Bsc Preferred B911 Poly Mailers Self-seal 250 Per Case

Product Description

The BSC PREFERRED B911 is a polyethylene poly mailer sold in cases of 250 units, designed to protect shipments from moisture, punctures, tearing, and tampering in transit. The outer surface is white for easy labeling, while the inner lining is silver. High-strength seams hold contents securely even when the mailer is packed beyond its nominal capacity. A self-seal closure eliminates the need for additional tape or heat-sealing equipment. Labels, stamps, and standard ink adhere reliably to the white exterior surface. This product is an equivalent replacement for part number S-21874.

The B911 is suited for distribution centers, shipping departments, e-commerce fulfillment operations, and any trade or commercial environment that requires a lightweight, durable mailing solution. The poly construction resists water and moisture exposure common in warehouse and loading-dock environments. Cases of 250 mailers are practical for moderate to high-volume shipping operations where consistent, reliable packaging is required.

Installation Notes

No tools are required to seal the B911 mailer. Peel the self-seal strip and press the flap firmly against the mailer body to close. Ensure the contents are positioned away from the seal area before closing to maintain a secure bond. Store unused mailers flat in a dry location away from direct heat or sunlight to preserve the adhesive seal strip.
