How to Keep Your Ice Packs Cold for Longer
If you're planning an exciting outdoor adventure, you need to make sure your food and drinks are fresh and safe when you're ready to enjoy them. The following guide on how to keep cooler bags cold can help you keep your food and drinks cold for as long as possible.
1. Pre-cooling
Before you start packing, make sure the cooler bag and items are as cold as possible. For example, don't take a cooler bag out of a hot car and start loading right away. If the bag feels warm, cool it down with cool cubes or ice before considering filling the bag with food and drinks. Likewise, you should take perishable foods and drinks straight from the refrigerator so they are cold to begin with. The colder the contents and waterproof cooler bag to begin with, the more likely it will stay cold for longer.
2. Fill the space
Another critical step in how to keep a cooler bag cold is to prevent as much warm air as possible from filling the bag. That's why it's important to fill as many voids as possible with ice cubes or anything frozen.
3. The content ratio of ice cubes
When it comes to keeping cooler bags cold, more ice cubes keep items chilled for longer. So, depending on how long you plan to be out, you can pack more ice. Some cool ice cubes will keep your picnic food cool throughout the day, however, if you want to ice your drinks then we recommend using twice as many ice cubes as the contents.
4. Keep the bag zipped up and out of direct sunlight
If possible, keep the bag in a cool place out of direct sunlight. Of course, depending on where you are, this may not always be possible, but the cooler you can keep the bag, the longer the ice will last. Also, please pay attention to tighten the zipper to prevent hot air from entering and cold air from entering.
