Qualifications or Sales Literature?

Does a qualification test really measure the effectiveness of the packaging?

The qualification time of a packaging system is often seen as its ability to hold a given temperature for a period of time. This may in some ways be true, but does a qualification test really measure the effectiveness of the packaging?

A cardboard box, with no form of cooling or temperature control, can maintain a temperature of 5°C if it is kept in a fridge which is also at 5°C, and it will carry on doing this until the fridge is switched off. To argue that the cardboard box therefore has a validation for such a period would therefore be nonsense. The temperature to which the cardboard box has been exposed has not tested its insulative capabilities.
