The BSC PREFERRED PL442 packing list envelopes are pressure-sensitive document holders designed to secure and protect paperwork attached to the outside of outbound shipments. Constructed from heavy 2 mil poly, each envelope is pre-printed with "Packing List Enclosed" on the panel face for quick visual identification at receiving docks and freight hubs. Hot melt adhesive backing delivers strong, reliable adhesion to both paper and corrugated surfaces. Envelopes open along the first dimension. These are sold in cases of 1000 units and are a standard item for shipping and warehouse operations teams.
These envelopes are suited for distribution centers, fulfillment operations, manufacturing facilities, and any shipping department that routes packages through standard parcel or freight carriers. The pre-printed face eliminates the need for handwritten labeling or separate printed inserts, speeding up the pack-and-ship process. Their adhesive backing bonds securely to cardboard boxes, poly mailers, and paper-wrapped packages without requiring additional tape or tools.
Designed as a direct equivalent to part number S-6219. Suitable for use on standard corrugated shipping boxes, paper-wrapped packages, and poly mailer surfaces in typical parcel and freight shipping workflows.
Insert documents before peeling the adhesive liner and pressing the envelope firmly onto a clean, dry surface. For best adhesion, apply to surfaces free of dust, oil, and moisture. In cold-storage or refrigerated shipping environments, verify adhesive performance before committing to full case usage. No tools are required for application.
