What is a kitchen dry ice pack sheet and how does it work?
Dry ice pack sheets are flexible blankets filled with solid CO₂ cells that maintain ultra low temperatures without leaving water behind. Each cell contains compressed CO₂ that sublimates from solid directly to gas, absorbing 571 kJ of heat per kilogram and maintaining surface temperatures around –78.5 °C for up to 72 Std.. Unlike traditional dry ice blocks, the sheet design allows it to wrap around irregular items and distribute cold evenly, eliminating hot spots inside the cooler. Because no liquid forms during sublimation, there is no soggy mess—just dry, cold air circulating around your food.
In der Praxis, a dry ice sheet behaves like a tile of deep freeze power. When you place one in an insulated cooler, CO₂ gas slowly vents out of the perforations, flooding the space with cold vapor. This vapor sinks to the bottom because it is heavier than air, enveloping your frozen goods. The sheet’s plastic film prevents direct contact with the CO₂, so it is safer than loose pellets or blocks, which can burn skin on contact. Das heißt, always handle the sheets with gloves or tongs to protect your hands.
Key properties of dry ice pack sheets
| Eigentum | Beschreibung | Praktische Bedeutung für Sie |
| Temperaturbereich | Maintains –78.5 °C to –20 °C | Keeps ice cream, seafood and meat solid; too cold for salads |
| Dauer | 6–72 hours depending on thickness and load | Suitable for 1–3 day trips or delivery cycles |
| Rückstand | Keine Flüssigkeit; sublimates to gas | No mess in your cooler; easier clean up |
| Wiederverwendbarkeit | Einmalgebrauch (CO₂ dissipates) | Plan just enough sheets; cannot be refrozen |
| Best uses | Gefrorene Lebensmittel, Eiscreme, Arzneimittel | Ideal für Essenssets, Camping, emergency cold storage |
Dry ice pack sheets are different from gel or water packs. Gel packs typically maintain 0 ° C bis 4 °C for 24–48 hours and are reusable. Water packs are inexpensive but provide only a few hours of coolness and create moisture inside your lunch box. We will compare these options in detail later.
How do I choose the right dry ice sheet for your kitchen?
Choosing the right sheet size and weight ensures your foods stay frozen without wasting material. Start by estimating how much product you need to keep cold. A simple rule of thumb is to match the weight of dry ice to the weight of your frozen goods for up to 24 Std.. Für längere Dauer, you need more dry ice: approximately 1–1.5 kg per 1 kg of product for 24–48 hours and up to 2 kg pro 1 kg for shipments lasting 48–72 hours. Each kitchen dry ice sheet is labelled with its mass per square metre, so you can calculate the total weight.
Sizing and layering
| Situation | Sheet thickness | Dry ice needed (per kg of food) | Bedeutung für Sie |
| Kurztrips (≤24 h) | 12 mm | 1 kg per kg of product | Ideal for day hikes or day trip deliveries |
| Medium trips (24–48 h) | 12–18 mm or two layers | 1–1.5 kg per kg | Suitable for two day shipping or road trips |
| Lange Reisen (48–72 h) | 24 mm | Bis zu 2 kg per kg | Use for long distance shipments or emergencies |
When packing your cooler, place the dry ice sheet on top of the frozen goods because cold air sinks. If you are shipping delicate items like seafood, interleave a piece of cardboard or newspaper between the dry ice sheet and the food to act as a buffer. Never pack dry ice in an airtight container; sublimation produces CO₂ gas that needs to escape. To avoid hot spots, use multiple small sheets instead of a single block so the cold is distributed evenly.
Combining dry ice with gel or PCM packs
In many kitchen scenarios, you want both frozen and chilled zones in the same cooler—for example, frozen steaks and crisp salad. Hybrid packing achieves this by combining dry ice sheets with Phasenwechselmaterial (PCM) Gelpackungen. Dry ice provides ultra cold conditions while gel packs maintain moderate temperatures (2–8 ° C), preventing sensitive items from freezing. Place the gel packs near the chilled items and separate them from the dry ice with cardboard. This layered approach extends the life of both cooling agents, because the gel packs absorb some of the sublimation heat and slow down the dry ice consumption.
What are the safety rules when using dry ice pack sheets?
Dry ice is extremely cold and requires careful handling. Contact with bare skin can cause frostbite, so always wear insulated gloves or use tongs when placing or removing the sheets. Avoid breathing concentrated CO₂ gas; use dry ice only in well ventilated areas to prevent oxygen deficiency. Never store dry ice in a sealed container because the expanding gas can cause a dangerous pressure build up. Shippers must include vent holes or gas permeable membranes so that CO₂ can escape, especially when shipping by air where strict regulations apply.
Essential safety checklist
Tragen Sie Schutzausrüstung: Use thick gloves, goggles and long sleeves when handling dry ice sheets. Direct contact can cause severe cold burns.
Ventilation matters: Use coolers with loose fitting lids or vented plugs. Never place dry ice in an airtight thermos or sealed plastic box.
Keep out of children’s reach: Dry ice can injure curious kids and pets. Educate family members about the hazards.
Transport responsibly: Transportieren Sie keine großen Mengen Trockeneis in geschlossenen Fahrzeugen. CO₂ gas can accumulate and cause dizziness or suffocation. Crack the windows during transit.
Dispose of it safely: Let unused dry ice sublimate in a well ventilated outdoor area away from people and pets. Do not dispose of it down sinks or toilets as extreme cold can damage plumbing.
Regulatory considerations
Dry ice shipments are regulated because CO₂ is classified as a hazardous material (Und 1845). Air shipments have strict weight limits; typically no more than 2.5 kg (5.5 lb) per package is allowed without special documentation. Packages must be labelled with the net weight of dry ice and a hazard diamond. For ground shipments, rules are less stringent but ventilation and labeling remain essential. Always check current airline and courier regulations before shipping.
How do dry ice sheets compare with gel packs and water packs?
Selecting the right cooling medium depends on your temperature target, duration and budget. Dry ice pack sheets provide the coldest temperatures (–78,5 °C) and leave no moisture, but they are single use and require safety precautions. Gel packs contain phase change gel that freezes around 0 °C and maintains chilled conditions (2–8 ° C) für 24–48 Stunden; they are reusable and safe to handle. Water packs are simply frozen water in plastic pouches. They are inexpensive but melt quickly and create wet conditions inside coolers.
Comparative overview

| Temperaturbereich | –78.5 °C to –20 °C | 0 ° C bis 4 °C | 0 ° C bis 15 °C |
| Kühldauer | 6–72 h depending on thickness | 24–48 h (can extend with insulation) | 4–6 h for lunch boxes |
| Rückstand | Keiner (sublimates to gas) | Slight moisture when gel thaws | Significant water as ice melts |
| Wiederverwendbarkeit | NEIN; einzelne Verwendung | Ja; can be refrozen 100+ mal | Ja; but prone to leaks |
| Typical uses | Gefrorene Lebensmittel, Arzneimittel | Mahlzeiten, Lebensmittel, Impfungen | Picknicks, Lunchboxen |
| Kosten & Nachhaltigkeit | Höhere Kosten; CO₂ shortages may occur | Mäßig; reusable reduces waste | Niedrige Kosten; but short life increases waste |
When to choose dry ice: Opt for dry ice sheets when you need to keep products below freezing for extended periods—such as transporting ice cream, frozen meats or biological samples over two or more days. Dry ice is also ideal when you want to avoid any moisture inside the container. Jedoch, factor in the cost of CO₂, potential supply shortages and regulatory requirements.
When to choose gel or water packs: Gel packs are best for chilled goods like dairy, produce and meal kits because they maintain the 2–8 °C range and are reusable. Water packs suit everyday use—keeping lunch boxes cool for a few hours—but expect condensation. Combining gel packs with dry ice can extend both the frozen and chilled zones inside a single cooler.
Innovative applications and trends in cold chain for 2025
The cold chain industry is evolving rapidly in response to changing consumer demands, regulatory pressures and sustainability goals. Here are the most important trends for 2025 and how they affect kitchen dry ice pack sheets.
Sustainability and green logistics
Environmental sustainability is now a requirement rather than an option. Cold chain operations, which are energy intensive, face increasing pressure to reduce their carbon footprint while maintaining efficiency. In 2025, innovations in green logistics include using renewable energy to power refrigerated fleets and facility operations, and optimizing routes to minimize fuel consumption. Dry ice production has environmental implications because CO₂ supply comes mainly from ethanol and ammonia plants; supply grows slower than demand, causing shortages and price volatility. Many manufacturers are investing in capturing CO₂ from bio ethanol plants or industrial exhausts to produce more sustainable dry ice.
Artificial intelligence and IoT monitoring
The adoption of AI powered route optimization Und IoT enabled cold chain monitoring is transforming how perishable goods are transported. Artificial intelligence adjusts delivery routes in real time based on traffic and weather conditions, reducing fuel consumption and ensuring on time deliveries. IoT sensors embedded in reusable containers and dry ice compartments track temperature, Luftfeuchtigkeit und Standort, sending alerts when deviations occur. These technologies allow suppliers to use the exact amount of dry ice needed, avoiding waste and extending product shelf life. This digital visibility is increasingly demanded by regulators and customers.
Leicht, smart shipping containers and sustainable materials
Innovations in container design are leading to lightweight, insulated shipping containers equipped with sensors that monitor conditions in real time. Some incorporate solar powered refrigeration units for off grid areas or use vacuum insulation panels (VIPs) and aerogel materials to improve efficiency. The trend towards sustainable packaging solutions includes using recyclable materials and reducing the environmental impact of cold chain logistics. Gel and hybrid packs that are reusable and leak free reduce waste compared with single use dry ice sheets. Bei Verwendung von Trockeneis, look for suppliers who capture CO₂ from sustainable sources and design sheets with recyclable outer films.
Growth of the cold chain market
International trade and organized retail are driving remarkable growth in the cold chain sector. According to a MarketsandMarkets report, the global cold chain market, geschätzt bei UNS $228.3 Milliarden in 2024, is projected to reach UNS $372.0 Milliarden von 2029 (CAGR 10.3 %). The expansion of e commerce and subscription food services requires reliable frozen and chilled shipping solutions. Dry ice sheets play a key role in these services because they enable cost effective last mile delivery of frozen products without investing in expensive active refrigeration. Jedoch, producers must adapt to supply fluctuations; dry ice consumption is growing about 5 % annually while CO₂ supply grows only 0.5 %, leading to periodic shortages.
Resilience and climate change
Climate change introduces new risks to cold chain operations. Extreme weather events—such as floods and droughts—disrupt transportation routes and refrigeration infrastructure. Companies are investing in built to suit cold storage facilities with resilient designs and backup power to withstand temperature fluctuations. Der Move to –15 °C initiative encourages industry partners to adopt energy efficient refrigeration technologies that operate at slightly warmer frozen temperatures (–15 °C instead of –18 °C) to reduce electricity consumption. While dry ice provides –78.5 °C, the initiative highlights the need to balance extreme cold with sustainable energy use.
Häufig gestellte Fragen
Frage 1: Can dry ice pack sheets be reused?
NEIN. Im Gegensatz zu Gelpackungen, dry ice sheets sublime completely and cannot be refrozen. You can extend their life by storing unused portions in an insulated cooler and using them within 2–3 days, but once the CO₂ is gone, the sheet no longer provides cooling.
