How long does it take to freeze PackIt bags?
PackIt bags require a full 12-14 hours in the freezer to achieve optimal cooling power. For faster freezing, unfold the PackIt and lay it flat in the rear of the freezer (close to the ice maker if applicable). If you’re freezing more than one PackIt at a time, it may take longer for the bags to fully freeze. Space them as far apart from each other as possible in the freezer and allow for at least 14 hours of freezing time.
How long do PackIt bags stay frozen?
PackIt is designed to keep food and drinks cold for several hours under normal room-temperature conditions (70°F/21 °C). However, the number of hours at which the bag itself stays frozen depends on external temperatures and use. Expect shorter cooling power in warm environments, particularly during the summer months. Also, if you open your PackIt frequently, it won’t stay cool quite as long. You can extend the cooling power of your PackIt by filling it with foods and drinks that are already frozen.
Can I keep hot food or a hot thermos in my PackIt?
A frozen PackIt is not optimal for a hot thermos. However, an unfrozen PackIt will insulate and keep hot items warm.
