The BSC PREFERRED SLE10132WS is a case of 100 Ship-Lite expandable envelopes designed for heavy-duty mailing and shipping applications. Constructed from white paper reinforced with mesh screen poly fibers, these envelopes are rated six times stronger than standard paper envelopes. A self-seal closure eliminates the need for tape or moisture activation, speeding up pack-out workflows. The expandable gusset design accommodates bulky items such as books, catalogs, and multi-part shipments. Moisture resistance adds a layer of protection for contents in transit.
These envelopes are suited for mailroom, warehouse, and distribution center environments where durability and throughput matter. The expandable body makes them a practical choice when shipping items that exceed the flat profile of a standard envelope. The self-seal strip supports consistent, secure closure without additional sealing equipment. Sold as a case of 100 units, the SLE10132WS is appropriate for operations that require a reliable bulk envelope supply for recurring outbound shipments.
Designed as a general-purpose expandable mailer for standard outbound shipping and mailing operations in commercial, warehouse, and office environments.
No tools are required for use. Peel the self-seal strip liner and press the flap firmly to close. Store cases flat in a dry environment to maintain seal integrity and prevent moisture damage to the adhesive strip prior to use.
