Wholesale Flat Mailers

Category image Image

Flat chipboard mailers offer a light way to ship, helping to save on postage. These mailers are a great way to ship documents or photos and do not require additional stiffeners. We offer chipboard mailers in a variety of prints as well as tab lock and self seal options. Self Seal flat mailers offer a pull tab tear strip for easy opening. To easily find flat mailers designed for holidays, printed with "do not bend", black in color or different sizes, use the filter options on the left hand side.
