THIMM COOLandFREEZE is a modular packaging concept for the temperature-controlled shipment of food products. The innovative packaging design with its insulating cover created from natural fibers ensures effective insulation and the constant refrigeration of fresh products over a period of at least 36 hours. The packaging can be subdivided into different temperature zones with inlays allowing refrigerated and non-refrigerated food products to be shipped together in one delivery. The intensity and duration of the product refrigeration is controlled via the water-based cooling elements which can be reused an almost infinite number of times.
