The BSC PREFERRED EN1093 is an inter-department envelope designed for internal mail routing in office and facility environments. Made from 28-pound kraft paper, each envelope features a string and button closure that allows repeated use without degrading the seal. Both sides are pre-printed with five columns - Date, Deliver To, Department, Sent By, and Department - providing space for up to 52 routing entries per envelope. Facilities managers, mailroom staff, and administrative personnel use these envelopes to keep internal documents organized and routed accurately across departments without single-use waste.
These envelopes are suited for standard office inter-department mail workflows in commercial, institutional, and industrial facilities. They are sold in case quantities of 100 units, making them practical for high-volume mailroom stocking. The kraft paper construction holds up through multiple routing cycles, and the pre-printed columns eliminate the need for handwritten labels or custom forms. Typical applications include routing invoices, work orders, HR documents, and correspondence between departments or buildings on a shared campus.
Designed as a standard inter-department routing envelope compatible with typical office mailroom workflows. Equivalent to part number S-10018.
No tools or trade installation required. Store cases flat in a dry environment to prevent moisture damage to the kraft paper. Ensure routing columns are filled out completely before each send to maintain accurate delivery tracking. Envelopes should be retired from circulation once all 52 routing entry spaces are filled.
