What gear do you need to pack fish in dry ice?

Short list: pengirim terisolasi (≥1–2″ walls), rigid outer box, food‑safe vacuum bags, absorbent pad, vapor barrier liner, es kering (blocks or large pellets), isi kosong, sarung tangan terisolasi, Dan “Dry Ice/UN1845 + net kg” marks on the outside.

Mengapa itu berhasil: thick foam or VIP panels slow heat gain; vacuum bags block odors and freezer burn; the liner stops moisture from softening the carton; ventilasi prevents CO₂ pressure buildup. Start fish fully frozen, or fresh fish at ~32°F (0° C.). These small choices keep temperatures stable and reduce claims.

Es kering vs.. gel packs—when to use each for seafood?

Intinya: untuk how to pack fish in dry ice on multi‑day, jalur beku, use dry ice as the primary coolant. Gel packs are great as mendukung (smoother warm‑up curve) or for chilled‑not‑frozen pengiriman. If you must keep fish unfrozen, buffer the dry ice with cardboard and use less.

Jenis Paket	Dry Ice per 24h	Durasi khas	Apa artinya bagimu
EPS foam 1–1.5″	8–12 pon	24–48 h	Budget friendly; add buffer in summer.
EPS foam 2″	6–10 lb.	48–72 jam	Good for weekends if pre‑chilled.
Panel VIP	4–8 lb	72 jam+	Premi; best for hot routes or long customs.

Tips praktis yang bisa Anda terapkan hari ini

Pra -belukar segalanya: ikan, pengirim, dan isi kosong.
Atas + lapisan bawah: put some dry ice under and more on top; CO₂ dingin tenggelam.
Hindari segel kedap udara: meninggalkan jalur ventilasi; never shrink‑wrap the lid.
Write net kg: regulators expect kilograms on the label.

Kasus dunia nyata: 20 lb of salmon in a 2″ foam shipper with 18 pon es kering (belah atas/bawah) arrived after ~40 hours at −12 °C by data logger—no thaw and no leakage.

How much dry ice do you need to pack fish in dry ice selama 24-72 jam?

Aturan praktis: 5–10 lb per 24 jam, lalu tambahkan a hari penyangga untuk penundaan. Use the higher end for pellets, isolasi tipis, bukaan yang sering, or hot weather.

Why this range works: sublimation depends on surface area, isolasi, dan panas lingkungan. Thicker foam or VIP slows loss; minimizing voids reduces convection. Planning with a baseline plus buffer keeps loads frozen even when routes slip.
