Insulated Bags - Test Results
What happens to the surface temperature of our food during a shopping trip?
- after 35 minutes the vegetables were entering the danger zone.
- after 65 minutes the frozen poultry also entered the danger zone
- at 80 minutes the dairy products followed.
Ambient Temperature Changes
The following graph shows the ambient temperature changes in a standard 2 ply cool bag compared with an Insulated bag from InsulatedBags.Online. You can see that the temperature within our Insulated Bag dropped sharply after closing the bag, and the temperature stayed steady outside the Temperature Danger zone for nearly 4 hours. The competitors 2-Ply bag did not perform in the sameway, and you can see that the ambient temperature was only marginally lower than the outside temperature, indicating that the thermal insulation was not very good. The other observation was that the closure mechanism used did not keep the air locked in the bag – something that our comfort handle takes care off.
We measured the surface temperature of the contents within the bags and after approximately 4 hours, the Surface Temperature of the Vegetable and Poultry within the Insulated Bag had still not entered the Temperature Danger Zone, protecting it from altered taste and microbial growth.
