Bantalan es kering: Bagaimana memilih, Ukuran & Kapal masuk 2025

Jika Anda mengirimkan barang yang mudah rusak, dry ice pads can keep food safe or frozen when used correctly—and compliant labeling matters when real dry ice (co₂ solid) is involved. Start with simple rules: rencana 5–10 lb es kering per 24 jam for deep-frozen lanes and keep chilled foods ≤40°F (4° C.) end-to-end. For passenger travel, dry ice is limited to 2.5 kg per paket. Diperbarui: Agustus 18, 2025.

Pick the right dry ice pads type for chilled vs. jalur beku (ekor panjang: dry ice pads for shipping food).

Menggunakan PCM pads and gel packs to skip hazmat when deep-freeze isn’t required.

What are dry ice pads—and which type do you need?

Jawaban singkat: Dry ice pads can mean two things. Insulated dry ice pads are fabric covers used with real dry ice to slow sublimation. Reusable “dry-ice‑style pads” are polymer/PCM sheets you hydrate or freeze; they are bukan CO₂ and suit chilled or moderate frozen ranges. Use real dry ice for ultracold (−78.5 ° C.) and use pads/PCM for 2–8°C or −10°C to −20°C targets.

Mengapa itu penting: Real dry ice requires vented packaging and UN1845 tanda; reusable pads/PCM don’t release gas and avoid hazmat paperwork, making handoffs simpler for many food lanes.

When should you choose PCM “dry ice pads” vs. es kering asli?

Untuk −20°C frozen but not ultracold: pick PCM pads (MISALNYA., 5°F/−15°C setpoints) to stabilize loads without CO₂ handling. Untuk ultracold or hard-frozen (es krim, long-haul meats), memilih es kering asli and vent the shipper. Either way, pre-chill products and fill voids to slow heat gain.

Pad / Refrigerant Type	What it is	Typical Temp Band	Apa artinya bagimu
Insulated dry ice pad (cover)	Fabric/insulated topper used dengan es kering	Works with −78.5°C	Reduces sublimation during frequent access; not a coolant by itself.
Hydrated “dry-ice‑style” pad sheet	Polymer cells you wet/freeze	~10–32°F (−12–0°C)	Great for 2–8°C chilled; mudah, non‑hazmat; flexible fit.
PCM panel (~5°F/−15°C)	Fixed‑setpoint phase‑change pack	~5–20°F (−15–−6°C)	Bridges chilled–frozen gap; more stable than gel; no CO₂ gas.
Es kering (Co₂, UN1845)	Solid carbon dioxide	−78.5 ° C. (−109.3 ° F.)	Best for ultracold; requires venting + pelabelan; plan mass carefully.

Tip Praktis untuk Anda

Akses yang sering? Add an insulated dry ice pad over dry ice between picks to slow loss.
Chilled lanes (≤40°F): Menggunakan dry ice pads (sheets/gel) and pack tight; add a 5°F PCM if ambient is hot.
Beku (−20°C) without hazmat: Menggunakan PCM pads around the payload for a flat cold plateau.

Kasus nyata: A cheesecake brand compared six “dry‑ice‑style” pads + two PCM panels vs. 12 lb dry ice in a 30‑qt shipper over 30 jam. Pads/PCM held 34–38°F with zero leaks; dry ice kept rock‑solid frozen—ideal for hard‑frozen SKUs.

How many dry ice pads—or pounds of dry ice—do you need?

Planning rules you can trust: Untuk dinginkan jalur, Mulailah dengan ≈1 lb of pad/gel per cubic foot per 24 H; scale up 25–50% for hot routes or thin insulation. Untuk deep‑frozen, rencana 5–10 lb es kering per 24 H per well‑insulated box. Validate with a small test and a logger before you scale.

Quick estimator (Salin/Tempel):

Container Size	Dry ice pads untuk 24 H (dinginkan)	Es kering untuk 24 H (beku)	Apa artinya ini bagi Anda
25‑qt shipper	2–3 hydrated pad sheets + 1 PCM panel	~10–15 lb	Pads hit 33–40°F; use dry ice for hard‑frozen outcomes.
45‑qt shipper	4–5 pad sheets + 2 Panel PCM	~15–20 lb	Layer top & bottom for uniform temps.
60‑qt shipper	6 pad sheets + 2–3 PCM panels	~18–25 lb	Fill voids and pre‑chill cargo to slow heat gain.

Field‑tested sizing cues

Hot route or long transit? Menambahkan 25–50% coolant and consider PCM to smooth swings.
Benchmark: A 25‑qt cooler typically needs ~10–15 lb/day of dry ice for frozen results.

How to pack with dry ice pads (and with dry ice) for safe delivery?

Chilled with pads/PCM/gel (tidak ada hazmat):
Pra -chill product ≤40°F; line bottom with pads; flank with PCM on the sides; top with gel; Isi kekosongan; fully segel (no vent needed for pads/gel).

Frozen with dry ice (tanah air):
Bekukan padat, tempat es kering di atas (wastafel dingin), vent package, Dan tanda: “Es kering” atau “karbon dioksida, padat,” UN1845, net dry‑ice weight (kg), plus Kelas 9 label. Ikuti 2025 Daftar Periksa Penerimaan.

Pelabelan & 2025 compliance made simple (UN1845)

Ventilasi: Never airtight—allow CO₂ to escape to avoid rupture.
Marks: Nama pengiriman yang tepat, UN1845, Kg net, pengirim/penerima, Kelas 9 berlian.
Air travel: 2.5 kg dry ice per passenger package, airline approval required.
Postal/Express: USPS air ≤5 lb; FedEx/UPS mirror IATA/49 CFR for packaging & tanda.

Pro tips that prevent warm arrivals

Prasyarat: Freeze PCM/gel 24–36 h; pre‑chill boxes.
Penempatan: Es kering di atas; pembalut dasar + atas; Minimalkan headspace.
Validasi: Drop a mini temperature logger in pilot boxes; standardize SOPs by lane.

Case in one line: With six pad sheets + two PCM panels, a 30‑hour lane held 34–38°F and avoided DG fees, while the same box with 12 lb dry ice arrived frozen solid. Choose per SKU and promise.

2025 trends in dry ice pads & cold chain—what changed?

Foto: Itu 2025 IATA DGR (66ed.) and carrier checklists formalize UN1845 weight/marking clarity; PCM adoption grows as brands seek non‑DG stability for −20°C runs; VIP liners and better insulation reduce required coolant mass. Expect hybrid packs: PCM dry ice pads around the payload, dengan a smaller dry‑ice topper for margin.

Kemajuan terbaru sekilas

Checklist clarity: Fewer acceptance rejections when UN1845 and net kg are on the same panel.
−20°C PCM maturity: More vendors, better hold times, simpler reconditioning.
CO₂ supply dynamics: Mixed strategies hedge price/availability risk with PCM hybrids.

Wawasan pasar: As insulation improves (MISALNYA., VIP liners), you’ll often ship the same payload with fewer pads or less dry ice, trimming freight and DG fees without sacrificing temperature.

Pertanyaan yang sering diajukan

1) Are dry ice pads the same as dry ice?
TIDAK. Insulated pads cover real dry ice to slow loss; reusable “dry‑ice‑style” pads are gel/PCM and suit chilled/moderate frozen—bukan ultracold −78.5°C.

2) Berapa banyak es kering per hari yang harus saya rencanakan?
Mulailah dengan 5–10 lb per 24 H in a quality shipper; add 20–30% for summer lanes; verify with a test.

3) Do PCM “dry ice pads” need hazmat labels?
TIDAK. PCM pads don’t release CO₂ gas and don’t require Class 9 labels—still validate duration.

4) Bisakah saya terbang dengan es kering?
Yes—up to 2.5 kg per passenger package in a ventilasi container with airline approval and proper marks.

5) What food safety target should I follow for chilled shipments?
Keep foods ≤40°F (4° C.) from packout through delivery; log pilot runs to confirm.
