Why do we need to condition the CoolPacs at factory ambient temperature?
To ensure that the CoolPac is completely frozen, the temperature to which it is conditioned must be below its point of phase change. At the point of removal from the freezer, it can become necessary to allow the CoolPac to warm slightly at factory ambient, bringing it closer to its point of phase change, as this will lessen the impact of its introduction into the control temperature package. This conditioning period prevents the product falling below +2°C.
