Dry Ice

Dry ice is a great addition to ice packs.
Dry ice is so cold the ice packs stay frozen longer and helps with keeping food frozen during shipment.

Guess it worked, fish was frozen when received, dry ice was gone, but regular ice packs were well frozen.

Fish was cold and frozen even though we’ve received it on a hot Florida day

FedEx ended up delaying my package by a day and I’m thankful I ordered the extra dry ice.

My seafood order arrived frozen in Florida thanks to the packaging and dry ice.
