What are the advantages of aluminium wrapping foil?
The aluminium wrapping foil is divided into glossy surface and matte surface. The glossy surface can better absorb external heat and help food to be heated evenly. When you wrap food, the matte surface should be in contact with food, so that the heat is evenly distributed on the surface of the food, shortening the cooking time.

Why is it important to know the concentration of aluminium in a pot?
Given all of these proven risks, it’s important to determine the aluminium concentration when cooking. Pots and other cookware tend to be oxidised, providing an inert layer that prevents the aluminium from leaching into food. The problem is that when you scrub your pots after cooking, that layer is worn away and the aluminium can seep ...
What is aluminium used for?

The hot air is not circulated due to the presence of aluminium sheet. 2) The layer of aluminium which surrounds the food also encloses a layer of air , which provides excellent insulation to ...

3) Aluminium being a shiny surface reflects back most of the radiation from the food back and further prevents any heat loss.
Is aluminium a good conductor?
Aluminium being such a good conductor, how is it possible that it is helping me keep my food warm ?? Because ultimately it should conduct the heat that is inside to the outside for exchange and should have no effect (maybe even cool it faster by increasing the surface area).
Does a plastic bag absorb heat?
Yes it reflects radiate heat well (like other metals, and it's cheap) and contains and stops some insulating air movement (though a sealed plastic bag would do that part better), but it also crumples a lot, somewhat sturdily (which makes it easier to close than like a piece of paper that you would probably have to fold properly), so its points of contacts with the food are reduced (which traps more air between all around it and the food than other methods generally), so this gives less chance for conductive heat transfer, as opposed to like a metal bowl (which if you ever try to from you will know how hot it gets from heat conduction).
Is Aluminium foil harmful to health?
