What Makes Mini Dry Ice Ice Packs Superior to Traditional Ice or Gel Packs?
Mini dry ice ice packs differ from ordinary ice because they reach significantly lower temperatures and avoid melting. Traditional gel or water ice packs freeze at around 0 ° C., which suits chilled goods but fails when items require deep freeze conditions. Sebaliknya, mini dry ice packs operate between –78.5 °C and –18 °C and maintain that range for 24–48 hours. Their sublimation process means they turn directly from solid to gas, leaving no liquid residue and preventing damage to sensitive products like electronics or biological samples.
Key advantage: Mini dry ice ice packs offer a dramatic performance leap over conventional ice. They hold temperatures for nearly twice as long and eliminate moisture, making them ideal for ultra low temperature shipments.
Understanding Sublimation and Energy Capacity
Sublimation is the direct transition from solid to gas. When mini dry ice packs sublimate, they absorb large amounts of heat, maintaining a constant cold environment. This contrasts with gel packs, which absorb heat slowly and leave behind water.
Below is a comparison of energy capacity and performance:
| Metode pendinginan | Kisaran suhu | Lamanya | Manfaat |
| Mini dry ice ice pack | –78,5 °C hingga –18 °C | 24–48 h | Longest cooling duration; tidak ada kelembaban; suitable for pharmaceuticals and frozen meals |
| Traditional ice or gel pack | 0 ° C. | 12–24 h | Durasi yang lebih pendek; moisture risk; suitable only for chilled goods |
| Paket PCM (–21 °C or other) | –21 °C atau 2–8 °C | 24–72 jam | Good for intermediate temperatures; dapat digunakan kembali; tidak berbahaya |
Mini dry ice packs have a higher latent heat of sublimation than water (571 kJ/kg versus 334 kJ/kg for ice), which means they can absorb almost twice the heat before dissipating. Their low density also allows them to fit more efficiently within packaging, minimizing dead space and reducing dimensional weight charges—a crucial cost factor in air freight.
Why Mini Dry Ice Packs Benefit Ultra Cold Shipments
Mini dry ice packs keep payloads below –18 °C for 24–48 hours, making them indispensable when shipping vaccines, Biologi, frozen diagnostics, and certain food items. Misalnya, A 250 g mini dry ice pack can maintain a 750 ml biologic kit below –60 °C for roughly 52 jam, outperforming traditional pellets by 38 %. This extended hold time helps companies reduce recharging stops and ensures compliance with tight temperature tolerance requirements.
How Do You Size and Use Mini Dry Ice Ice Packs Safely and Efficiently?
Determining the right amount of mini dry ice is critical. Too little, and your shipment risks thawing; too much, and you increase cost and weight needlessly. Several formulas and rules of thumb can guide your calculations.
Sizing Formula Based on Payload and Ambient Temperature
One common approach estimates the required dry ice mass using the formula below:
DryIce(kg) = Muatan(kg) × 0.35 + (Lingkungan Δ°C ÷ 10) × 0.1 × Muatan(kg)
This equation suggests that for each kilogram of payload, kamu perlu kira-kira 0.35 kg of mini dry ice. The second term adjusts for ambient temperature differences; untuk setiap 10 °C above freezing, menambahkan 0.1 kg es kering per kilogram muatan.
Contoh: If you are shipping a 5 kg payload with an expected ambient difference of 20 ° C., the required mass would be:
DryIce(kg) = 5 × 0.35 + (20 ÷ 10) × 0.1 × 5 = 1.75 + 1.0 = 2.75 kg
For safety, round up and consider environmental factors like insulation quality or transit time.
Rule of Thumb for 24 , 48 and 72 Hour Trips
Menurut panduan industri, plan for 2.3–4.5 kg (5–10 lb.) of mini dry ice per 24 jam untuk setiap 5 kg of payload. Untuk durasi yang lebih lama, multiply by factors: 1.2 for hot ground conditions or 1.3–1.4 for air freight due to lower pressure and higher heat influx. A cheat sheet from Tempk suggests baseline amounts:
| Lamanya & Kondisi | Typical Ambient | Mini Dry Ice Required | Catatan |
| 24 H (mild conditions) | 15–20 °C | 1.5–2,0kg | Use quality insulation |
| 48 H (tanah campuran) | 20–30 °C | 3.5–5,0kg | Surround Payload; menghilangkan ruang kepala |
| 72 H (panas, terisolasi vakum) | >30 ° C. | 6.0–7.5 kg | VIP insulation reduces needs by 10 % |
These estimates can be adapted for mini dry ice ice packs, which provide the same sublimation energy but in a more compact form. Always test under realistic conditions before full deployment.
Proses Pengepakan Langkah demi Langkah
Proper packing ensures maximum efficiency and safety. Ikuti langkah-langkah ini:
Kondisikan terlebih dahulu pengirimnya: Sebelum memuat, pre cool your insulated box for 15–30 minutes with a starter charge of mini dry ice to quickly pull down the internal temperature.
