Dry Ice Pack for Fish: How to Ship Frozen Right

A dry ice pack for fish keeps seafood deeply frozen through parcel and air lanes when sized, packed, and labeled correctly. Rencana 5–10 lb per 24 jam, position dry ice on top so cold air falls, and keep packages vented for CO₂. Target ≤32°F (0° C.) for chilled Dan ≤−18°C for frozen arrivals to cut spoilage and claims. That approach ships frozen right.

How much dry ice pack for fish do you need for 24–72 hours?

Jawaban singkat: size a dry ice pack for fish at 5–10 lb per 24 hours in a quality shipper, then add 20–50% safety for summer or multi-hub routes. Full boxes and thicker insulation slow sublimation and extend hold time.

Mengapa itu berhasil: Dry ice is −78.5°C and sublimates (no liquid), creating a cold reservoir that protects frozen fish for long transits. The more surface area exposed and the warmer the route, the faster it disappears—so pack tight and upgrade insulation before simply doubling pounds. Use a data logger to verify.

Dry ice pack for fish sizing calculator (quick start)

# Inputs: payload_lb, hours_in_transit, box_efficiency (1.0 premium; 1.2 average; 1.5 poor)
base_rate = 0.25 # lb dry ice per lb payload per day (frozen fish)
days = max(1, hours_in_transit/24)
recommended = payload_lb * base_rate * days * box_efficiency
# Round up to nearest 5 lb, then +25% for hot lanes. Place dry ice on top.
Route & Box Baseline (lb/24h) Add-On Buffer Apa artinya bagimu
Semalam, premium shipper 5–7 +0–25% Fewer pounds if box is full and pre-chilled
48 jam, average EPS 10–15 +25–40% Split across top and side pieces to avoid hot spots
72 jam, hot lane 15–25 +40–50% Consider VIP liners or PCM hybrid to cut total dry ice

Pro tip: Tempatkan dry ice pack for fish above product so the “cold dome” falls over fillets; keep a paper or corrugate spacer to prevent freezer burn.


How do you pack a dry ice pack for fish safely?

Use a “box-in-box” method: liner and spacer, tight-packed fish, es kering di atas, vented outer, and UN1845 labels. Keep packages non-airtight so CO₂ can escape; never tape all seams shut.

Step-by-step pack-out

  1. Pre-freeze product and pre-chill the shipper.

  2. Add a spacer so fish sit above condensate.

  3. Load vacuum-sealed fish; fill voids to reach 80–95% box fill.

  4. Tempatkan dry ice pack for fish di atas, wrapped in paper; add side PCM if superchilling.

  5. Close the inner liner, leave designed vent paths, and label UN1845 with net dry-ice weight.

  6. Insert a USB/BLE data logger to document time-at-temperature.

Box-in-box checklist (avoid the usual failure modes)

Variabel Better Setting Worse Setting Apa artinya bagimu
Isolasi ≥2″ rigid PU or high-R liner ≤1″ EPS Hours more hold time
Mengisi % 80–95% full Half-empty Sublimasi yang lebih lambat
Penanganan Minimal door opens Frequent opens Protects the cold pool
Carrier path Direct/overnight Multi-hub/day+ Add 25–50% ice margin

Dry ice pack for fish vs. gel/PCM: which should you pick?

If delivery must be frozen, choose a dry ice pack for fish; for superchilled 0 to −2°C fish, use −21°C PCM and add a small dry-ice topper only for risky lanes.

Cooling method Rentang temp Terbaik untuk Trade-offs Your move
Dry ice pack for fish ~ −109 ° F. (−78.5 ° C.) Frozen deliveries, 24-72H Hazmat labels; vents required Use when “frozen-solid on arrival” is non-negotiable
PCM −21°C bricks −6 to −21°C setpoints Superchilled quality Higher upfront cost Hybrid with small dry-ice topper
Paket gel (2–8 ° C.) Item dingin Mixed baskets, live seafood Cannot keep items frozen Keep sauces/side items from freezing

What rules and labels apply to a dry ice pack for fish?

Lubang angin, label, dan menyatakan. Dry ice is UN1845 (Kelas 9 untuk udara). Passenger flights often cap packages at 2.5 kg (5.5 lb); cargo services allow higher but require “Carbon dioxide, solid/Dry Ice,” UN1845, Dan net dry-ice weight pada paket.

2025 trends shaping your dry ice pack for fish strategy

Apa yang baru: Paper-based liners, low-cost BLE loggers, and reusable PCM cartridges are mainstream. Many shippers now meet SLA with fewer pounds of dry ice pack for fish, validated with logger proof.

At-a-glance advances

  • Paper liners: 48–72h performance with recyclability

  • Pemantauan yang lebih cerdas: BLE/NFC loggers cut claims

  • Sensor freshness: Biosensors for fish quality grading
