envelope designed for high-volume mailing and document distribution operations. Each envelope is manufactured from 28 lb. paper stock, providing the structural integrity needed to protect enclosed documents during handling and transit. The paper is fully opaque, preventing contents from being viewed through the envelope wall. Flaps are heavily gummed to deliver a secure seal without requiring additional adhesive. This SKU ships as a case of 5000 units, making it well suited for fulfillment centers, print shops, and office supply rooms that process large outgoing mail volumes on a regular basis.
These envelopes are appropriate for general business correspondence, document mailing, and bulk direct-mail campaigns in commercial and institutional environments. The combination of heavy gum adhesive and opaque 28 lb. stock makes them a reliable choice for applications where content privacy and seal integrity are both required. Staff handling outbound mail, shipping clerks, and procurement teams managing consumable supplies are the primary users of this product.
Equivalent to part number S-5623. Suitable as a direct replacement or cross-reference for operations currently sourcing that part number.
No installation is required for this product. Store cases in a dry, climate-controlled environment to prevent the gummed flap adhesive from activating prematurely or degrading. Avoid stacking excessive weight on cases to preserve envelope flatness and prevent distortion of the paper stock.
