We stock three styles of rigid mailers to accommodate the various stiffness needed for shipping flat products:

• Use Utility Rigid Mailers when cost is your chief concern, but corner and edge protection are still a necessity. Made from 15 point, 100% recycled paperboard with 97% post-consumer content. Pressure sensitive closure and tear-strip opening.

• Our Lightweight Rigid Mailers called Stayflats® Lite are made from 18 point, 100% recycled paperboard. They come with a peel & seal tape closure and a tear strip for opening. Use these mailers when you have bend sensitive documents, but need to save on shipping costs. Great for direct mail, calenders, photographs, postcards, awards, computer software and much more. If extra rigidity is desired use sized right filler pads shown below.

• Our 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.
