What Is the Best Dry Ice Sheet for Meat and How Does It Work?
A dry ice sheet for meat shipping is a flexible sheet filled with compact carbon dioxide cells that absorb heat and turn directly into gas, keeping your cargo ultra cold without leaks. Each sheet combines three key elements: solid CO₂ cells, multi layer polymer film, and evenly spaced thermal cells. The CO₂ absorbs latent heat and sublimates into gas, maintaining temperatures between −78.5 °C and −18 °C for 48–96 hours. The polymer film controls gas release and prevents moisture exposure, while the thermal cell design distributes cold evenly across your shipment. Because there’s no meltwater, meat stays dry, packaging remains intact and bacterial growth is minimized.
Temperature Range and Performance of Dry Ice Sheets for Meat
Ultra cold range: Dry ice sheets maintain temperatures from −78.5 °C to −18 °C, ensuring that meat stays frozen during transit.
Long duration: Depending on thickness, a single sheet can provide 24–96 hours of cooling.
Consistent distribution: Evenly spaced cells distribute cold air, reducing “hot spots” that could thaw meat.
The following table compares dry ice sheets with other cooling options for meat shipping:
| Cooling Method | Temperature Range | Typical Duration | Practical Implications |
| Dry ice sheet (5 mm) | –78.5 °C to –18 °C | 24–36 h | Lightweight; best for local frozen deliveries. |
| Dry ice sheet (10 mm) | –78.5 °C to –18 °C | 48–72 h | Balanced weight and cooling for medium haul meat shipments. |
| Dry ice sheet (20 mm+) | –78.5 °C to –18 °C | 96 h+ | Ideal for international or high value meat shipments; highest cost and weight. |
| Gel packs | 2 °C–8 °C | Up to 48 h | Suitable for chilled meats but cannot maintain frozen conditions. |
| Phase change materials (PCMs) | Custom (0 °C–10 °C) | Varies | Hold precise temperatures; good for fresh or partially frozen products. |
| Vacuum insulated panels with cold packs | –20 °C to 10 °C | 7–10 days | Premium long haul solution; expensive and non reusable. |
Practical Example
Case: A seafood exporter uses dry ice sheets to deliver salmon across the country. By lining the cooler walls and placing a thinner sheet on top, they create a thermal “lid” that keeps fish below –18 °C for 72 hours. The exporter reduced spoilage by 37 % and used smaller boxes thanks to the sheet’s flexibility.
Benefits of Using Dry Ice Sheets for Meat Shipping: Why Are They the Best?
Longer Shipping Durations
Dry ice sheets provide consistent ultra low temperatures longer than gel or water packs, keeping meat frozen for up to 48–96 hours. This makes them essential for long distance or international shipments where travel times and temperature control are critical.
No Meltwater and Non Toxic Cooling
Because dry ice sublimates directly from a solid to a gas, there is no meltwater, preventing soggy packaging and preserving meat quality. Dry ice is also non toxic and leaves no residue.
Customizable and Flexible
The amount of dry ice used can be tailored to specific needs; thicker sheets extend duration, while thinner sheets reduce weight. Flexible sheets conform to irregular shapes and allow you to pack smaller boxes, reducing shipping costs and materials.
Reduced Spoilage and Cost Savings
Maintaining proper freezing reduces bacterial growth and spoilage, improving customer satisfaction. Fewer returns mean lower costs for shippers. Additionally, because dry ice doesn’t melt, there is no need for extra absorbent materials or waterproof liners, saving packaging costs.
Circular Economy and Reduced Plastic Waste
Unlike gel packs, dry ice sheets don’t require plastic pouches, reducing plastic waste. Many producers capture CO₂ from industrial byproducts, repurposing what would otherwise be greenhouse gas emissions.
How to Use and Size a Dry Ice Sheet for Meat: Best Practices
Sizing Guidelines
Use the weight rule: Plan on 5–10 pounds (2.27–4.54 kg) of dry ice per 24 hours of transit for meat. For shipments longer than 48 hours, match the dry ice weight to the product weight.
Choose sheet thickness: Select 5 mm sheets for local deliveries up to 36 hours, 10 mm for 48–72 hours and 20 mm+ for 96 hours or more.
Consider product sensitivity: Ultra cold items like cell therapies require thicker sheets, whereas frozen meat may only need 10 mm sheets.
Minimize air space: Fill voids with crumpled paper or foam to slow sublimation and keep temperatures stable.
Packing Technique
Layer correctly: Place a dry ice sheet at the bottom of the insulated container, add meat in sealed packaging, fill empty spaces with cushioning and place another sheet on top.
Separate products from dry ice: Use a cardboard or foam barrier between the sheet and the meat to prevent freezer burn.
Vent the container: Leave a small vent or use breathable polymer film to allow CO₂ gas to escape.
Pre chill the container: Chill the cooler or insulated box before loading to reduce initial heat load and extend cooling time.
Interactive Sizing Tool Recommendation
To simplify sizing, use an interactive Dry Ice Sheet Calculator that asks for product type, weight, destination, ambient temperature and transit duration. The tool calculates the optimum sheet thickness and quantity, ensuring you meet compliance without overpacking. It can also suggest layering strategies for mixed loads (e.g., –20 °C meat and –70 °C biologics).
Practical Scenario
Example: A butcher is shipping 10 kg of premium steaks overnight. Using the weight rule, he chooses a 10 mm dry ice sheet weighing 10 kg for a 48 hour buffer. He places the sheet at the bottom of a pre cooled box, lays vacuum sealed steaks on top, fills voids with paper and places another sheet on top. The meat arrives solidly frozen and undamaged.
Safety and Regulatory Considerations for Shipping Meat with Dry Ice Sheets
Hazard Classification and Weight Limits
Dry ice is classified as a Class 9 “miscellaneous” hazardous material by the International Air Transport Association (IATA) and the U.S. Department of Transportation (DOT). Packages must allow gas venting and be strong enough to withstand temperature changes. Air shipments are limited to 200 kg of dry ice per package, though individual passengers on commercial flights may carry up to 2.5 kg per person.
Safety Equipment and Handling
Personal protective equipment: Wear insulated gloves and goggles when handling dry ice sheets to avoid frostbite.
Ventilation: Use containers with vented lids or breathable film so CO₂ gas can escape.
Package integrity: Choose sturdy boxes and insulated containers; Styrofoam alone isn’t enough.
Labeling: Affix a Class 9 hazard label and write “Dry Ice, UN 1845” with the net weight on the package.
Documentation: Note “dry ice” on the air waybill for non-dangerous goods; include a Shipper’s Declaration when required.
Training: Hazmat employees must receive general awareness and function-specific training within 90 days of hiring and every two years for air shipping.
Home User Safety Tips
Wear gloves and eye protection when breaking or handling sheets.
Work in well ventilated areas; avoid confined spaces like car trunks.
Keep children and pets away from dry ice; use under adult supervision.
Avoid airtight storage; vent containers to prevent pressure build up.
Dispose of responsibly: Allow leftover dry ice to sublimate in a safe, ventilated area; never dispose of it down drains or trash chutes.
Regulatory Table
| Compliance Element | Requirement | Reason |
| Hazard label | Class 9 label with UN 1845 and net weight | Alerts handlers to CO₂ hazards. |
| Ventilation | Use vented lids or permeable film | Prevents pressure buildup and CO₂ buildup. |
| Weight limits | ≤200 kg per package (air); ≤5–10 lb per 24 h for small packages | Avoids excessive gas release; ensures safe handling. |
| Training | Hazmat training for employees within 90 days of hiring; refresher every two years | Ensures proper handling and documentation. |
| Documentation | Air waybill note and Shipper’s Declaration (if required) | Records compliance and informs carriers. |
Case: A local charcuterie failed to label a dry ice shipment properly. The airline refused the package, causing delays and spoilage. After adding the UN 1845 label and training their staff, the charcuterie shipped safely and avoided fines.
Sustainability and Environmental Impact
Dry ice sheets rely on carbon dioxide, a greenhouse gas that contributes to climate change. However, modern production methods often capture CO₂ from bioethanol fermentation or other industrial processes, repurposing waste gas instead of releasing it into the atmosphere. This circular approach reduces reliance on fossil fuels and lowers the carbon footprint of dry ice production.
Supply and Market Challenges
The dry ice market is growing rapidly. In 2024, it was valued at USD 1.54 billion and is projected to reach USD 2.73 billion by 2032, a compound annual growth rate of 7.4 %. Consumption has been rising at roughly 5 % per year, while CO₂ supply has grown only 0.5 % annually, leading to periodic shortages and price surges up to 300 %. Market stress is compounded by regulatory pressures and geopolitical issues affecting CO₂ production.
Bio Based CO₂ Sources
Bioethanol plants offer a promising solution: they capture CO₂ released during fermentation and convert it into food grade dry ice. This creates a lower carbon supply chain and demonstrates how renewable fuels and cold chain logistics can complement each other.
Sustainable Packaging and Hybrid Solutions
Recycled CO₂: Choose suppliers that source dry ice from captured industrial CO₂.
High performance insulation: Use vacuum insulated panels or recyclable box liners to reduce dry ice consumption.
Hybrid systems: Pair dry ice sheets with phase change materials or gel packs to extend duration and reduce the total CO₂ used.
Reusable polymer sheets: Some logistics dry ice sheets feature reinforced coatings for multiple uses; inspect and refill according to manufacturer guidelines.
Environmental Table
| Strategy | Environmental Benefit | How It Helps You |
| Recycled CO₂ production | Reduces fossil fuel emissions by using industrial waste gas. | Lowers your carbon footprint and aligns with sustainability goals. |

| Biodegradable insulation | Replaces EPS foam with compostable materials, reducing waste. | Improves brand reputation and supports eco conscious consumers. |
| Reusable polymer sheets | Allows multiple shipments; reduces waste and long term cost. | Saves money over repeated use and supports sustainability. |
Real world example: A meat subscription box company switched from single use foam coolers to recyclable vacuum insulated liners combined with dry ice sheets. By using recycled CO₂ and hybrid cooling, they cut packaging waste by 40 % and received positive feedback from customers who valued sustainability.
Alternatives to Dry Ice Sheets for Meat Shipping
While dry ice sheets offer exceptional ultra cold performance, they are not the only option. Depending on the distance, product type and budget, consider these alternatives:
Gel Packs – Best for Short to Mid Range Refrigerated Shipping
Gel packs keep temperatures below 40 °F (4.4 °C) for up to 48 hours, making them ideal for fresh cuts, cured meats or CSA boxes. They’re reusable and nontoxic but can’t keep meat fully frozen on long routes.
Phase Change Materials (PCMs) – Precise Temperature Control
PCMs absorb and release heat at specific temperatures. A PCM rated at 32 °F (0 °C) melts and solidifies at that point, keeping meat chilled without freezing. PCMs are more accurate than gel packs but cost more and often need specialized suppliers.
Refrigerated Trucks or Coolers with Ice Packs – Bulk Local Deliveries
For farmers markets or local restaurant deliveries, refrigerated trucks or coolers with ice packs offer a simple, hands on alternative. This method doesn’t require hazardous materials labels and is cost effective for short distances. However, it’s impractical for long routes where carriers lack cold storage.
Vacuum Insulated Panels (VIPs) with Cold Packs – Long Distance Frozen Shipping
VIPs slow down temperature change, keeping meat frozen for seven to ten days. They reduce the number of cold packs needed and can lower weight, but they’re expensive and typically single use.
Wool Insulation with Ice or Gel Packs – Eco Friendly Regional Shipping
Made from natural sheep’s wool, these liners are biodegradable and compostable. Paired with gel or ice packs, wool insulation maintains safe temperatures for one to two days. It’s perfect for farms or brands prioritizing sustainability.
Comparison Table of Dry Ice Alternatives
| Method | Ideal Use | Duration | Advantages | Disadvantages |
| Dry ice sheets | Long distance frozen meat shipping | 24–96 h | Ultra cold; no moisture; flexible | Hazardous material; requires handling and labeling |
| Gel packs | Short range chilled meat | Up to 48 h | Reusable; safe to handle | Not cold enough for frozen meats; may require extra insulation |
| PCMs | Mid range, precise temperature | Varies (32 °F, etc.) | Accurate; protects fresh or partially frozen products | Higher cost; specialized sourcing |
| VIPs with ice packs | Cross country or international shipments | 7–10 days | Long duration; reduces number of cold packs | Expensive; often single use |
| Wool insulation | Eco friendly regional deliveries | 1–2 days | Compostable; sustainable | Limited duration; needs extra packs |
Tips for Choosing Alternatives
Assess delivery range and temperature requirements. For fresh meats in local deliveries, gel packs or wool insulation may suffice. For long distance shipments, consider dry ice sheets or VIPs.
Evaluate cost versus sustainability. Wool insulation and PCMs are eco friendly but may cost more. Dry ice sheets provide performance but require hazard compliance.
Test before adopting. Use a probe thermometer to monitor internal temperatures during trial shipments.
Example: A farmer selling cured sausages at a weekend market uses gel packs and wool liners instead of dry ice. The products stay below 40 °F for 36 hours, avoiding the hassle of hazardous labeling and meeting consumer expectations for eco friendly packaging.
