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. When exposed to ambient air, the CO₂ sublimates directly from a صلبة إلى غاز, absorbing heat without turning into liquid. Because there’s no melting, food stays dry and packaging remains intact. Each cell in the blanket keeps the CO₂ evenly distributed, creating uniform cold across trays or containers. يذوب الجليد التقليدي في 0 درجة مئوية, while dry ice holds -78.5 درجة مئوية; 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
أثناء التسامي, carbon dioxide absorbs latent heat from the surrounding environment, cooling items inside the insulated container. على عكس حزم الهلام, 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 درجة مئوية), the cooling effect is remarkably stable until the ice is gone. Modern dry ice sheets come in various sizes: mini sheets for 24 hour shipments, standard sheets ل 48 ساعات و large sheets حتى 72 ساعات. The sheet format spreads cold evenly, reducing point contact freezing and making them ideal for delicate pastries or sushi.
Solid CO₂ vs. Gel Based Dry Ice Sheets
Not all “dry ice packs” are the same. Some products contain pure dry ice (CO₂ الصلبة); 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. By contrast, gel based packs freeze at about –40 °C and are fully refreezable for زيادة 30 دورات. These gel packs maintain temperatures between –12 °C and –18 °C for up to 48 ساعات, 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.

Real world example: A wedding caterer in 2024 used flexible CO₂ sheets and gel packs to transport 200 guests’ meals across state lines. By placing 5 lb of dry ice per cooler and monitoring temperature with IoT sensors, the caterer kept seafood and desserts frozen for 12 ساعات, 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 ultra low temperatures and prevent moisture from damaging packaging. على عكس عبوات الثلج أو الجل العادية, dry ice sublimates directly into CO₂ gas, مغادرة لا بقايا سائلة. 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 ساعة, whereas gel packs often last only 6-12 ساعة. 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 can be reused over 30 دورات and maintain –12 °C to –18 °C for حتى 48 ساعات, reducing packaging costs by as much as 75 % and eliminating hazardous materials fees associated with shipping solid CO₂.
Reliability and Even Temperature Distribution
Dry ice sublimates slowly, 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, يستخدم half the weight of your payload in dry ice; ل 48 ساعات, يستخدم equal weight; ل 72 ساعات, هدف ل 1.5× the weight.
General formula – For a 24 hour shipment, خطة على 5-10 رطل (2.3-4.5 كجم) من الجليد الجاف; ل 48 ساعات, يستخدم 10-20 رطل (4.5-9 كجم). Adjust for ambient temperature, container insulation and food density.
Interactive tool suggestion – Embedding a dry ice calculator 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.
