Cara Menggunakan Paket Es Kering untuk Pengiriman Makanan (2025)

Diperbarui: Agustus 19, 2025
Anda ingin a Paket es kering untuk pengiriman makanan that keeps products safe, patuh, dan hemat biaya. Secara sederhana: use dry ice when you need ultracold, use hydrated “ice sheets” or PCM (perubahan fase) panels for chilled or −20 °C lanes, and right‑size the coolant by time and insulation. Real dry ice requires venting and UN1845 labels; hydrated/PCM packs do not.

What is a dry ice pack for shipping food—and when is it not real dry ice?

Jawaban singkat: Many “lapisan es kering” are hydrated polymer ice blankets or PCM panels Anda membekukan dan menggunakan kembali; mereka bukan co₂ solid. Real dry ice is carbon dioxide at −78.5 °C (−109,3°F) itu Sublimat ke gas, so packages must vent and carry UN1845 tanda. Use hydrated/PCM for chilled or −20 °C holds; use real dry ice for ultracold or long frozen runs.

Mengapa itu penting bagi Anda: Hydrated sheets and PCM are non‑hazmat and simplify training; real dry ice adds labeling, ventilasi, and booking details. Untuk keamanan pangan, hold refrigerated items at ≤40°F through delivery; use 0 °F for freezer targets.

Lapisan es kering vs. gel vs.. PCM vs.. es kering asli (mana yang harus kamu pilih?)

Hydrated “dry ice sheets” wrap products, membeku rata, and shine for 33–40°F memegang. Paket gel are simple and reusable for chilled lanes. Panel PCM (MISALNYA., ~5 °F or −20 °C) act like a “thermal battery,” bridging chilled↔frozen without hazmat. Es kering asli wins when “arrives rock‑solid frozen” is non‑negotiable or transit is 48–72 h+.

Pendingin	Typical Temp/Hold	Tanah air?	Apa artinya bagimu
Hydrated “ice sheets”	~10–32 °F for 24–48 h	TIDAK	Flexible wrap for meal kits and short parcel.
Paket gel	~20–32 °F for 24–48 h	TIDAK	Biaya rendah, easy handling for 2–8 °C lanes.
Panel PCM (≈5 °F/−20 °C)	Flat plateau at setpoint	TIDAK	Frozen‑assist or −20 °C holds without DG.
Es kering asli (Co₂)	−109,3°F / −78.5 ° C.	Ya	Best for ultracold/long frozen; lubang angin & Label UN1845.

Tips praktis yang bisa Anda terapkan hari ini

Kit makan (48 H): Line walls and top with hydrated sheets; add one 5 °F PCM brick against proteins for colder stability.
Makanan penutup beku: Tempat es kering di atas (udara dingin tenggelam) and add a thin sheet/PCM layer to protect surfaces; Ventilasi kotaknya.
Rute panas: Menambahkan 25–50% more sheet/gel mass or upgrade insulation (MISALNYA., kapal VIP).

Kasus nyata: A bakery replaced all‑dry‑ice loads with two PCM bricks + three hydrated sheets for chilled SKUs and held 34–38 °F over 36 h, eliminating DG surcharges. Frozen SKUs kept a small dry‑ice topper for “rock‑solid” arrivals.

How many dry ice packs for shipping food do you need per day?

Fast rules that work:

Es kering (CO₂ nyata): rencana ~5–10 pon per 24 jam per kotak terisolasi; increase for larger coolers, dinding tipis, atau panas.
Hydrated sheets/gel (dinginkan): tentang 1 lb per cubic foot per 24 h to hold 33–40 °F; add 25–50% for hot lanes.
Panel PCM: size by coverage and setpoint (MISALNYA., −20 ° C.); fully precondition per vendor guidance.

Starting points you can copy:

25pengirim ‑qt: ~10 lb dry ice for 24 h, atau 2–3 lembar + 1 bata PCM untuk dingin.
45pengirim ‑qt: 15–20 pon es kering for 24 h, atau 4–5 lembar + 2 batu bata PCM untuk dingin.

How to pack a dry ice pack for shipping food, langkah demi langkah?

Lakukan ini: hydrate or precondition → freeze solid → wrap → top‑load cold mass → seal (vent if using CO₂). Keep products pre‑chilled to ≤40 °F or pre‑frozen to 0 °F to prevent early temperature spikes.

Condition the coolant:
- Hydrated sheets: soak mesh side, drain, Dan freeze flat 24 h.
- PCM: freeze to labeled setpoint (MISALNYA., −20 ° C.) until fully solid.
Bungkus muatannya: line bottom and sides; mengisi semua kekosongan to stop warm air loops.
Tambahkan lapisan atas: cold mass on top; tutup ventilasi if using real dry ice.
Close and label: Tambahkan Data Logger, seal the shipper, apply marks if any CO₂ is used.

Do you really need gel/PCM instead of a dry ice pack for shipping food?

Jika spesifikasi Anda adalah 2–8 ° C. atau −20 ° C. within 24–48 h, gel atau PCM often hits the target with less handling and no hazmat. Untuk 48–72 h ultracold or “arrives rock‑solid,” es kering still rules. Many teams now run hibrida: PCM around the product plus a small dry‑ice topper for worst‑case heat.

Is a dry ice pack for shipping food allowed by 2025 operator?

Ya, with specifics:

Iata DGR ke-66 (2025): tanda “Es kering/karbon dioksida, padat", UN1845, Dan Berat bersih (kg); memastikan ventilasi kemasan; gunakan 2025 Daftar Periksa Penerimaan when dry ice is the only DG.
Catatan pembawa (2025): FedEx/UPS follow IATA internationally and domestic rules; check their job aids for label sizes and same‑face placement with Class 9.
USPS (air mail): ≤5lb per potong, wadah berventilasi, UN1845 on address side; surat internasional dengan es kering adalah dilarang.
Penerbangan penumpang: 2.5 kg (5.5 lb) per passenger per package, diperlukan persetujuan maskapai penerbangan, paket diberi ventilasi dan ditandai. Gel/PCM packs may fly in carry‑on if beku padat di pemutaran film.

2025 trends for the dry ice pack for shipping food

Apa yang baru tahun ini: lebih jelas Iata labeling and Net - kg booking practices, wider use of PCM at −20 °C to reduce hazmat touchpoints, and steady reminders to hold refrigerated foods at ≤40°F. Isolasi yang lebih baik (MISALNYA., kapal VIP) means less coolant mass on many lanes—good for cost and claims.

Sekilas

Penerimaan yang Didorong Daftar Periksa: fewer handoff surprises when UN1845 and net‑kg are correct.
Paket hibrida: PCM + sheets for chilled, dry‑ice topper for edge cases.
Workplace CO₂ awareness: 5,000 PPM TWA / 30,000 ppm STEL—ventilate staging areas.

Wawasan pasar: Upgrading insulation often saves more than adding coolant. Validate each lane with Data Loggers and lock the SOP once performance is proven.

FAQ: common questions about the dry ice pack for shipping food

Q1: Will a dry ice pack for shipping food keep items frozen for 2–3 days?
Sering Ya with real dry ice sized at 5–10lb/24h, great insulation, and tight packing. For −20 °C spec, PCM can replace some or all dry ice.

Q2: Are hydrated “dry ice sheets” the same as a dry ice pack for shipping food?
TIDAK. Hydrated sheets and PCM are bukan co₂; they freeze and do not vent gas. Real dry ice is CO₂ and needs venting/labels.

Q3: How much hydrated sheet or gel do I need with my dry ice pack for shipping food?
Mulai Dekat 1 lb per ft³ per day for chilled holds, then adjust after a pilot with a logger.

Q4: What temperatures should I target for safety when using a dry ice pack for shipping food?
Keep refrigerated foods at ≤40°F ujung ke ujung; keep frozen items at 0 ° f or below before packout.
