What Are Disposable Dry Ice Packs for Camping?
Dry ice pack basics. A disposable dry ice pack is essentially a sealed pouch filled with solid carbon dioxide (Co₂). Contrairement à la glace ordinaire, qui fond dans l'eau, dry ice sublimates directly into gas when it warms above −78.5 °C. This process absorbs a large amount of heat without leaving a puddle, making it ideal for campers who want to keep gear dry and avoid soggy food. Because the packs are sealed, they prevent direct contact between the dry ice and your food, reducing the risk of freezer burn and frostbite injuries. Most manufacturers pre freeze the packs, so you simply place them in your cooler and let the sublimation do the work.
Why dry ice is colder than water ice. Carbon dioxide freezes at a much lower temperature than water. The solid CO₂ inside a dry ice pack maintains temperatures around −78.5 °C (−109.3 °F). En comparaison, conventional ice remains at 0 °C (32 °F) until fully melted. This extreme cold means a properly insulated cooler can keep meat rock solid for up to 72 heures, provided there is enough dry ice and limited air gaps. Packs de gel, en revanche, usually hover near the freezing point and are better for chilling rather than freezing.
Forms of Dry Ice Packs
Blocks versus nuggets. Dry ice packs are often sold in two forms: block style packs or small nugget packs. Blocs, which look like bricks, sublimate slowly and deliver long lasting cold—ideal for multi day camping or transporting frozen meats. Nuggets or pellets release cold more quickly but don’t last as long; they’re useful when you need to bring down the temperature fast on a shorter trip. Because nuggets distribute around your food more easily, they can provide more even cooling.
| Formulaire | Plage de température | Durée | Avantage pratique |
| Block Pack | Holds –78.5 °C to –20 °C | 48–72 hours in a well insulated cooler | Maintains ultra low temperatures for multi day trips; fewer packs needed |
| Nugget Pack | Quickly reaches –78.5 °C but warms faster | 12–36 hours depending on load | Ideal for short trips or quick chill; easy to distribute around food |
| Eco Friendly Sheet | –78,5 °C à –20 °C | 24–72 heures | Flexible biodegradable film conforms to cooler shape; reduces plastic waste |
Blocs, Sheets and Biodegradable Options
In addition to block and nugget packs, 2025 has seen the rise of eco friendly dry ice sheets. These flexible sheets consist of many small cells of dry ice encased in biodegradable film made from paper, cellulose or compostable polymers. They maintain ultra cold temperatures for up to 72 heures, conform to irregular spaces and leave no liquid residue. Each pound of dry ice produces roughly 8.3 cubic feet of CO₂ gas, so packaging must allow venting. Compared to traditional plastic coated packs, biodegradable sheets eliminate plastic waste and use CO₂ often captured from industrial processes.
How Do Dry Ice Packs Compare with Gel Packs and Regular Ice?
Temperature maintenance and duration. Dry ice packs maintain much lower temperatures than gel packs or ice. While dry ice can keep frozen goods at –109.3 °F for days, gel packs are designed to stay around 0 °C (32 °F) and are better suited for cooling rather than freezing. Ice packs begin to melt as soon as the ambient temperature rises above freezing and leave a pool of water behind. Well insulated coolers combined with dry ice can preserve frozen food for several days, whereas gel packs may only last 24–48 hours in similar conditions.
Safety considerations. Handling dry ice requires heavy gloves and careful ventilation because it can cause frostbite on contact and emits CO₂ gas. Packs de gel, by comparison, are non toxic, reusable and don’t require special handling. Cependant, gel packs can leak if punctured, potentially contaminating food. Dry ice leaves no liquid and won’t make your cooler soggy, but you must ensure that gas can escape by cracking the lid or loosening the drain plug.
Impact environnemental. Dry ice is environmentally friendly because it uses CO₂ that is often reclaimed from industrial processes and sublimates into gas without water consumption. But production and transport can be energy intensive. Les packs de gel sont réutilisables, but they are typically encased in plastic and may contribute to waste if not recycled. Eco friendly dry ice sheets made with biodegradable film address this issue by eliminating plastic and repurposing captured CO₂.

How Much Dry Ice Do You Need for Camping?
Sizing based on cooler volume. To determine how many disposable dry ice packs to bring, consider your cooler’s size, trip length and outside temperature. A general rule of thumb is to use around 10 kg (4.5 kg) of dry ice per day for a 50 quart (47 L) glacière. For weekend camping in summer, a well packed 60 quart cooler with about 20 lb of dry ice can keep meat rock solid for 48 heures. When flying, you must limit each cooler to 5.5 kg (2.5 kg) to comply with FAA regulations.
Adjust for trip duration and conditions. If the weather is hot or you open the cooler often, increase the amount of dry ice. Fill empty spaces with towels or newspaper to reduce sublimation and extend cooling time. Pre chill all food and the cooler itself to lower the initial heat load and reduce dry ice consumption.
Cooler Size and Dry Ice Weight Guide
| Taille plus froide (qt/L) | Poids de glace sèche (lb/kg) | Environ. Hours Below 32 °F | What It Means for Campers |
| 20 QT / 19 L | 5 kg / 2.3 kg | ~ 24 h | Perfect for overnight or day trips—fits within TSA limits |
| 50 QT / 47 L | 10 kg / 4.5 kg | ~ 48 h | Ideal for two day camping or road travel |
| 80 QT / 76 L | 15 kg / 6.8 kg | ~72 h | Suited to long weekends or group trips; needs robust cooler |
Choosing the Right Cooler
Not all coolers are built to handle dry ice. Thick walled hard coolers (particularly roto molded models) and robust styrofoam boxes are best because they insulate well and tolerate extreme cold. Avoid air tight latches; CO₂ gas must vent safely to prevent pressure build up. Thin picnic coolers can crack at –109 °F (–78 ° C) due to the intense cold. Look for the following features:
Gasket seals with slight venting: Allows gas to escape without letting in too much warm air.
Drain plug with vent: Loosen it slightly to relieve pressure.
At least 2 inch (5 cm) wall insulation: Reduces sublimation and saves on dry ice.
UV resistant shell: Protects your cooler from sun damage at campsites.
Safe Handling and Packing Techniques
Ventilation is essential. La glace sèche sublime dans le gaz co₂, which is heavier than air and can displace oxygen. Always use dry ice in a well ventilated space. Keep the cooler in a shaded area and crack the lid or drain plug to let gas escape. Never store dry ice in an airtight container or fully sealed freezer; pressure build up can cause the container to rupture.
Équipement de protection. Direct contact with dry ice can cause frostbite. Always wear gloves or use a cloth when handling packs. Protect your eyes with safety glasses if cutting or splitting blocks. Keep dry ice away from children and pets.
Coucher intelligent. Start by pre freezing your food and drinks and chilling the cooler itself. Place a piece of cardboard or towel at the bottom to protect the liner, then lay a dry ice slab or sheet. Add a newspaper layer to cushion items and pack food tightly from largest to smallest. For even cooling, place another dry ice slab on top. Loosen the drain plug or crack the lid a quarter inch during transport to vent the gas.
Travel regulations. When flying, label your cooler “Dry Ice (2.5 kg or less)” and inform the airline at check in; TSA officers can inspect your container. If you’re driving, crack a window to prevent CO₂ accumulation in the cabin. Store the cooler in a ventilated area and never in a sealed basement or trunk.

Astuces et conseils pratiques
Separate frozen and fresh foods: Use partitions or separate coolers; dry ice can freeze fresh produce quickly.
Keep frequently used items on top: Minimize cooler openings to slow sublimation.
Permettre à la glace sèche de sublimer l'extérieur: After your trip, let any leftover dry ice dissipate in a well ventilated area; never pour it down a drain.
Combine regular ice with dry ice: Place water ice above the dry ice to keep it frozen longer; this creates a temperature gradient for items that only need to be chilled.
Use a dry ice calculator: Many camping suppliers offer online tools to estimate how much dry ice you need based on cooler size, outside temperature and trip length.
Exemple du monde réel: A 55 quart roto molded cooler packed with 12 lb of dry ice and 20 lb of frozen meals stayed below 20 °F for 60 hours on a June RV trip. This shows how proper packing and ventilation can extend the cooling life beyond two days without external power.
Environmental Considerations and Sustainability
Biodegradable films and repurposed CO₂. Modern dry ice packs and sheets use biodegradable films made from paper, cellulose or compostable polymers such as PLA and PBAT. These materials decompose naturally and reduce plastic waste, addressing concerns about conventional gel pack casings. The CO₂ inside many dry ice packs is often captured from industrial by products or biogas plants, lowering reliance on fossil fuels and turning waste gases into useful cooling.
Comparing waste profiles. Traditional gel packs, while reusable, eventually need disposal and are commonly wrapped in non recyclable plastic. En revanche, eco friendly dry ice sheets leave no waste aside from the biodegradable film and avoid water consumption because dry ice sublimates into gas. Studies highlight that packaging waste reductions of up to 60 % and cost savings of 40 % are possible when companies switch to sustainable dry ice solutions.
Market trends. The global cold chain packaging market grew from $31.69 milliards en 2024 à $36.02 milliards en 2025, et devrait atteindre $63.48 milliards 2029. Demand is driven by e commerce, biologics shipments and the rising popularity of meal kits and outdoor recreation. Consumers are also paying attention: à propos 43 % consider packaging sustainability when making purchases. Regulations such as California’s PFAS law AB 347 and extended producer responsibility (EPR) legislation push manufacturers to eliminate hazardous additives and invest in eco friendly materials.
