أ حزمة الثلج الجاف للأسماك keeps seafood deeply frozen through parcel and air lanes when sized, معبأة, والمسمى بشكل صحيح. يخطط 5-10 رطل لكل 24 ساعات, position dry ice on top so cold air falls, and keep packages vented for CO₂. هدف ≤32°F (0درجة مئوية) لبرودة و ≤−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?
إجابة قصيرة: 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.
لماذا يعمل: Dry ice is −78.5°C and sublimates (لا سائل), 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 (بداية سريعة)
| طريق & صندوق | خط الأساس (رطل/24 ساعة) | Add-On Buffer | ماذا يعني لك |
|---|---|---|---|
| بين عشية وضحاها, premium shipper | 5-7 | +0-25 ٪ | Fewer pounds if box is full and pre-chilled |
| 48 ساعات, average EPS | 10-15 | +25-40 ٪ | Split across top and side pieces to avoid hot spots |
| 72 ساعات, حارة ساخنة | 15-25 | +40-50 ٪ | Consider VIP liners or PCM hybrid to cut total dry ice |
للنصيحة: ضع حزمة الثلج الجاف للأسماك 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, الجليد الجاف في الأعلى, تنفيس الخارجي, and UN1845 labels. Keep packages non-airtight so CO₂ can escape; never tape all seams shut.
Step-by-step pack-out
-
Pre-freeze product and pre-chill the shipper.
-
Add a spacer so fish sit above condensate.
-
Load vacuum-sealed fish; fill voids to reach 80–95% box fill.
-
ضع حزمة الثلج الجاف للأسماك في الأعلى, wrapped in paper; add side PCM if superchilling.
-
أغلق البطانة الداخلية, leave designed vent paths, and label UN1845 with net dry-ice weight.
-
Insert a USB/BLE data logger to document time-at-temperature.

| عامل | Better Setting | Worse Setting | ماذا يعني لك |
|---|---|---|---|
| العزل | ≥2″ rigid PU or high-R liner | ≤1″ EPS | Hours more hold time |
| يملأ % | 80–95% full | Half-empty | أبطأ التسامي |
| التعامل | 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. هلام/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.
| طريقة التبريد | نطاق درجة الحرارة | الأفضل ل | Trade-offs | تحركك |
|---|---|---|---|---|
| Dry ice pack for fish | ~ −109 ° f (−78.5 درجة مئوية) | الولادات المجمدة, 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 | تكلفة أولية أعلى | Hybrid with small dry-ice topper |
| حزم هلام (2-8 درجة مئوية) | العناصر المبردة | سلات مختلطة, المأكولات البحرية الحية | Cannot keep items frozen | Keep sauces/side items from freezing |
What rules and labels apply to a dry ice pack for fish?
تنفيس, ملصق, وتعلن. Dry ice is UN1845 (فصل 9 للهواء). Passenger flights often cap packages at 2.5 كجم (5.5 رطل); cargo services allow higher but require “Carbon dioxide, solid/Dry Ice," UN1845, و net dry-ice weight على الحزمة.
