Insulated shipping containers are crates for temperature-sensitive goods, such as perishable foods, biological materials, pharmaceuticals, or anything else whose shipment could be complicated by high temperatures. Our insulated containers are Styrofoam (expanded polystyrene) refrigerators. These provide superior insulation (R value) for cargoes with extended transit times. With our lightweight, reusable, and recyclable insulated shipping boxes, you can transport your goods securely while preserving their insulation and integrity.
