Arctic Ice Tundra Reusable Freezer 5-lb Purple Liquid Ice Pack

Tundra series® ice packs are designed to maintain a “freezer-like” temperature in coolers. Tundra series™ has the ability to keep frozen items frozen for extended periods of time. These innovative panels are filled with a unique, high-performance phase change material that has a freezing point of 5 degrees Fahrenheit (-15 degrees Celsius). This unique material absorbs heat instead of the frozen items in a cooler with higher melting points and therefore keeps the frozen items frozen. Simply freeze tundra series® packs at a temperature below 0 degrees Fahrenheit (turn freezer temperature down to lowest temperature if needed) for 24-36 hours or until solid. Working times will vary depending on cooler type and outside temperatures. Store tundra series® in the freezer for instant access when needed.
