The carton includes a central panel and a pair of opposed exterior end panels and a pair of interior end panels affixed to the exterior end panels. A pair of supplementary interior end panels are affixed to each of the interior end panels and a supplementary interior end panel flap is affixed to each supplementary interior end panels. The carton has a pair of opposed side panels affixed to the central panel formed with a plurality of spaced apart side panel ventilation holes. A pair of side panel flaps are affixed to each end the side panels and a pair of opposed cover panels with ventilation holes are also affixed to the side panels. Forming the foldable carton involves folding the supplementary interior end panel flaps to overlie the supplementary interior end panels, folding the supplementary interior end panels to overlie the interior end panels and folding the side panel flaps to overlie each other.
