Arctic Ice Tundra Series Reusable Cooler Pack, 5-Pound
Arctic Ice maintains lower temperatures longer than ice or “blue” ice substitutes. This cooler insert’s reusable active ingredient, PureTemp is a non-toxic, biodegradable phase-change material (PCM) derived from plants. When Arctic Ice approaches its melting point (that’s the phase change) it begins absorbing more heat while stubbornly refusing to warm up. It holds a constant, pre-defined temperature until the entire cooler pack finally thaws. The Alaskan Series freezes at 1 Degree Celsius (33.8 Degrees Fahrenheit) and efficiently keeps food and drinks chilled much longer than the same volume of ice. For optimal performance, freeze Alaskan packs in any household freezer for at least eight hours prior to use.

(We have about 15 or so of these in the two sizes.) Definitely not a dry ice replacement as they claim to be. After about 20+ cycles, they just don’t freeze as cold anymore or stay frozen as long. I…
Place in a deep freezer (-10/-20 degrees F) the work great. Also
Keeps breastmilk frozen These are awesome!! I went on a 2.5 hour plane ride with these in a checked bag with frozen breastmilk and the breastmilk stayed frozen!! I put them in the freezer 36 hours prior and set my freezer as cold as it would go. Right before leaving my house, I put 2 ice packs in the bottom of an insulated lunch box, put 7 bags of frozen milk, then 1 more ice pack on top. Then i put the entire lunch box inside another insulated bag and put it in my checked luggage. I arrived and found my milk was…
