Packing List Envelopes are an oil-resistant and water-resistant polyethylene envelope for packing slips, invoices, cards, and other shipping documents. This packet has pre-sealed edges, is loaded from the back, and has a synthetic rubber adhesive on the back that is covered by an easily removed paper liner. These envelopes work well in situations where the shipping orders are generated in an office area and later applied to the proper package in the shipping area.
