Our mailing bags 2-ply are made of Kraft paper, and they give a great cover for heavier items, such as ring-binders and catalogues. If the product that needs shipping, such as electronics, textiles or something else, is already in its selling package, a mailing bag made of paper is the right choice for smooth, environmentally friendly and cost-effective packaging and shipping. Printings of your company's logo or other graphic designs are available for the mailing bags, which can also be used as effective marketing tools. Postal bags 2-ply are now available with double closure and a tear open strip. Learn more here.
