عبوات ثلج جافة الحجم XL are available across gel and rigid “brick” formats, and case counts are predictable by size. باختصار: 32 oz usually ship 18 per case, 48 oz ship 12 per case, و 64 oz vary 4–10 per case depending on brand and film/foam style. You’ll also see 60 oz foam bricks at about 6 per case. This guide shows you how to choose, سفينة, and right-size purchases for 2025.

What counts as XL-size dry ice packs, and which size should you choose?
Answer in brief: XL-size dry ice packs typically mean 32–64 oz refrigerant packs in flexible gel or rigid brick styles. 32 أوز fits narrow shippers; 48 أوز is the common “large” workhorse; 64 أوز delivers fewer touches and longer holds but has wider case-count swings. حزم الثلج الجاف here refer to gel/PCM coolants, not solid CO₂.
لماذا هذا يهم لك: Larger packs cut picks and fill voids with fewer touchpoints. If you need 0–8 °C or moderate frozen holds, gel XL often avoids hazmat headaches. If you must keep ≤−20 °C for long durations, consider real dry ice with PI 954 وضع العلامات, or −21 °C PCM bricks when you want non-hazmat deep-frozen control. Always validate against your hottest lane profile.
كم عدد XL-size dry ice packs per case by size?
Most teams standardize procurement using a simple map:
-
32 أوز (هلام): 18/case
-
48 أوز (هلام): 12/case
-
64 أوز (هلام): 4, 8, or 10/case (brand/film dependent)
-
60 oz foam brick (جامد): ~6/case
-
44 oz rigid brick: 18/case
-
56 oz rigid brick: 12/case
| مقاس & أسلوب (XL) | Typical Case Count | Common Dimensions (in.) | ماذا يعني لك |
|---|---|---|---|
| 32 oz gel | 18 / case | ~10.5 × 5.5 × 1.25 | Narrow footprint; easy to stack; good for 24–48 h lanes. |
| 48 oz gel | 12 / case | ~10.5 × 7.5 × 1.25–1.5 | The “standard large”; balanced mass and placement flexibility. |
| 64 oz gel | 4-10 / case | ~11 × 8 × 1.5–2 | Fewer touches; verify brand-specific counts before ordering. |
| 60 oz foam brick | ~6 / case | ~9 × 8 × 1.5 | Rigid shape; resists compression under tight collars. |
| 44 oz rigid brick | 18 / case | ~8 × 8 × 1.75 | Stackable geometry; good for return/reuse programs. |
| 56 oz rigid brick | 12 / case | ~10.5 × 8 × 1.75 | High mass for 48–72 h frozen with robust insulation. |

-
Frozen D2C, 24-36 ساعة: يستخدم واحد 64 أوز أو اثنين 48 أوز for similar mass; يختار 48 oz if placement flexibility is vital.
-
Hot summer lanes (>35 درجة مئوية), 48 ح: ابدأ مع اثنين 64 أوز أو three 48 أوز and validate with data loggers.
-
2–8 °C biologics, 48 ح: One 48 أوز + one 24–32 oz often smooths swings better than a single large pack.
حالة حقيقية: A frozen-food sender replaced four 16 أوز packs with اثنين 32 oz XL packs and cut packout time by ~25% while passing a 48-hour summer profile. The bigger units reduced leaks and improved temperature stability.
كم عدد XL-size dry ice packs do you need per shipment?
إجابة مباشرة: Match pack mass to payload mass, insulation R-value, lane duration, and ambient swings. As a fast field rule, يضيف واحد 48 أوز for every 12–18 hours of extra exposure beyond a working baseline, then confirm with a chamber test or a lane pilot.
From your perspective: If you’re replacing many small packs, XL-size dry ice packs lower labor and reduce voids. For longer lanes or higher ambient heat, تصعيد ل 64 oz or add one more 48 أوز. Always precondition packs fully and instrument a few shipments to measure worst-case dwell and sortation delays.
Quick sizing checklist for XL-size dry ice packs
-
درجة الحرارة الهدف: CRT (15-25 درجة مئوية), Chill (2-8 درجة مئوية), or Frozen (≤−10 °C)?
-
Transit hours: Door-to-door plus 20% slack for delays.
-
العزل: EPS/VIP/paper liner; thicker walls reduce pack mass.
-
حمولة: High-water foods have “free cooling”; low-moisture payloads warm faster.
-
Season & خط: استخدم summer profile unless you have proven lane data.
XL-size dry ice packs مقابل. real dry ice and −21 °C PCM: which fits your lane?
Core guidance:
-
يستخدم الثلج الجاف الحقيقي (UN1845) for ultra-low targets or long, الممرات الساخنة. علامة "الجليد الجاف/ثاني أكسيد الكربون, صلب,” add net dry-ice mass (كجم), استخدم فصل 9 ملصق, and keep packaging تنفيس (ها هو بي 954, 2025).
-
يختار −21 °C PCM bricks عندما تحتاج non-hazmat frozen control (≤ - 18 درجة مئوية) for 24–72 h with simpler ops.
-
يختار XL-size dry ice packs (0 °C gel) ل 2-8 درجة مئوية and short frozen holds without hazmat handling.
| سائل التبريد | الحالة التنظيمية | Typical large-case counts | الوجبات السريعة الخاصة بك |
|---|---|---|---|
| الثلج الجاف الحقيقي (−78.5 درجة مئوية) | Dangerous goods; ها هو بي 954; vented pack required | Sold by weight | Maximum frozen margin; add labeling and training. |
| −21 °C PCM bricks | Not DG | 12-24 / case (large) | Deep-frozen control without hazmat paperwork. |
| 0 °C gel (XL-size dry ice packs) | Not DG | 12–18 / case (32–48 oz) | Easiest for 2–8 °C and moderate frozen holds. |

الأسئلة المتداولة
Do you offer larger or XL-size dry ice packs? How many per case?
نعم. XL typically means 32–64 oz. يتوقع 18/case at 32 أوز, 12/case at 48 أوز, و 4–10/case at 64 أوز depending on format.
Are “dry ice packs” the same as real dry ice?
لا. Many “dry ice packs” are gel or PCM coolants (non-hazmat). Real dry ice is CO₂ الصلبة and regulated for air shipments.
What labels do I need in 2025 if I use real dry ice?
علامة UN1845, أضف net dry-ice mass (كجم), apply the فصل 9 ملصق, وضمان تغليف التهوية لكل باي 954.
How many XL-size dry ice packs should I put in one box?
Start points: 1 × 64 أوز for 24–36 h frozen; 2 × 48 أوز for longer or hotter lanes. Validate with a lane pilot.
Can I fly with dry ice in baggage?
Passengers are limited to 2.5 كجم (5.5 رطل) per person with airline approval and vented packaging. Cargo uses PI 954.
ملخص & التوصيات
