    Properly Securing Bundles of Flats

    Please note that as of July of 2025, the Postal Service no longer permits using rubber bands and twine or string for securing bundles of flats, with the exception of bundles of First-Class Mail® flats placed in flat trays. All bundles of flats must have two or more cross-strapped bands or be shrink-wrapped with one or more cross-strapped bands, with the exception of newspapers that are placed in a flat tray and entered as exceptional dispatch. Such newspapers may be bundled by using only one strap around the middle of the bundle to prevent damage.
