Rigid Flat Mailers

We stock three styles of  Flat Rigid Mailers to accommodate the various stiffnesses needed for shipping flat prints & posters:

 Lightweight Rigid Mailers called Stayflats® Lite are made from 18 pt., 100% recycled paperboard. They come with a peel & seal tape closure and a tear strip for the opening. Use these mailers when you have bend sensitive documents, but need to save on shipping costs. 

  Standard Rigid Mailers are the correct choice for shipping matted or mounted posters that are more valuable. The material is heavy duty brown kraft .037" thick or sturdy white clay-coated newsback .028" thick. Bent and crimped corners and pages are a thing of the past when you use these mailers. They come with a tuck-tab closure.

•  Stayflats Plus® RIGID MAILERS - These mailers are available in white clay-coat newsback .028" thick. Mailers come with a peel & seal tape closure and a tear strip for easy opening. Corresponding Filler Pads are linked in each mailer description.

NOTE: When choosing your mailer be sure to take into consideration the thickness of the item being shipped as well as the thickness of any fillers you may choose to use.
NOTE:  Mailers for standard Prints & Posters are shown in this category. We have more sizes not shown here. To view all styles & sizes of Rigid Mailers click here.
