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.
Longa duração: 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:
| Método de resfriamento | Faixa de temperatura | Duração típica | Implicações Práticas |
| Manto de gelo seco (5 milímetros) | –78,5 °C a –18 °C | 24–36 h | Leve; best for local frozen deliveries. |
| Manto de gelo seco (10 milímetros) | –78,5 °C a –18 °C | 48–72 h | Balanced weight and cooling for medium haul meat shipments. |
| Manto de gelo seco (20 mm+) | –78,5 °C a –18 °C | 96 h+ | Ideal for international or high value meat shipments; highest cost and weight. |
| Pacotes de gel | 2 °C–8 °C | Até 48 h | Suitable for chilled meats but cannot maintain frozen conditions. |
| Materiais de mudança de fase (PCMs) | Personalizado (0 °C–10 °C) | Varia | Hold precise temperatures; good for fresh or partially frozen products. |
| Vacuum insulated panels with cold packs | –20 °C a 10 °C | 7–10 days | Premium long haul solution; expensive and non reusable. |
Exemplo prático
Caso: 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 horas. 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?
Durações de envio mais longas
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, não há água derretida, 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

Ao contrário dos pacotes de gel, dry ice sheets don’t require plastic pouches, Reduzindo resíduos de plástico. 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: Práticas recomendadas
Sizing Guidelines
Use the weight rule: Planeje 5–10 libras (2.27–4,54kg) de gelo seco por 24 hours of transit for meat. Para remessas com mais de 48 horas, match the dry ice weight to the product weight.
Choose sheet thickness: Select 5 milímetros sheets for local deliveries up to 36 horas, 10 milímetros for 48–72 hours and 20 mm+ para 96 horas ou mais.
Considere a sensibilidade do produto: Ultra cold items like cell therapies require thicker sheets, whereas frozen meat may only need 10 folhas mm.
Minimizar o espaço aéreo: Fill voids with crumpled paper or foam to slow sublimation and keep temperatures stable.
Packing Technique
Camada corretamente: 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.
Ventive o contêiner: Leave a small vent or use breathable polymer film to allow CO₂ gas to escape.
Pré-resfrie o recipiente: 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, peso, destino, 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 (por exemplo, –20 °C meat and –70 °C biologics).
Practical Scenario
Exemplo: 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
