The ideal location for a time-temperature indicator that will be viewed and interpreted by a consumer is clearly on the top surface of the package.  This placement of the monitoring label may situate it on a thin bridge of film material that is not in direct contact with the mass of the product itself. There is some validity to the conclusion that the label itself is not monitoring the product, rather it is monitoring the film and the adjacent air temperature environment (both inside the package and outside).  This can be an important issue if the case ready product itself is subjected to large air temperature variations in handling and in retail display. Generally, the product temperature and internal air temperature  will come to an equilibrium after a relatively short period of time.  If external air temperature changes are not large and frequent,  then the "free floating" position of the temperature label is not too important.  Air temperature changes and product temperature changes will tend to balance out.  (Ask to have a copy of our technical pages for research data that is pertinent to this issue.)
