What Is a Dry Ice Alternative Dry Ice Pack Sheet?
A dry ice alternative dry ice pack sheet combines the ultra cold performance of traditional dry ice with the convenience of a reusable sheet. Each sheet contains multiple sealed cells filled with either CO₂ snow or engineered phase change material. Cuando se congele, the sheet provides temperatures between −20 °C and −60 °C for 36–72 hours. Unlike loose pellets that sublimate rapidly and leave residue, pack sheets encase the refrigerant to minimise CO₂ gas release and liquid runoff, making them easier and safer to handle. They are classified as non hazardous so you avoid many hazardous materials rules.
Dry ice pack sheets were developed to address the mismatch between rising dry ice demand and limited CO₂ supplythermosafe.com. By using less CO₂ and combining it with phase change material, they extend cooling duration and reduce emissions. Reusability means the same sheet can be hydrated, frozen and used multiple times, providing both cost and sustainability benefits. Because the refrigerant stays contained, pack sheets also reduce frostbite risk during packing and unpacking.
How Do Pack Sheets Compare to PCM Gel Packs?
Material de cambio de fase (PCM) gel packs absorb and release heat at specific temperatures. They typically maintain 2 °C a 8 °C o −20°C rangos, making them suitable for vaccines, biologics and clinical samples. A diferencia del hielo seco, PCMs are reusable and non hazardous, which simplifies compliance and reduces disposal. Gel packs melt more slowly and uniformly than water based ice, making them ideal for overnight or 48 hour shipmentstrans.info.
Hojas de hielo seco, por el contrario, deliver much colder temperatures (−20 °C a −60 °C) for 36–72 hours. They bridge the gap between gel packs and traditional dry ice, offering extended sub zero performance without the regulatory burdens of loose CO₂. When shipping mixed loads—such as frozen goods alongside refrigerated items—you can layer PCM packs above products and place dry ice pack sheets below to create separate thermal zones. This hybrid method reduces total CO₂ consumption while ensuring each product stays within its required range.
