Tin Foil VS Aluminum Foil: Which is Safer?

Under normal usage, both tin foil and aluminum foil can be safely used. But in certain specific situations, aluminum foil may be safer than tin foil.

Firstly, tin foil is usually coated with a polymer protective coating, which contains a chemical substance called metaformate (BPA), which may penetrate into food and have adverse effects on human health; And aluminum foil does not contain this chemical substance.

Secondly, tin foil is usually thin and easily corroded by food acids or salts, causing metal to penetrate into the food. And aluminum foil paper is stronger and less susceptible to food erosion.

Finally, the production process of tin foil is complex and costly, making it less common in certain regions, while aluminum foil is widely used and more affordable, making it easier to obtain.

In summary, both tin foil and aluminum foil can be used safely, but in some cases, aluminum foil may be more suitable and safer. Users should choose suitable materials based on specific circumstances.
