What Are Catering Dry Ice Packs and How Do They Work?
Catering dry ice packs are flexible multi cell blankets filled with high purity solid carbon dioxide. Quando exposto ao ar ambiente, the CO₂ sublimates directly from a solid to a gas, absorbing heat without turning into liquid. Porque não há derretimento, food stays dry and packaging remains intact. Each cell in the blanket keeps the CO₂ evenly distributed, creating uniform cold across trays or containers. O gelo tradicional derrete em 0 °C, while dry ice holds –78,5 ° C.; gel packs generally hover near –21 °C. This extreme cold means dry ice sheets can preserve frozen foods like ice cream, seafood or meat for extended periods rather than merely chilling them.
The Science of Sublimation and Temperature Control
Durante a sublimação, carbon dioxide absorbs latent heat from the surrounding environment, cooling items inside the insulated container. Ao contrário dos pacotes de gel, which thaw gradually and may leak water, dry ice emits CO₂ gas that escapes through vents in the cooler. This absence of liquid water prevents soggy packaging, bacterial growth and label damage. Because sublimation occurs at a constant temperature (–78,5 ° C.), the cooling effect is remarkably stable until the ice is gone. Modern dry ice sheets come in various sizes: mini sheets para remessas em 24 horas, standard sheets para 48 horas e large sheets para até 72 horas. O formato de folha espalha o frio uniformemente, reducing point contact freezing and making them ideal for delicate pastries or sushi.
CO₂ sólido vs.. Gel Based Dry Ice Sheets
Not all “dry ice packs” are the same. Some products contain pure dry ice (CO₂ sólido); others use super cooled gels or phase change materials but market them as “dry ice sheets.” True CO₂ packs provide intense cooling but can’t be refrozen; once the CO₂ sublimates, there’s nothing left to reuse. Por contraste, gel based packs freeze at about –40 °C and are fully refreezable for sobre 30 ciclos. These gel packs maintain temperatures between –12 °C and –18 °C for up to 48 horas, making them suitable for meal kits that need to stay frozen but not at –78 °C. Choosing between solid CO₂ and gel based packs depends on your product’s sensitivity and the desired temperature range.

Practical Tips and Use Cases
Small receptions (3–6 horas) – For shrimp cocktails and cheese boards, plano 0.5–1 libra (0.3–0.5 kg) de gelo seco por 24 horas. Use mini sheets placed around trays and pre chill foods.
Wedding dinners (6–12 horas) – For steaks, seafood platters and desserts, alocar 2–5 lb. (1–2kg) de gelo seco por 24 horas. Combine dry ice sheets with gel packs for salads and desserts.
Outdoor festivals (12–24 horas) – For BBQ meats and ice cream bars, usar 5–10 lb. (2–5kg) de gelo seco por 24 horas. Place sheets at the bottom of insulated coolers and layer between trays.
Multi day tours or conferences (24–48 horas) – Plan 10–15 lb. (4.5–7 kg) de gelo seco por 24 horas. Use multiple layers of sheets and monitor temperature with sensors.
Exemplo do mundo real: A wedding caterer in 2024 used flexible CO₂ sheets and gel packs to transport 200 guests’ meals across state lines. Ao colocar 5 lb of dry ice per cooler and monitoring temperature with IoT sensors, the caterer kept seafood and desserts frozen for 12 horas, reduced waste by 30 %, and created a dramatic fog effect during service.
Why Are Catering Dry Ice Packs Ideal for Events?
Extended Cooling and Moisture Free Transport
Catering dry ice sheets maintain temperaturas ultrabaixas and prevent moisture from damaging packaging. Ao contrário dos pacotes normais de gelo ou gel, gelo seco sublima diretamente em gás CO₂, saindo Sem resíduo líquido. This means your food stays perfectly dry—even delicate pastries and vacuum sealed entrées arrive crisp and intact. Each sheet can cool for 24–48 horas, whereas gel packs often last only 6–12 horas. For long distance deliveries or multi day events, this extra time is invaluable and reduces the need to restock cooling agents mid event.
Cost Efficiency and Sustainability
Although dry ice may seem pricier at first, it reduces spoilage and food waste, offsetting the cost. Dry ice is produced from captured industrial CO₂, turning emissions into a useful product. Flexible sheets conform to trays and coolers, allowing you to use fewer packs than rigid bricks or gel packs while still maintaining the desired temperature. Advanced gel based dry ice packs introduced in 2025 pode ser reutilizado 30 ciclos and maintain –12 °C to –18 °C for até 48 horas, reducing packaging costs by as much as 75 % and eliminating hazardous materials fees associated with shipping solid CO₂.
Reliability and Even Temperature Distribution
O gelo seco sublima lentamente, providing a consistent low temperature until it’s gone. Multi cell blankets distribute cold evenly across the surface of trays or boxes, preventing warm pockets that could compromise food safety. This reliability gives caterers peace of mind, especially during outdoor events where ambient temperatures fluctuate.
Dramatic Visual Effects
Dry ice doesn’t just keep food cold—it also creates visually stunning fog when exposed to moisture. The fog cascades over serving platters, making seafood displays, chilled desserts and cocktail stations memorable. For weddings, holiday parties or corporate launches, this dramatic element enhances the dining experience and delights guests.
How to Choose the Right Size and Quantity of Dry Ice for Your Event
Determining how much dry ice you need depends on the weight of your food, event duration and insulation quality. Use these guidelines as a starting point:
Weight based ratio – For overnight shipments, usar metade do peso of your payload in dry ice; para 48 horas, usar peso igual; para 72 horas, objetivo para 1.5× the weight.
General formula – For a 24 hour shipment, planejar 5–10 lb. (2.3–4,5 kg) de gelo seco; para 48 horas, usar 10–20 lb (4.5–9 kg). Adjust for ambient temperature, container insulation and food density.
Sugestão de ferramenta interativa – Embedding a calculadora de gelo seco on your website allows users to input meal weight, desired temperature and event duration. The tool outputs recommended dry ice weight and number of sheets, encouraging engagement and reducing guesswork.

Packing and Handling Best Practices for Caterers
Preparing the Container
Use a well insulated cooler or shipping box. Pre chill the container with gel packs or place it in a freezer for an hour before packing. Better insulation means less dry ice needed.
Camada na parte inferior. Place a piece of cardboard or corrugated plastic at the bottom to protect containers from direct contact with extreme cold.
Evenly distribute dry ice sheets. Arrange dry ice sheets across the bottom and between layers of food.
Separate food items. Use additional cardboard or foam layers between dry ice and food to control cooling and make unpacking easier.
Preencher vazios. Fill any empty spaces with crumpled paper or reusable foam blocks to slow sublimation and maintain uniform temperature.
Garanta ventilação. Never seal the cooler completely; dry ice emits CO₂ gas that needs to escape to prevent pressure build up. Vented packaging or a loosely fitting lid is essential.
Manuseio e Segurança
Use equipamento de proteção individual – Always use insulated gloves, long sleeves and safety goggles when handling dry ice to prevent frostbite. Nunca toque no gelo seco com as mãos desprotegidas.
Use pinças ou colheres – Move dry ice using tongs or specialized scoops, not bare hands.
Armazene adequadamente – Keep dry ice in well insulated, vented containers away from living areas. Do not store in glass or airtight containers, which can crack or explode.
Transporte com segurança – Use ventilated vehicles and avoid sealed compartments to prevent CO₂ buildup. Label packages clearly with “Dry Ice” (E 1845) and weight information.
Descarte com responsabilidade – Allow leftover dry ice to sublimate in a well ventilated outdoor area. Nunca descarte gelo seco em pias, toilets or sealed trash bins.
Treine sua equipe – Educate all employees on safe handling, emergency procedures and CO₂ exposure risks. Conduct regular safety drills.
Considerações Regulatórias
Shipping carriers have strict limits on dry ice quantities (muitas vezes 5–10 lb per shipment for consumer deliveries) e exigem rotulagem adequada. Check your carrier’s regulations before shipping. Some event venues also have rules on dry ice use and disposal; always confirm in advance.
Gelo seco vs.. Gel Packs and Other Cooling Options
Both dry ice and gel packs have advantages, and sometimes combining them yields the best results. O gelo seco mantém temperaturas extremamente baixas, often as low as –109,3°F. It lasts longer than gel packs, especially in insulated containers, and leaves no liquid residue. No entanto, it requires special handling and has a lifespan of 12–24 horas per block or sheet in typical shipping conditions. Os pacotes de gel são reutilizáveis, non toxic and come in a range of temperature options; they’re ideal for produce, beverages or shipments to recipients unfamiliar with dry ice. When shipping frozen goods like meats or ice cream, dry ice is usually necessary. For chilled items that must stay between 2 °C e 8 °C, gel packs or phase change materials suffice. Considering materiais de embalagem, shipping rates, reusability and environmental impact will help you decide the right combination.
