Faster, more cost-effective pack times. Foam/apple trays do not require a polyethylene foam pad in between layers to protect against abrasion. They can be stacked with the fruit in direct contact with the bottom of the foam tray on top of it. This means labor, material, and inventory costs savings due to more efficient packs. Drainage holes. Patented design with built-in channels and drainage holes to allow moisture to run off in hot/humid climates.
