Why Best Mailers qualify as USPS Flats, and other packaging options don’t

Polybag
USPS rules state that contents can not shift more than 1” within a Automated Flat. Polybags have no structure, causing contents to shift within the package
USPS rules state that packaging needs to be flexible on both the X and Y axis. Boxes, by design, are not flexible
Box
Bubble Mailer
USPS Flats must be less than ¾” thick. Bubble mailers add unnecessary thickness, and do not stop contents from shifting.
Designed to start flat and stay flat. These mailers do not expand to fit garments and are difficult to keep merchandise flat while inserting.
Conventional Paperboard Mailer
