Amazon/Morrison's deliver frozen food with ice packs containing some

What liquid are they using and do ice packs have any use once the frozen
food has been delivered? Seems a shame to throw them away.
It is probably "Dry Ice". Frozen Carbon Dioxide. Your freeze°r would need
to beta -78°C to keep it frozen ;-)
Dry ice isn't a fluid.
Check your freezer temperature, it's probably faulty.
