Mil-Spec Packing List Enclosed Envelopes provide highly visible, secure protection for packing slips, invoices, and shipping documents attached to cartons, poly mailers, and outgoing packages. The fluorescent orange full-face print makes paperwork easy to identify, while the durable 2 mil polyethylene helps protect documents from moisture, dirt, and routine handling. A strong hot-melt adhesive backing keeps the pouch firmly attached, and the side-loading opening allows documents to be inserted quickly and efficiently.
