Dry Ice Bricks vs. Pack Sheets: Optimal Cold Chain Solutions in 2025

في صناعة اللوجستيات السلسلة الباردة, maintaining the required temperature for sensitive goods like pharmaceuticals, المأكولات البحرية, and meats is essential for ensuring product safety. Dry ice bricks and pack sheets are two effective cooling solutions widely used to achieve this. Understanding the differences between these options can help businesses select the right solution for their needs.

What Are Dry Ice Bricks and Pack Sheets?

Dry Ice Bricks
Dry ice bricks are solid blocks of carbon dioxide that sublimate at -78.5°C, providing a concentrated and long-lasting cooling source. These bricks are ideal for long-duration shipments, such as frozen foods or biological samples that require sustained, ultra-low temperatures.

Dry ice pack sheets are flexible panels filled with small pellets of dry ice. These are often used for shorter shipments or for packaging products that require chilled, rather than frozen, درجات الحرارة. Their flexibility allows them to conform to various package shapes, offering efficient cooling for goods such as cosmetics or pharmaceuticals.

How Do Dry Ice Bricks and Pack Sheets Perform in the Cold Chain?

Both dry ice bricks and pack sheets work by sublimating, a process where solid CO2 transitions directly to gas, absorbing heat and cooling the surrounding environment. The key differences between these forms lie in their cooling duration and flexibility.

ميزة	Dry Ice Bricks	صفائح حزمة الثلج الجافة
مدة التبريد	72–120 hours	24-48 ساعة
المرونة	جامد, less adaptable	مرن, conforms to shapes
Cooling Type	Ultra-frozen	مبردة (2درجة مئوية - 8 درجة مئوية)
Ideal Applications	Long-duration shipments	Short to medium-duration shipments

تطبيق العالم الحقيقي:
على سبيل المثال, vaccines requiring transport at ultra-low temperatures for up to 96 hours benefit from dry ice bricks, whereas fresh pharmaceuticals needing a controlled temperature range for up to 48 hours can be efficiently transported with dry ice pack sheets.

أفضل الممارسات لاستخدام الجليد الجاف في الشحن

التغليف المناسب & العزل
To optimize the performance of dry ice, use high-quality insulated packaging like Styrofoam or vacuum-insulated panels. Ensure containers are vented to allow CO2 gas to escape and prevent pressure buildup, which could damage the shipment.

How Much Dry Ice to Use?
لشحن 24 ساعة, استخدم تقريبًا 0.5 kg of dry ice per kg of product weight. For shipments lasting longer than 48 ساعات, increase the quantity of dry ice to account for the sublimation rate. لرحلات أطول, dry ice bricks are recommended due to their extended sublimation time.

Dry Ice Bricks vs. Pack Sheets: Which Is Best for Your Needs?

Dry Ice Bricks
Ideal for long shipments where products need to remain frozen for several days. They have higher upfront costs but offer longer-lasting cooling and higher capacity, making them essential for high-value, temperature-sensitive goods such as biologics or frozen food.

Best for short-haul deliveries or when products require a chilled environment. They are cost-effective and flexible, fitting well around smaller packages. لكن, they do not last as long as dry ice bricks, making them less suitable for long shipments.

Environmental Impact and Sustainability

As the cold chain logistics industry moves toward more sustainable practices, the production of dry ice from CO2 captured during industrial processes has gained traction. This practice reduces reliance on fossil fuels and lowers carbon footprints. بالإضافة إلى ذلك, innovations in packaging and monitoring technology are helping reduce waste and enhance the efficiency of dry ice use.

Sustainability Trends for 2025:

Eco-friendly packaging باستخدام المواد القابلة لإعادة التدوير وقابلة للتحلل الحيوي
Smart temperature sensors for real-time monitoring to reduce waste
Closed-loop dry ice recycling الأنظمة, allowing dry ice to be reused

الأسئلة المتداولة (التعليمات)

س 1: كم من الوقت يستمر الجليد الجاف أثناء الشحن?
عادة ما يستمر الجليد الجاف بين 24 ل 72 ساعات, depending on the form (bricks or sheets), العزل, and shipping conditions.

Q2: Is dry ice safe for shipping?
نعم, dry ice is safe for shipping when handled properly. Always use vented containers and follow safety guidelines to prevent CO2 buildup.

س 3: How do I calculate the amount of dry ice I need?
يستخدم 0.5 kg of dry ice per kg of product for a 24-hour shipment. لفترات أطول, increase the amount accordingly.
