Insulated Bags Range
Our Insulated Bags have been put through some temperature tests to show you how well they perform.
Change Of Surface Temperature During Transportation
The graph below shows what happens with the surface temperature of Frozen Poultry, Chilled Vegetables and Chilled Dairy Products. The products were sitting in a standard cotton “bag for life” in a temperature of approximately 21oC. As you can see after 35 minutes the Vegetables were in the danger zone. The Frozen Poultry entered the Temperature Danger Zone at 65 minutes with the Dairy products following at 80 minutes. To put this into context, from the moment a shopper puts their first product in the trolley to the shopper unloading the car takes approximately 90minutes. By this time all the perishable products would have entered the Temperature Danger Zone.
Ambient Temperature Changes
The following graph shows the ambient temperature changes in a standard 2 ply cool bag and B&G Insulated bags. You can see that the temperature within the B&G 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 same way, 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 B&G’s designed and registered comfort handle takes care off.
We measured the surface temperature of the contents within the bags and after 8 hours, the Surface Temperature of the Vegetable and Poultry within the B&G Insulated Bag had still not entered the Temperature Danger Zone protecting it from altered taste and microbial growth.
