The BSC PREFERRED SLE12162WE is a case of 100 expandable Ship-Lite mailer envelopes designed for shipping books, catalogs, documents, and other bulky or flat items. Each envelope is constructed from white paper reinforced with a mesh screen of poly fibers, making it six times stronger than a standard paper envelope. The moisture-resistant construction protects contents from light handling exposure during transit. A self-seal closure eliminates the need for tape or additional fasteners, speeding up pack-out workflows in mailroom, warehouse, and shipping operations.
These envelopes are well-suited for commercial shipping rooms, fulfillment centers, and office mail departments that regularly send books, bound materials, or irregularly shaped flat goods. The expandable design accommodates items with added thickness without compromising the envelope structure. Sold as a case of 100 units, this SKU is practical for operations with moderate to high outbound shipping volume. The equivalent part number for cross-reference purposes is S-6370.
Equivalent to part number S-6370. Designed as a general-purpose expandable mailer envelope for commercial and office shipping applications.
No installation is required for this product. For best results, ensure contents are seated fully within the envelope before engaging the self-seal strip. Store cases flat in a dry environment to preserve the adhesive seal integrity. Handle sealed envelopes with care to avoid stress on the seam when envelopes are fully expanded.
