What Is an Eco Friendly Dry Ice Pack Sheet and Why Does It Matter?
Direct Answer and Key Benefits
Sebuah eco friendly dry ice pack sheet adalah a flexible blanket of solid CO₂ encased in a biodegradable film. Each cell within the sheet holds dry ice that sublimates at about −78,5 °C, absorbing heat without leaving moisture and keeping goods frozen for 24–72 jam. The biodegradable outer layer—usually paper, cellulose or plant based polymers—breaks down naturally after use and eliminates plastic waste. Because the sheet conforms to your shipment, it maximizes contact and cooling efficiency while reducing void space.
Penjelasan yang diperluas
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 kertas, cellulose or compostable polymers, which decompose naturally. Because dry ice sublimates into a gas, there is no water consumption and no solid waste.
In cold chain logistics, these sheets excel for shipments requiring ultra cold temperatures (–20 °C hingga –70 °C). Unlike traditional dry ice pellets that may require hazardous material documentation, flexible sheets are often classified as non hazardous, menyederhanakan kepatuhan. 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.

Dispose or reuse responsibly: Allow remaining dry ice to sublimate in a ventilated area; compost or recycle the biodegradable film according to local guidelines. Inspect reusable sheets for damage and sanitize before the next use.
Safety Guidelines and Handling Tips
Es kering sangat dingin, 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 ° C., so touching it bare handed can cause frostbite. Selalu pakai protective gloves and goggles.
Storage matters: keep dry ice in a well insulated container, Tetapi never in an airtight vessel because sublimation will cause the container to rupture. Store it in a area yang berventilasi baik, 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. Setelah digunakan, 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.
