What Are Disposable Dry Ice Pack Sheets?
Disposable dry ice pack sheets are thin, flexible layers made from solid carbon dioxide (الثلج الجاف) encased in polymer sheets. They sublimate from solid to gas at -78.5°C, providing cold without moisture, unlike traditional ice packs. Their ability to maintain consistent sub-zero temperatures makes them ideal for long-duration shipments.
How Do They Work?
Dry ice sublimates directly into gas, absorbing heat from its surroundings and keeping your products cool. With a typical duration of 24-72 ساعات, depending on sheet thickness and insulation, dry ice sheets maintain temperature integrity across long distances.
| طريقة التبريد | مدة نموذجية | رُطُوبَة | الأفضل ل |
|---|---|---|---|
| Dry Ice Pack Sheet | 24-72 ساعات | لا أحد (subledlimates) | اللقاحات, أغذية مجمدة, البيولوجيا |
| حزمة هلام | 6-12 ساعات | Water when melted | Refrigerated items |
| حزمة الجليد | Shorter durations | Water when melted | Day trips, picnic coolers |
Why Choose Disposable Dry Ice Pack Sheets?
كفاءة تبريد فائقة
Dry ice pack sheets provide higher cooling capacities than gel packs and traditional ice. Their ability to maintain ultra-cold temperatures for up to 72 hours or more makes them perfect for sensitive shipments, including pharmaceuticals and biologics.
Leak-Free & ينظف
على عكس الجليد, الذي يذوب في الماء, dry ice sublimates without leaving moisture, ensuring your goods remain dry and safe from water damage.
Cost-Effective for Long-Distance Shipping
Although the initial cost may seem higher, dry ice pack sheets prove cost-effective due to their extended cooling duration and reduced need for bulky insulation. Their lightweight design also cuts down on shipping costs by reducing dimensional weight.
التطبيقات عبر الصناعات
-
طعام & المشروبات: Dry ice pack sheets keep frozen foods, اللحوم, المأكولات البحرية, and baked goods at the right temperature during transit, منع التلف.
-
الأدوية & التكنولوجيا الحيوية: Maintaining strict temperature control is crucial in shipping vaccines, البيولوجيا, and other sensitive medical products.
-
التجارة الإلكترونية & Meal Delivery: With the rise of frozen meal kits, dry ice pack sheets are vital for ensuring safe and timely delivery without compromising the product’s quality.
How to Use Disposable Dry Ice Pack Sheets
Step-by-Step Activation
-
Hydrate the Sheet: Immerse the dry ice pack sheet in warm water to hydrate the polymer cells. Massage the cells until fully expanded.
-
تجميد: Place the sheet in a freezer for at least 24 ساعات, ensuring it reaches the lowest possible temperature for optimal performance.
-
Pack the Sheet: بعد التجميد, place the sheet inside your cooler with the fabric side facing the product. Ensure proper venting to allow CO₂ gas to escape.
Practical Tips for Use
-
Pre-chill Your Products: Freezing or chilling your goods before packing helps reduce the heat load and extends the cooling duration.
-
Use Larger Sheets for Longer Durations: Larger sheets contain more CO₂, resulting in longer-lasting cooling effects.
Comparing Dry Ice Sheets with Other Cooling Methods
| طريقة التبريد | مدة نموذجية | رُطُوبَة | الأفضل ل |
|---|---|---|---|
| Dry Ice Pack Sheet | 24-72 ساعات | لا أحد (subledlimates) | اللقاحات, أغذية مجمدة, البيولوجيا |
