Bsc Preferred B870 Poly Mailer Self-seal 500 Per Case

Product Description

The BSC PREFERRED B870 is a polyethylene poly mailer designed to protect shipments from moisture, tampering, and physical damage during transit. Built with high-strength seams, the B870 holds contents securely even when packed at or near capacity. The outer surface is white for easy labeling, while the inner lining is silver. Labels, stamps, and ink adhere directly to the outer surface without additional prep. Closure is handled by a self-seal adhesive strip, eliminating the need for tape. These mailers ship and store as a case of 500 units.

The B870 is suited for distribution centers, fulfillment operations, shipping departments, and supply rooms handling moderate to high parcel volume. The puncture- and tear-resistant construction makes it appropriate for lightweight goods, documents, soft goods, and similar non-fragile items. The self-seal closure speeds up packing workflows without requiring additional equipment or materials.
