The BSC PREFERRED PL440 is a pressure sensitive packing list envelope designed to secure and protect shipping documents attached to the outside of shipments. Constructed from heavy 2 Mil poly material, each envelope features a hot melt adhesive backing that bonds firmly to paper and corrugated surfaces. The envelopes open along the first dimension for easy document insertion and retrieval. This case contains 1000 envelopes, making it a practical bulk supply for warehouses, distribution centers, and shipping operations that process high volumes of outbound freight.
These packing list envelopes are suited for commercial and industrial shipping environments where documents such as packing slips, invoices, or delivery instructions must travel on the exterior of a carton or corrugated box. The pre-printed specialty use messages help identify envelope contents at a glance, supporting faster receiving and sorting workflows. Compatible with both paper and corrugated packaging surfaces, the PL440 fits standard shipping and fulfillment operations across a wide range of industries.
Designed for use with standard paper and corrugated packaging surfaces in commercial and industrial shipping applications. Equivalent to part number S-1683.
Clean and dry the carton surface before applying the envelope to ensure maximum adhesive bond. Peel the adhesive liner, position the envelope on the outside of the shipment, and press firmly across the full backing area. Insert documents before sealing the envelope flap. Avoid applying to wet, oily, or heavily textured surfaces where adhesion may be reduced.
