We stock three thicknesses of rigid mailers:


Stayflats Utility™ mailers are our latest rigid mailers. Made from .015" thick tan chipboard. The material is recycled paperboard with 97%
post-consumer content. 100% recyclable. Peel & seal tape closure; tear strip opener. Click here for corresponding filler pads.

Stayflats® Lites are made from 18 pt., 
100% recycled paperboard. They come with a peel & seal tape closure; tear strip opener.  Use these mailers when you have bend sensitive documents, but need to save on shipping costs. Great for direct mail, calendars, photographs, awards, computer software and much more. If extra rigidity is desired use appropriate sized filler pads. Click here for corresponding filler pads.

Stayflats® RIGID MAILERS - the original mailer are the correct choice for shipping flat items when rigidity is the highest priority. These mailers are available in white clay coat or brown kraft. The brown kraft is heavy duty .037" thick board; the white clay coated newsback is .028" thick. The variety of sizes offered (from 5 x 7 through 21 x 27) ensures that whatever you are shipping will have a mailer close in size. Click here for corresponding filler pads.

We offer Corrugated Pads as well as Chipboard Pads for these mailers. Pads are used for additional stiffening, corner and edge protection and buffering between items being shipped. Click on above Filler Pads links to view.
