Sustainable-Eco Packing List Envelopes provide a secure way to attach packing slips, invoices, and shipping documents while incorporating recycled material into your packaging process. Made from 100% recycled, green-tinted polyethylene, each pouch helps protect paperwork from dirt, moisture, and routine handling. A strong hot-melt adhesive backing attaches securely to cartons, mailers, and poly bags, while printed environmental messaging highlights the recycled-content construction.
