1. A system for coating agricultural cores with a flexible film, the system comprising:
a carrier having an exterior face including a connecting structure and a plurality of core supports recessed relative to the connecting structure, each core support including
a pedestal sized and shaped to support one of the agricultural cores to be coated, the pedestal including an aperture of a first fluid conduit; and
a plurality of bridges which extend between the pedestal and the connecting structure of the exterior face of the carrier, the plurality of bridges being separated by a plurality of apertures of a second fluid conduit; and
a vacuum system in fluid communication with the first fluid conduit and the second fluid conduit, wherein the vacuum system pulls the flexible film toward the pedestal.
