The Coolshopper is a thermal cover or insulated thermal packaging system that is especially designed to fit in the well known shopping folding-crates which are used by the consumer to carry the shopping products from the supermarket to their homes. As we all know, the quality of perishable food products (fresh and frozen) is very delicate in which temperature deviations or excursions can cause quality damages causing diseases. This needs to be avoided and explains why supermarkets and food retailers are investing a lot of money and efforts to create a closed cold chain where the temperature is stabilized according to the requirements and regulations. Yet one last part of the cold chain often remains open where the temperature can deviate and this is transport from the supermarket to the consumer. That is why we developed the Coolshopper.
