Bsc Preferred PL21 Packing List Envelopes 1000 Per Case

Product Description

The BSC PREFERRED PL21 is a transparent, pressure-sensitive packing list envelope designed to protect and display shipping documents on the outside of cartons and packages. Each envelope is constructed at 2 mil thickness, providing a tamper-evident, moisture-resistant barrier that keeps packing slips, invoices, and labels clean and readable through the transparent face. The back-loading design allows quick document insertion without compromising the adhesive seal. This product is sold in a case quantity of 1000 envelopes, making it suitable for high-volume shipping and receiving operations.

These envelopes are used in warehouse, distribution, and logistics environments where documents must remain visible and secure on the exterior of shipped goods. The pressure-sensitive adhesive bonds directly to corrugated boxes, poly bags, and other standard shipping surfaces without requiring tools or additional fasteners. The back-loading format is a common choice for operations running high-throughput packing lines.

Document insertion is through the back opening prior to sealing on the package. Store unused envelopes in a cool, dry location to maintain adhesive integrity.
