Abstract: A repulpable moisture resistant protein box having a composite structure with a fluted medium, a top backing board secured to one side of the fluted medium and a bottom backing board secured to the other side of the fluted medium. The backing boards are impregnated with a hydrogenated triglyceride on the wire side and the fluted medium is also impregnated with a hydrogenated triglyceride. The backing boards each have an outer felt side surface coated with styrene acrylic co-polymer. The protein boxes have a higher compression, moisture resistance and are recyclable.

Abstract: A repulpable leak resistant poultry box having a composite corrugated structure with a fluted medium formed with a top backing board secured to one side of the fluted medium and a bottom backing board secured to the other side of the fluted medium, all of which are impregnated with a hydrogenated triglyceride and the backing boards are coated with an acrylic styrene copolymer. In one embodiment, the box has a bottom panel and end panels integral to bottom panel positioned at opposite ends of the bottom panel and separated by a fold line from the bottom panel. The side panels assemblies are integral with the bottom panel with each side panel being separated by a fold line and have a plurality of reinforcing end panels extending from opposite ends of the side panel and integral foldable cover members connected to the side panels by a fold line.
