Kantong dryicepack: Cara mengirimkan barang beku dengan aman?
A dry ice pack bag locks cargo at −20 °C without pellets spilling everywhere—if you match bag weight to product mass and follow the latest IATA 954 and USPS 9A rules. Tes Lapangan menunjukkan tas 1lb menyimpan udang beku 5lb selama 32 jam, Namun 35% pengirim masih berlebihan dan membayar barang tambahan. Mari kita akhiri itu.

Gunakan 0,30lbbag dryicepack per pon produk beku untuk setiap kaki 48 jam. Angka itu berasal 2024 Uji bersepeda EPS -box yang ditiru 20 ° C - 35 ° C Tarmac Swings. Tingkatkan menjadi 0,40lb di pertengahan musim panas atau untuk styrofoam di bawah 1 inci.
| Berat produk (lb) | Waktu transit (H) | Berat tas (lb) | Suhu inti yang diharapkan (° C.) | Mengapa itu berhasil |
|---|---|---|---|---|
| 6 (Pint Gelato) | 24 | 1.0 | ≤−25 | Udara semalam |
| 12 (king crab) | 48 | 3.6 | ≤−22 | 2‑hari hari |
| 25 (cell therapy) | 72 | 10.0 | ≤−20 | Buffer akhir pekan |
The science: Dry ice sublimates 6‑8 % per day inside a vented bag. Matching weight to heat load avoids costly overfill while ensuring –18 °C compliance.
Apa 2025 Rules Govern Every Dry Ice Pack Bag?
Angkutan udara: IATA DGR 66th ed. limits each package to 200 kg and requires a Class 9 diamond plus net‑weight marking—now mandatory on the luar mengemas, bukan hanya tasnya.
Surat & small‑parcel: USPS Packaging Instruction 9A caps dry ice at 5 lb (2.27 kg) per air‑mail piece; international mail bans it outright.
Passenger luggage: Airlines allow 2.5 kg (5.5 lb) per traveler with prior approval—bag must vent CO₂.
Daftar Periksa Kepatuhan Cepat
-
Print “UN 1845” & weight in kg on bag or label sleeve.
-
Add at least one 6 mm vent hole or leave the zipper 2 mm ajar.
-
Remove old haz‑mat placards; mixed labels trigger inspections.
Failure means fines up to US $10 000 or cargo hold delays.
Which Bag Construction Delivers the Longest Chill?
Isi mikropelet + vapor‑permeable bio‑PE film + RF‑weld seams beats legacy block‑bags by 10‑12 hours. Baru 2025 models embed QR batch codes that log CO₂ loss once scanned.
| Fitur | Keuntungan Waktu Tahan | Manfaat Anda |
|---|---|---|
| Inti mikropellet | +10 H | Faster surface cooling |
| Jahitan RF ganda | Tingkat kebocoran < 0,3% | Survives cabin pressure swings |
| Bio‑PE film (ASTM D6400) | +5 H | Dapat dibuat kompos, lighter freight |
| Aerogel slip‑sleeve | +15 H | Shave 2 lb of coolant mass |
Industrial review data confirm bio‑PE liners cut total plastic 18 % and meet food‑contact safety.
Hands‑On Tips
-
Top‑load the bag: Udara dingin tenggelam; placing the bag on top wraps everything in chill.
-
Pre‑chill shipper at −10 °C—adds ~15 % hold‑time.
-
Fill voids with kraft cushions; empty air accelerates sublimation.
Kasus nyata: A Nevada seafood exporter swapped pellets for 3 lb dry ice pack bags and aerogel sleeves—refunds for partial thaw dropped 21 % across 4,000 pesanan.
Bag vs. Kotak: When Does Each Make Sense?
| Skenario | Kantong dryicepack | Pelet longgar | Membawa pergi |
|---|---|---|---|
| DTC frozen desserts | ✅ Cleaner unboxing | Berantakan | Bags win |
| Bulk palletized meat | ➖ | ✅ Cheaper per lb | Pellets win |
| Sampel klinis | ✅ Precise weight | ➖ | Bags meet SOPs |
