شرح موسع
Dry ice sheets act like mini cold batteries. The dry ice inside sublimates directly from solid to gas, absorbing considerable heat. One pound of dry ice produces 8.3 cu ft of CO₂ gas; this means your packaging must allow gas to vent to prevent pressure build up. Compared with traditional gel packs that melt and release water, a dry ice sheet leaves no liquid residue, keeping products dry. The outer film can be made from ورق, السليلوز أو البوليمرات القابلة للتحلل, which decompose naturally. Because dry ice sublimates into a gas, there is no water consumption and no solid waste.
في الخدمات اللوجستية لسلسلة التبريد, these sheets excel for shipments requiring درجات حرارة شديدة البرودة (-20 درجة مئوية إلى -70 درجة مئوية). Unlike traditional dry ice pellets that may require hazardous material documentation, flexible sheets are often classified as غير خطرة, تبسيط الامتثال. They activate immediately when flexed and provide consistent cold without the messy sublimation issues of loose dry ice. Combined with insulated containers and vented packaging, they maintain product integrity for overnight deliveries or long haul transport.

Safety Guidelines and Handling Tips
الثلج الجاف بارد للغاية, so treat it with respect. According to OSHA safety guidelines, dry ice is frozen carbon dioxide that does not melt into a liquid but changes directly into gas. The temperature of dry ice is -78 درجة مئوية, so touching it bare handed can cause frostbite. دائما ارتداء protective gloves and goggles.
Storage matters: keep dry ice in a حاوية معزولة بشكل جيد, لكن never in an airtight vessel because sublimation will cause the container to rupture. تخزينه في منطقة جيدة التهوية, not in a sealed room or vehicle; CO₂ gas is heavier than air and will displace oxygen. When transported inside a car, ensure fresh air circulation and place the dry ice outside the main cabin if possible.
Dry ice sublimates at different rates depending on temperature and container quality. Slabs may lose 2-10 % of their mass per day. One pound of dry ice produces 8.3 cu ft of CO₂ gas, so venting is critical. بعد الاستخدام, unwrap remaining dry ice and leave it at room temperature in a ventilated area until it fully sublimates. Do not put dry ice in sinks or toilets; extreme cold can damage plumbing.
