XL-Size Dry Ice Packs 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, ship, 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 h: يستخدم one 64 أوز أو two 48 أوز for similar mass; pick 48 oz if placement flexibility is vital.
-
Hot summer lanes (>35 درجة مئوية), 48 ح: ابدأ مع two 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 two 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 one 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, step up to 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
-
Target temp: 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 & lane: 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 real dry ice (UN1845) for ultra-low targets or long, الممرات الساخنة. Mark “Dry Ice/Carbon dioxide, 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 when you need non-hazmat frozen control (≤ - 18 درجة مئوية) for 24–72 h with simpler ops.
-
Pick XL-size dry ice packs (0 °C gel) ل 2-8 درجة مئوية and short frozen holds without hazmat handling.
| سائل التبريد | Regulatory status | 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. |

2025 الاتجاهات تشكيل XL-size dry ice packs
ما الجديد هذا العام: Air carriers refreshed dry-ice acceptance checklists; gel and −21 °C PCM options keep expanding for simpler ops. More senders validate to seasonal profiles to trim over-icing and reduce chargeable weight. Paper-based liners and returnable systems change coolant mass needs and case-buy planning. تحديث passenger baggage rules still cap dry ice at 2.5 كجم per traveler; commercial cargo follows PI 954.

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, add the net dry-ice mass (كجم), apply the فصل 9 ملصق, and ensure تغليف التهوية لكل باي 954.

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.
