Is non-stick aluminum foil safe to use on the grill?
I'm not certain what a &quot;non stick aluminum foil&quot; is, something like this?

Whether in the oven, on the grill or anywhere in between, Reynolds Wrap® Non-Stick Foil gets the job done anytime and anywhere. You can cook, cover, freeze and store with ease.

Usually, when using aluminum packets, we cook them on an indirect flame.
If your grill has 2 burners, you close one up and keep the other one open and put the packets on the closed burner side.
It'll act more or less like a regular oven.
The link above says that it can be used (with a link to recipes) for grilling.
