We stock four styles of rigid mailers:
All styles are Recyclable and made from 100% recycled paperboard.

Stayflats Utility Made from .015" thick tan chipboard. Peel & seal tape closure; tear strip opener. Corresponding filler pads.

Stayflats® Lites are made from 18 pt., paperboard. They come with a peel & seal tape closure & a tear strip opener. Use these mailers when you have bend- sensitive documents but need to save on shipping costs. If extra rigidity is desired use appropriate-sized filler pads.

Stayflats® RIGID MAILERS - the original mailers 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 .036" 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.

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.
