You’ve likely seen people talk about dry ice foam or pack sheets, but what does that actually mean for your business? Simply put, dry ice foam and dry ice pack sheets are specialty refrigerants designed to keep sensitive products ultra cold without the mess of melting water. They rely on solid carbon dioxide (Co₂) that sublimates from solid to gas at –78.5 °C (–109.3 °F), absorbing heat and keeping your products frozen. The solid CO₂ pellets or blocks are sealed inside flexible foam or sheet materials, making them easier to handle than loose dry ice pellets. Dalam panduan ini, you’ll learn how dry ice foam and pack sheets work, how to choose the right option for different shipments, and why paying attention to 2025 trends can save you money and improve sustainability.

What Are Dry Ice Foam and Dry Ice Pack Sheets?
Dry ice foam and pack sheets are sealed pouches filled with solid CO₂ pellets or blocks that sublimate at –78.5 °C (–109.3 °F). Unlike gel packs that freeze around 0 °C and slowly melt, dry ice goes straight from solid to gas, releasing no liquid. That means your parcels stay moisture free and there’s no risk of soggy packaging or water damage. Es tradisional meleleh di 0 °C and typically lasts only 12–24 hours, making it suitable only for short journeys or products that need simple refrigeration. Sebaliknya, mini dry ice sheets maintain –78.5 °C to –18 °C for 24–48 hours, while larger pack sheets or disposable dry ice packs can last up to 72 hours with proper insulation.
Dry ice foam uses a flexible foam matrix to hold dry ice pellets. The foam adds a layer of insulation, spreading the cold evenly across your product and reducing point contact freezing. Dry ice pack sheets are thin, pliable pouches that can be wrapped around items like vaccines or meat to create uniform cooling. Both options are designed to be quick to activate: you simply take them out of the freezer (or fill them with dry ice pellets if using re fillable versions), pack them with your goods and place them in an insulated container.
Why Choose Dry Ice Foam Over Loose Pellets?
Using loose dry ice pellets is like sprinkling ice cubes into your shipment — it works but can be messy. Dry ice foam encapsulates pellets within a foam structure so they’re less likely to shift or settle during transit. This ensures consistent contact and helps maintain temperature for the full shipping duration. Foam also reduces sublimation rate by providing more surface area for heat absorption, which extends the life of the dry ice. For high value shipments that require ultra low temperatures, dry ice foam provides the reliability of dry ice with the ease of handling found in gel packs. Lebih-lebih lagi, the foam can be customized into various shapes to fit odd sized products.
| Teknologi Pendinginan | Kisaran suhu | Durasi khas | Manfaat praktis |
| Mini dry ice foam sheet | –78.5 °C to –18 °C | 24–48 h | Ideal for pharmaceuticals or biologics requiring consistent ultra low temperatures; no moisture risk |
| Disposable dry ice pack | –78,5 °C | Hingga 72 H | Perfect for long distance shipping of frozen meat, seafood or vaccines |
| Paket gel | 2 °C–8 °C | Hingga 48 H | Keeps produce, dairy or medicines cool without freezing; reusable but may leak |
Tips Praktis
Use foam sheets for delicate items: If you’re shipping vials or small components, the foam provides cushioning and uniform cold distribution.
Opt for pack sheets for longer transit: Disposable pack sheets typically hold more dry ice and last longer, making them suitable for cross country or international shipments.
Combine with insulation: Always pair dry ice foam or pack sheets with a well insulated container; adding a reflective liner can extend performance by up to 20 %.
Contoh kasus: A biotech firm shipping mRNA vaccines must maintain –70 °C for at least 48 jam. Using mini dry ice foam sheets inside vacuum insulated shippers, they preserved vaccine potency during a 36 hour flight and final mile delivery.
How Do Dry Ice Foam and Pack Sheets Work?
The science is simple: dry ice absorbs heat as it sublimates. Instead of melting like water based ice, es kering (co₂ solid) transitions directly into gas. At atmospheric pressure, this occurs at –78.5 °C. Because there’s no liquid stage, the cooling remains dry, preventing moisture damage. The foam or sheet encasing the dry ice slows the sublimation rate by reducing exposure to warm air, similar to how a thermos keeps beverages hot. As the CO₂ gas escapes, it displaces oxygen in the container, which helps keep microorganisms from growing but also necessitates proper ventilation.
Sublimation Explained in Everyday Terms
Imagine leaving ice cubes on your kitchen counter. They melt into a puddle, then eventually evaporate. Dry ice skips the puddle phase — it’s like watching snow vanish into thin air. During sublimation, the dry ice pulls heat from its surroundings, making the environment colder. This property is what keeps shipments at temperatures that traditional ice or gel packs can’t reach. Namun, because CO₂ gas is heavier than air, it can accumulate and pose asphyxiation risks in sealed spaces. That’s why storage containers must include ventsco2meter.com.
Key Components of a Dry Ice Pack Sheet System
CO₂ Pellets or Blocks: The core refrigerant material that holds the ultra cold temperature.
Foam or Sheet Material: A flexible matrix that holds the dry ice and slows sublimation.
Penghalang kelembaban: An outer film that prevents condensation or leaks, keeping your packages dry.
Insulated Container: Boxes or liners made of EPP, VIP or foam that minimize external heat transfer.
Ventilation Channels: Small holes or breathable membranes that allow CO₂ gas to escape safely.
By understanding each component, you can tailor your packout to ensure the best performance for your specific goods.
How to Use Dry Ice Foam and Pack Sheets for Shipping
Determine your cooling requirements. A simple starting point is the 1:1 aturan: for every kilogram of product weight, allocate roughly one kilogram of dry ice, adjusting for ambient temperature and insulation quality. This provides enough cooling for 24 jam. For longer routes, increase the ratio or add additional layers of insulation.
Step by Step Use Guide
Identify product requirements: Sensitive items like vaccines or frozen seafood require strict temperature ranges. Consider regulatory guidelines, MISALNYA., some biologics must be kept below –70 °C.
Calculate dry ice quantity: Gunakan 1:1 ratio as a baseline and adjust for variables (musim, destination climate and transit time). Untuk a 24 kg shipment in summer, you might need 30 kg of dry ice foam or pack sheets.
Select the right format: Choose mini foam sheets for pharmaceuticals or small shipments; pick larger pack sheets for bulk items or longer duration shipments.
Layer properly: Place dry ice foam or pack sheets above or around your products. A top placement cools from above, while surrounding placement provides even cooling. Hybrid configurations combine both for maximum duration.
Seal and insulate: Use high quality insulated boxes or liners. Tape seams to prevent warm air ingress. Add reflective foil or corrugated inserts to improve insulation.
Suhu monitor: Use data loggers or IoT sensors to track temperature throughout transit. Alerts allow you to intervene if there’s a deviation.
Menangani dengan hati -hati: Wear insulated gloves and safety goggles. Use tongs rather than bare hands to place the dry ice foam or pack sheetsco2meter.com.
Real World Application

| Terbaik untuk | Farmasi, Biologi, makanan gourmet | Bulk frozen meat, hidangan laut, cross country shipping | Menghasilkan, susu, short distance shipments |
Ringkasan: Dry ice foam is ideal for sensitive pharmaceuticals or perishable foods needing –78.5 °C to –18 °C for up to 48 jam. Pack sheets last longer, making them suitable for extended shipping or international deliveries. Gel packs offer milder temperatures and are better suited for chilled, tidak beku, goods.
How Much Dry Ice Foam or Pack Sheet Do You Need?
Calculate based on weight, transit time and insulation quality. A heavier payload or longer transit requires more dry ice. The general rule of thumb — 1:1 dry ice to product weight for 24 hours — is a starting point. Here’s a quick calculation tool (you can implement this as an interactive widget on your website to improve user engagement):
Enter product weight (kg): MISALNYA., 10 kg.
Enter desired transit time (jam): MISALNYA., 48 jam.
Select insulation quality: Tinggi (vacuum insulated), Sedang (busa), Rendah (basic cardboard).
Calculate dry ice required: Multiply the weight by the number of 24 hour segments (48 h = 2 segments) and add 10–20 % more if shipping in summer or through hot regions.
For our example, A 10 kg payload for a 48 hour trip with medium insulation needs roughly 10 kg × 2 = 20 kg of dry ice foam. Menambahkan 15 % for summer, total 23 kg. If using pack sheets rated for 72 jam, you could reduce quantity slightly.
Factors that Affect Quantity
Suhu sekitar: Hot climates accelerate sublimation. For summer shipments add 10–20 % lebih banyak es kering.
Insulation type: Vacuum insulated panels (VIP) require less dry ice than standard foam due to their superior thermal resistance.
Shipping mode: Air freight has lower temperature fluctuations than ground transport, but may involve longer transit times.
Product thermal mass: Frozen meat absorbs more heat than a small vial of vaccine, so heavier products need more dry ice.
