Are Disposable Dry Ice Sheets Safe for Insulin Shipping?
إجابة قصيرة: Dry ice sheets are not inherently “FDA approved” and can freeze insulin if used alone. Dry ice is solid carbon dioxide at –78.5 °C, far colder than insulin’s 2 نطاق درجة مئوية – 8 درجة مئوية. To protect your medicine, you must place a buffer layer such as +5 °C phase change material (بي سي إم) bricks between the insulin and the dry ice sheet. Without this barrier the extreme cold can denature insulin proteins and make the medication unusable.
Why FDA compliance doesn’t mean what you think
When marketers describe a “FDA approved” dry ice sheet, they are referring to the materials that encase the dry ice—not the carbon dioxide itself. الولايات المتحدة. طعام & Drug Administration regulates packaging materials that touch food or drugs through its Food Contact Notification (FCN) عملية. Compliant dry ice sheets use foodsafe plastics like highdensity polyethylene (HDPE) أو polypropylene (ص), nontoxic refrigerant gels, and foodsafe adhesives. They must also display the UN1845 hazard label to warn handlers that carbon dioxide is inside. Even when all components are certified, the CO₂ will still remain at –78 °C, so you still need insulation and a buffer to protect your medicine.
Components of a FDA compliant dry ice sheet
FDA compliant dry ice sheets rely on several materials to ensure safety and performance. كل مكون يلعب دورا محددا:
| عنصر | مادة نموذجية | Food safety significance | ماذا يعني لك |
| الفيلم الخارجي | HDPE, البولي إثيلين المنخفض الكثافة أو PP | These inert plastics resist chemical migration and remain flexible at low temperatures. | Keeps your insulin container free from contamination and prevents film cracking during freezing and transport. |
| هلام التبريد | Foodgrade superabsorbent polymer | The gel freezes into a solid block without leaching chemicals. | Provides cooling without leaving messy water and can sometimes be reused for short trips. |
| المواد المانعة للتسرب & مواد لاصقة | مواد لاصقة تذوب بالحرارة آمنة للطعام | Create leakproof seals to keep CO₂ contained. | Prevents gel leaks and ensures the dry ice sheet doesn’t rupture during travel. |
| وضع العلامات | UN1845 hazard label | Required for DOT/IATA transport. | Informs carriers that your package contains dry ice and helps you comply with airline regulations. |
Practical tips when considering dry ice sheets
Request documentation: Always ask your supplier for FDA compliance certificates and hazard labels to verify that the films, gels and adhesives meet food contact standards.
Use a thermal buffer: Never let dry ice touch insulin directly. أ +5 °C PCM brick or medical gel pack must be between them.
التسمية بوضوح: Mark your package with “Contains Dry Ice / ثاني أكسيد الكربون, Solid” and list the net weight. Airlines require this information.
Assess insulation quality: When buying dry ice sheets, confirm that the film thickness matches your shipping duration and ambient temperature.
مثال الحالة: A remote clinic needed to send insulin to a rural location 48 hours away. They placed vials in a rigid case, wrapped them with +5 درجة مئوية من الطوب PCM, added insulation, and then positioned 0.8 كجم من الثلج الجاف في الحجرة الخارجية. A data logger recorded temperatures of 3.5 °C–6 °C for two days, proving that the buffer prevented freezing while the dry ice sheet supplied extra cooling.
How to Package Insulin with Disposable Dry Ice Sheets
Protecting insulin during transit requires a layered “thermal sandwich.” This technique separates the medicine from subzero refrigerants while still taking advantage of dry ice’s longlasting cold. اتبع هذه الخطوات:
Stepbystep packout instructions
Precondition your PCM or gel packs: برد +5 °C PCM bricks or medical gel packs in the refrigerator for at least 24 hours to stabilize them at 2 درجة مئوية -8 درجة مئوية. Do not freeze them; freezing could make them too cold and risk freezing the insulin.
تحضير الأنسولين: Place insulin vials or pens in a rigid plastic or metal case to prevent crushing and provide structure.
Create a thermal sandwich: Surround the insulin case with chilled PCM bricks on all sides, leaving a 1–2 cm gap between the medicine and any subzero element. This buffer ensures temperatures stay within the 2 نطاق درجة مئوية – 8 درجة مئوية.
أضف العزل: استخدام عزل عالي الجودة, مثل البوليسترين الموسع (EPS), موسع البولي بروبيلين (إي بي بي) أو ألواح معزولة بالفراغ (VIP), لإبطاء نقل الحرارة. Prechill the insulation if possible.
Position the dry ice sheet: Place the disposable dry ice sheet outside the PCM layer in the outer compartment of your cooler. Ensure there is space for CO₂ gas to escape; never seal the container airtight.
التسمية والتهوية: Mark your container with the dry ice hazard label and net weight, and create vents or leave the lid slightly ajar to let gas escape.
مراقبة درجة الحرارة: Insert a data logger near the insulin. ضبط التنبيهات على 2 درجة مئوية و 8 °C to ensure the packout stays within range. Testing the setup for 12–24 hours before your trip helps you finetune the arrangement.
Sizing your dry ice sheet: climate and duration
The amount of dry ice you need depends on the trip length, درجة الحرارة المحيطة وجودة العزل. Overpacking can freeze insulin, while underpacking risks overheating. Use these guidelines:
| Journey & مناخ | وزن الثلج الجاف الموصى به | معنى عملي |
| رحلة قصيرة (≥18 ساعة, ≥25 درجة مئوية) | 0 كجم من الجليد الجاف; اثنين +5 °C PCM bricks are sufficient | For day trips or mild climates, skip the dry ice. PCMs alone maintain 2 درجة مئوية -8 درجة مئوية. |
| رحلة معتدلة (25-32 درجة مئوية, 18-36 ساعة) | 0–0.5 kg of dry ice per day | أضف عزلًا إضافيًا وطوب PCM إضافي; only a small dry ice sheet if the ambient temperature is high. |
| مناخ حار (≥32 درجة مئوية) أو رحلة متعددة الأيام (>36 ساعات) | 0.5-0.8 كجم من الثلج الجاف يوميًا | Use a buffered dry ice packout: four or more PCM bricks plus a larger sheet of dry ice. Keep the dry ice outside the PCM layer. |
| General rule of thumb | 5– 10 رطل من الثلج الجاف (2.27-4.54 كجم) sublimate every 24 ساعات; ابدأ بـ أ 1:1 نسبة الوزن (وزن الثلج الجاف : وزن المنتج) للشحنات تصل إلى 48 ساعات, adjusting 25–50 % for summer or longer distances. | Use formulas like (حجم المبرد × الفجوة الحرارية × 0.12) ÷ 150 × 1.25 for large containers. |
Practical packout scenarios and advice
مسافة قصيرة (<18 ساعات): Pack insulin in a hard case with two chilled PCM bricks and insulation. Skip the dry ice completely.
24–48 hour trips: استخدم 1:1 ratio guideline: match the weight of your dry ice sheet to the weight of the insulin and PCM case, and add extra insulation.
Long distance shipments (48-72 ساعة): Combine dry ice sheets with highperformance insulation or a VIP cooler. Use multiple PCM bricks and 0.5–0.8 kg of dry ice per day.
أسئلة لتطرحها على نفسك: كم هي رحلتك? What’s the hottest expected temperature? How many vials or pens are you transporting? Will you have access to refrigeration at your destination? هل تسمح قواعد الطيران بالثلج الجاف على طريقك؟? Answering these helps determine whether you need dry ice and how much.
Label and trial run: Airlines limit passengers to 2.5 كجم (5.5 رطل) من الجليد الجاف, so weigh your sheet and mark the net weight. Conduct a test run at home to verify the packout before your actual trip.
سيناريو العالم الحقيقي: A home chef mailing a genetic testing kit across the country used a 500 g dry ice sheet with a 500 g sample in a prechilled box. She placed a cardboard layer between the dry ice and the specimen, labeled the package and kept the cooler vented. The sample arrived within 48 ساعات عند درجة الحرارة المناسبة.

Essential safety practices
ارتداء معدات الحماية: قفازات معزولة, long sleeves and eye protection are mandatory when handling dry ice. Use tongs or a scoop instead of your bare hands.
تهوية: Work in a wellventilated area and keep car windows open during transport. يطلق الثلج الجاف غاز ثاني أكسيد الكربون الذي يمكن أن يحل محل الأكسجين ويسبب الاختناق.
تجنب الحاويات محكمة الإغلاق: Never store dry ice in sealed coolers or glass jars. As the CO₂ sublimates it builds pressure and can cause explosions.
يُحفظ بعيدًا عن الأطفال والحيوانات الأليفة: Dry ice should only be handled by responsible adults.
شحنات التسمية: ألصق فئة 9 ملصق المخاطر ولاحظ الوزن الصافي للثلج الجاف. Provide safety instructions for the recipient.
الإسعافات الأولية: In the event of frostbite, immerse the affected area in warm (ليست ساخنة) water and seek medical attention.
Regulatory guidelines for 2025
Airline limits: Passengers may carry dry ice only with airline approval and must limit it to 2.5 كجم (5.5 رطل) per package or per passenger. Commercial cargo may allow up to 200 كجم, but carriers set their own limits. Always check your airline’s rules.
Ventilation and labeling: DOT and FAA regulations require packages containing dry ice to be vented and marked with “Dry ice” or “Carbon dioxide, صلب,” along with the net weight. The outermost container must carry a hazard class 9 label and the UN 1845 معرف.
التعبئة والتغليف الثلاثي: Pharmaceutical packaging standards often call for triple containment—a primary container (insulin vial), secondary rigid case and outer insulated package. Always ensure your dry ice sheet remains outside the secondary barrier.
CO₂ rate of loss: Expect 5–10 lb of dry ice to sublimate every 24 ساعات. Add extra for possible delays.
التوثيق: Carry a Material Safety Data Sheet (صحيفة بيانات سلامة المواد) for dry ice and verify your supplier’s certifications.
