How to remove words on aluminium foil used in medicine package? Is there any easy way?
Using a wet cloth to wipe it.
Words printed on it is organic matter and can be corroded by concentrated sulfuric acid. Since aluminium plate is protected by oxidation film in its appearance, it's ok to do so. But you should be careful when you operate for plastic plate may also be corroded. Only teflon and high density polyethylene are anti-corrosion, but they are with higher price and therefore won't be used in normal situation.
