Excerpts from the report: Eighty percent of U.S. broiler production is shipped ice-packed. In 1966, 70 percent of ice-packed poultry was shipped in wirebound wood-veneer boxes (henceforth referred to as wirebound boxes). The rest of the ice-packed poultry was shipped in water-resistant corrugated fiberboard boxes. The objectives of the present study were to determine: (1) cost of packing and shipping ice-packed poultry in polystyrene and wirebound boxes, (2) poultry shrinkage and ice melt in polystyrene and wirebound boxes, and (3) whether polystyrene boxes are sturdy enough for handling and shipping poultry.
