The BSC PREFERRED PL4 is a pressure-sensitive packing list envelope designed to secure and protect shipping documents on the outside of packages. Constructed from 2 mil polyethylene, each envelope provides a clear, durable enclosure for packing lists, invoices, or other paperwork. A hot melt adhesive backing delivers strong adhesion to both paper surfaces and corrugated cardboard. Envelopes open along the first dimension for easy document insertion. Sold in cases of 1000 units, the PL4 is a standard choice for shipping departments, warehouse operations, and fulfillment teams managing consistent outbound volume.
These envelopes are suited for residential and commercial shipping applications wherever documents must travel attached to the exterior of a shipment. Common use cases include distribution centers, manufacturing facilities, and supply houses that ship trade materials. The poly construction resists moisture and tearing during transit, keeping documents legible on arrival. The pressure-sensitive adhesive activates on contact, eliminating the need for additional tape or adhesive application tools.
Designed as a standard packing list envelope for use on paper and corrugated packaging materials common in shipping and distribution operations.
Peel the release liner to expose the adhesive and press firmly onto a clean, dry surface of the package. Apply to corrugated or paper surfaces free of dust, grease, and moisture for best adhesion. Insert the document before sealing the envelope flap. No special tools are required for application.
