Factors Affecting How Long Dry Ice Lasts

The time that dry ice will last in a cooler or other container can vary based on several factors.

Amount of Dry Ice Used

The amount of dry ice used is one of the most important things that affects how long it lasts. The longer dry ice lasts, the more of it is used.

A good rule of thumb for a normal cooler is to use about 10 to 20 pounds of dry ice every 24 hours. Using more dry ice than this can extend the lifespan even further.

Size and Insulation of the Cooler

The size and insulation of the container used to hold the dry ice can also significantly impact how long it lasts. A larger container will require more dry ice to maintain the same temperature.

Additionally, a well-insulated container will help keep the cold air inside for longer, which will also help the dry ice last longer.

Ambient Temperature

The ambient temperature outside the container can also affect how long dry ice lasts. The warmer the temperature, the more quickly the dry ice will sublimate.

For this reason, storing the container in a cool and shaded area is important to avoid leaving it in direct sunlight.

Frequency of Opening and Closing the Container

Opening and closing the container frequently can cause the cold air to escape, reducing the dry ice’s lifespan.

Type of Items Being Stored

The type of items being stored can also affect how long dry ice lasts. For example, items that are already frozen will require less dry ice to keep them cold.

On the other hand, items not already cold may require more dry ice to maintain a consistent temperature.


Altitude can also have an impact on how long dry ice lasts. The air pressure is lower at higher levels, which can cause dry ice to turn into water more quickly.

If the container is taken to a place with a high altitude, you may need to use more dry ice to make up for it.

Pre-Chill Your Cooler

Another way to extend the lifespan of your ice is to pre-chill your cooler. By dropping the cooler’s temperature before putting ice in it, you can create a colder environment to help the ice melt as slowly as possible.

To prepare your cooler for ice, put it somewhere cool for a few hours before adding ice.

Using Larger Blocks of Ice Instead of Cubes

Although ice cubes of a smaller size may appear preferable, they melt much faster than bigger ice blocks. Consider using larger blocks instead of smaller cubes to make your ice last longer.

These larger blocks will melt more slowly and help keep the cooler’s temperature colder for longer.

Use Dry Ice With Regular Ice

Another way to extend the lifespan of your ice is to use dry ice with regular ice. Since dry ice is so much colder than conventional ice, it can help maintain your cooler’s temperature for much longer.

Dry ice can be used in conjunction with regular ice by being placed at the bottom of the cooler and then regular ice being added on top.

Don’t Empty Water as the Ice Melts

As your ice melts, it will create a layer of water in your cooler. While it may be tempting to empty this water, it can cause your ice to melt more quickly.

The layer of water acts as an insulator, helping to keep the temperature of the cooler colder for a longer period.

How To Store Ice To Extend Its Shelf Life?

How to store Dry Ice to extend its shelf life

It is important to know the shelf life of packing. To extend the shelf life of ice, it must be properly stored and handled. Dry should be stored in a cooler. An insulated cooler with an open lid is the best option for dry last storage.

However, styrofoam containers are beloved in logistics for more than their insulation performance. They are also extremely lightweight and affordable.
