The BSC PREFERRED EN1018 is a reinforced clasp envelope built for repeated use in mailrooms, offices, and shipping operations. Each envelope features a metal clasp closure that allows the envelope to be opened and resealed multiple times without damage. For a permanent seal, a gummed flap is included - moisten and press closed to secure contents. The envelope stock is a strong 28 lb woven construction, giving it durability for heavier documents, multi-page packets, and internal routing. This case contains 500 envelopes and is a standard supply order for facilities with consistent mailing volume.
These clasp envelopes are suited for internal document routing, interoffice mail, and outbound correspondence requiring a reusable closure. The dual-closure design - metal clasp plus gummed flap - gives the installer or mail handler the option to keep documents accessible through multiple handling cycles or seal them permanently for final delivery. Common users include administrative staff, records departments, shipping teams, and facilities management personnel managing high-volume document flow.
Designed as a standard clasp envelope for general office, mailroom, and interoffice document handling applications.
No tools required for use. To activate the gummed flap, moisten lightly and press firmly closed; allow adequate drying time before stacking or processing. When using only the metal clasp for reusable routing, avoid bending the clasp excessively to extend its service life. Store unused envelopes flat in a cool, dry location to prevent moisture activation of the gummed flap.
