Our Multi-depth Mailers are made from sturdy 200-pound-test natural kraft corrugated cardboard. We have added new mailers that accommodate thicker books - some up to 4" thick. Mailers come with scores at variable depths - indicated on each mailer below. Measure the length, width and thickness of your product to calculate the best fit.
Stayflats Fit® Mailerscan be used flat or expand up to 1-1/4" or 2". They are made from 100% recycled paperboard (.020" or .028" thick) with 90% post consumer content. They come with a peel-and-seal closure and a pull strip opening. These flexible mailers have strong center seam construction; 360º perimeter protection and score lines on all four sides that allow for uniform expansion.
Use corrugated filler pads if additional protection is needed.
