The only zip lock bags available in local stores for me are labelled that they are supposed to be used for refrigerating food.
Is it possible to know whether those bags are safe to put in water temps near or at boiling temperature or not ?
Is there some sort of experiment or indication that would suggest that the bags are BPA-free and EA-free ?
Can we assume that bags that are made for food, are supposed to be safe regardless of the temperature ? (up to 100c only though)
