What Are Disposable Dry Ice Pack Sheets?
Disposable dry ice pack sheets are thin, flexible layers made from solid carbon dioxide (gelo seco) encased in polymer sheets. They sublimate from solid to gas at -78.5°C, providing cold without moisture, ao contrário das bolsas de gelo tradicionais. Their ability to maintain consistent sub-zero temperatures makes them ideal for long-duration shipments.
Como eles funcionam?
O gelo seco sublima diretamente em gás, absorbing heat from its surroundings and keeping your products cool. With a typical duration of 24-72 horas, depending on sheet thickness and insulation, dry ice sheets maintain temperature integrity across long distances.
| Método de resfriamento | Duração típica | Umidade | Melhor para |
|---|---|---|---|
| Folha de gelo seco | 24-72 horas | Nenhum (Sublelimates) | Vacinas, Alimentos congelados, Biologics |
| Pacote de gel | 6-12 horas | Water when melted | Itens refrigerados |
| Pacote de gelo | Shorter durations | Water when melted | Viagens de um dia, picnic coolers |
Why Choose Disposable Dry Ice Pack Sheets?
Eficiência de resfriamento superior
Dry ice pack sheets provide higher cooling capacities than gel packs and traditional ice. Their ability to maintain ultra-cold temperatures for up to 72 hours or more makes them perfect for sensitive shipments, including pharmaceuticals and biologics.
Leak-Free & Limpar
Ao contrário do gelo, que derrete na água, dry ice sublimates without leaving moisture, ensuring your goods remain dry and safe from water damage.
Econômico para remessas de longa distância
Although the initial cost may seem higher, dry ice pack sheets prove cost-effective due to their extended cooling duration and reduced need for bulky insulation. Their lightweight design also cuts down on shipping costs by reducing dimensional weight.
Aplicações entre indústrias
-
Comida & Bebida: Dry ice pack sheets keep frozen foods, carnes, frutos do mar, and baked goods at the right temperature during transit, evitando a deterioração.
-
Produtos farmacêuticos & Biotech: Maintaining strict temperature control is crucial in shipping vaccines, Biologics, and other sensitive medical products.
-
Comércio eletrônico & Entrega de refeições: With the rise of frozen meal kits, dry ice pack sheets are vital for ensuring safe and timely delivery without compromising the product’s quality.
How to Use Disposable Dry Ice Pack Sheets
Step-by-Step Activation
-
Hydrate the Sheet: Immerse the dry ice pack sheet in warm water to hydrate the polymer cells. Massage the cells until fully expanded.
-
Congelar: Place the sheet in a freezer for at least 24 horas, ensuring it reaches the lowest possible temperature for optimal performance.
-
Pack the Sheet: Depois de congelar, place the sheet inside your cooler with the fabric side facing the product. Ensure proper venting to allow CO₂ gas to escape.
Practical Tips for Use
-
Pre-chill Your Products: Freezing or chilling your goods before packing helps reduce the heat load and extends the cooling duration.
-
Use Larger Sheets for Longer Durations: Larger sheets contain more CO₂, resulting in longer-lasting cooling effects.
Comparing Dry Ice Sheets with Other Cooling Methods
| Método de resfriamento | Duração típica | Umidade | Melhor para |
|---|---|---|---|
| Folha de gelo seco | 24-72 horas | Nenhum (Sublelimates) | Vacinas, Alimentos congelados, Biologics |
| Pacote de gel | 6-12 horas | Water when melted | Itens refrigerados |
| Pacote de gelo | Shorter durations | Water when melted | Viagens de um dia, picnic coolers |
Mantos de gelo seco vs.. Pacotes de gel
Dry ice sheets provide colder temperatures, a longer cooling duration, e não deixe umidade, making them ideal for high-value, Produtos sensíveis à temperatura. Pacotes de gel, while effective, have shorter cooling durations and often leave behind water residue.
