The BSC PREFERRED EN1009 is a heavy-duty clasp envelope designed for repeated use in high-volume mailing and filing applications. Each envelope features reinforced metal clasps that allow the flap to be opened and resealed multiple times without damaging the envelope body. A gummed flap provides a secure, permanent seal when moistened and pressed closed. Constructed from strong 28 lb woven stock, these envelopes hold up to frequent handling in mailrooms, offices, and distribution centers. Each case contains 500 envelopes. The case ships at approximately 36.42 pounds with package dimensions of 18.25 inches x 19 inches x 12.75 inches.
These envelopes are suited for office environments, mailrooms, facilities management operations, and businesses that process large volumes of interoffice or outbound correspondence. The dual-closure design makes them practical for documents that need to be routed between departments and reused, reducing overall envelope consumption. They are sold by the case in quantities of 500 units per case.
Designed as a direct equivalent to part number S-5877. Suitable for standard office, mailroom, and interoffice correspondence applications requiring a reusable clasp envelope.
No tools or trade licensing required for use. Store envelopes flat in a cool, dry location to prevent warping or premature adhesive activation on the gummed flap. When sealing permanently, moisten the gummed flap evenly and press firmly for several seconds to ensure a complete bond. Do not expose stored envelopes to high humidity, which can cause the gummed flap to adhere prematurely.
