How do those silica gel packets “keep things fresh”?
In: Chemistry
They absorb moisture from the air around them. Thus they are used for things that should be kept dry as they’ll mitigate the effects of humidity. They don’t work indefinitely though, so you’re still supposed to keep the product somewhere relatively dry.
They absorb moisture, which will keep the air and hence stuff in the package dry. This would reduce the chances of, say, fungus and other unwanted stuff growing because it doesn’t have the moisture it needs to thrive.
