Why should the frozen CoolPacs not be placed next to the product load?
The liquid within a standard CoolPac changes phase from a solid to a liquid at approximately 0°C, during this change, the CoolPac is able to absorb large amounts of heat energy. If the CoolPac at 0°C or less is in direct contact with the product, then there is a risk that the product may fall below +2°C.
