What Exactly Is a Dry Ice Pack vs Dry Ice?
Intro: A dry ice pack is not always the same as dry ice. In shipping and cold-chain work, a dry ice pack can mean a polymer-based PCM sheet you hydrate and freeze, or a pouch that actually contains solid CO₂. Knowing which one you have helps you hit the right temperature, avoid hazards, and stay compliant in 2025. This article merges and improves the three drafts you provided.

2025 tren: reusable −21 °C PCM, hybrid pack‑outs, and greener materials
What is a dry ice pack and why does the term confuse buyers?
Jawaban singkat: A dry ice pack is not always solid CO₂; it’s often a reusable phase‑change pack designed for set‑point cooling near 0 °C or −21 °C. Some vendors also use “dry ice pack” to describe packaged dry ice. That’s why you’ll see the same phrase on two very different products.
Plain‑English breakdown: If your pack recharges in a freezer and is reusable, you’re holding a PCM sheet or plate—no CO₂ inside. If your pack vents gas and requires gloves and labels, it’s true dry ice (co₂ solid). This distinction matters when you need chilled (2–8 ° C.), beku (≈−20 °C), or ultra‑cold (≈−78 °C) pertunjukan.
Bagaimana cara kerja paket es kering (PCM sheet) compared with dry ice?
PCM “dry ice pack”: A flexible sheet with super‑absorbent polymer cells that you soak, membekukan, dan menggunakan kembali. It freezes like water, holds a steady set‑point (often around −21 °C or 0 °C), and releases no gas.
Es kering (co₂ solid): Carbon dioxide frozen at about −78.5 °C. It skips the liquid phase and turns straight into gas (sublimasi), so packages must vent. It delivers very deep cold for long durations but carries frostbite and CO₂ exposure risks.
| Atribut | Paket es kering (PCM) | Es kering (Co₂ solid) | Apa artinya bagimu |
|---|---|---|---|
| Core material | Hydrated polymer/PCM | Frozen CO₂ | Pick based on whether you need reusable set‑point cooling or ultra‑cold power |
| Suhu kerja | ~0 °C or ~−21 °C | ~ −78.5 ° C. | Protect chill/frozen goods vs. keep items rock‑solid frozen |
| Perubahan Fase | Freezes/melts | Sublimates (Solid → Gas) | No gas vs. CO₂ gas requiring venting |
| Status Hazmat | Generally non‑hazmat | Dan 1845, Kelas 9 | Simplified shipping vs. pelabelan, pelatihan, ventilasi |
| Penggunaan kembali | Reusable hundreds of cycles | Consumed in transit | Lower waste and steady OPEX vs. one‑time use |
| Penggunaan khas | Menghasilkan, 2–8 °C pharma, D2C frozen meals | Es krim, deep‑frozen seafood, ultra‑cold biologics | Match your lane and product tolerance |
Practical tips you can apply today
-
If the label lists a set‑point (MISALNYA., −21 ° C.), it’s a dry ice pack (PCM), bukan co₂.
-
If it mentions UN 1845 or “vent packaging,” you’re dealing with dry ice.
-
Pre‑chill product, pendingin, and shipper. This reduces load and extends hold time.
-
Untuk makanan beku, wrap the payload with a Paket es kering on all sides for uniform contact.
-
For dry ice, always allow gas to escape; never shrink‑wrap or seal it in an airtight liner.
Contoh dunia nyata: A meal‑kit brand replaced two gel bricks with two −21 °C Paket es kering sheets and improved void fill. Warm‑arrival complaints fell in peak summer while freeze damage remained flat.
When should you choose a dry ice pack vs true dry ice?
Aturan praktis: Use a dry ice pack for refrigerated and standard frozen lanes; use dry ice for ultra‑cold lanes or when you need CO₂ atmosphere. This balances product quality, compliance burden, and cost.
Mengapa itu berhasil: A Paket es kering delivers controlled cold near its set‑point, preventing over‑freezing of produce and biologics. Dry ice provides extreme cold and long buffers but triggers hazmat rules and demands ventilation and PPE.
A quick decision framework (check all that apply)
-
Your lowest allowable product temp is ≥ −30 °C → choose a Paket es kering (−21 ° C.).
-
You need ≤ −40 °C for days → choose es kering.
-
You want reusable, non‑hazmat cooling → choose a Paket es kering.
-
You benefit from CO₂ atmosphere in‑box → choose es kering.
-
You ship by air with hazmat limits → prefer a Paket es kering.
| Skenario | Rentang target | Best choice | Mengapa | Watch -outs |
|---|---|---|---|---|
| Menghasilkan & 2–8 °C pharma | +2 °C to +8 °C | Paket es kering (0 °C or +5 °C) | Gentle, pendinginan yang stabil | Pre‑condition packs and shipper |
| D2C frozen desserts (24–48H) | −25 °C to −10 °C | Paket es kering (−21 ° C.) | Reusable and non‑hazmat | 360° wrap to avoid hotspots |
| Deep‑frozen biologics/seafood | ≤ −40 °C | Es kering | Ultra‑cold buffer | Ventilasi, APD, UN 1845 labeling |
| Long lanes with delays | −30 °C to −10 °C | Hibrida: Paket es kering + small dry ice | Extends hold without over‑freezing | Extra weight; hazmat rules apply |

2025 dry ice pack and cold‑chain trends that matter
Apa yang baru 2025: Dapat digunakan kembali Paket es kering sistem (especially −21 °C plates) are replacing one‑way gel in frozen food lanes. Hybrid pack‑outs (PCM + a small dry‑ice charge) help cover delays without over‑freezing sensitive items. Research into biodegradable “jelly ice” and better insulation (Panel VIP) reduces waste while improving hold time.

Wawasan pasar: Frozen D2C continues to expand, while pharma tightens compliance. Expect stricter carrier enforcement on dry‑ice declarations and broader adoption of non‑hazmat PCM for routine frozen and refrigerated lanes.
Dry ice pack FAQs (and dry ice basics)
Is a dry ice pack the same as dry ice?
TIDAK. A Paket es kering is usually a reusable PCM pack set around 0 °C or −21 °C; dry ice is solid CO₂ at ≈ −78.5 °C.
How long does a dry ice pack stay cold?
Plan for 24–36 h per box with good insulation and full 360° contact; add sheets or better insulation for longer lanes.
Can I fly with a dry ice pack?
Generally yes—it is not UN 1845. Jika Anda menambahkan es kering, follow airline limits and vent the package.
When should I avoid dry ice?
Avoid it with freeze‑sensitive goods and in poorly ventilated spaces. Gunakan a Paket es kering for controlled chill or standard frozen.
What’s the safest way to handle dry ice?
Wear gloves and eye protection, and ensure ventilation. Never seal dry ice in a rigid airtight container.
Ringkasan dan Langkah Selanjutnya
Kunci takeaways: Pilih A Paket es kering for steady, reusable cooling in chilled and standard frozen lanes; memilih es kering for ultra‑cold or multi‑day frozen shipments. Size refrigerant by your lane and insulation—not guesswork. Hybrid pack‑outs can bridge gaps when delays occur.
Rencana aksi: Map each SKU to an allowable temperature band, select the lightest‑hazard refrigerant that meets it, validate with data loggers in both summer and winter, and standardize SOPs by lane length.
