What is a biodegradable dry ice pack sheet and how does it work?
Core concept explained: A biodegradable dry ice pack sheet is a flexible blanket of solid carbon dioxide encased in a biodegradable film. Each sheet contains cells filled with dry ice that sublimates directly from solid to gas at about −78.5 °C. Unlike gel packs that melt and release water, es kering tidak ada residu cairan. The biodegradable outer layer—often made from paper, cellulose or plant based polymers—breaks down naturally after use, menghilangkan sampah plastik. Karena lembarannya sesuai dengan kiriman anda, ini memaksimalkan efisiensi kontak dan pendinginan sekaligus mengurangi ruang kosong.
Why sublimation matters: Dry ice sublimation absorbs significant heat, keeping goods ultra cold for 24–72 hours. Selama sublimasi, 1 lb es kering menghasilkan sekitar 8.3 kaki kubik gas CO₂, so packaging must allow gas to vent to prevent pressure build up. The absence of meltwater means your products stay dry, and the biodegradable film prevents microplastics from entering the environment.
Anatomy of a biodegradable dry ice pack sheet
The sheet consists of three layers:
| Komponen | Bahan | Peran | Manfaat praktis |
| Biodegradable outer film | Kertas, selulosa atau polimer yang dapat dibuat kompos | Encases dry ice cells and protects products | Eliminates plastic waste and can degrade naturally |
| Dry ice cells | Co₂ solid | Sublimates at −78.5 °C, menyerap panas | Memberikan sangat dingin, pendinginan bebas kelembaban selama 24–72 jam |
| Fitur ventilasi | Perforasi atau saluran pernapasan | Biarkan gas CO₂ keluar dengan aman | Prevents pressure build up and complies with regulations |
Using biodegradable dry ice sheets: activation and packing
Preparing a biodegradable dry ice pack sheet is simple but crucial. Hidrasi lembarannya by immersing it in warm water and massaging the cells until fully expanded. This step activates the polymer matrix that holds the dry ice and improves flexibility. Freeze the sheet setidaknya 24 jam, ensuring it reaches the lowest possible temperature for maximum cooling. Pack the sheet inside your container with the fabric side facing the product and leave ventilation space for CO₂ gas to escape. Pre chilling products and choosing larger sheets for long journeys further extend cooling duration.
Practical tips and safety guidelines
Ventilasi penting: Use vented packaging or leave small gaps so CO₂ gas can escape. Sealed containers can explode due to gas pressure.
Lindungi diri Anda: Wear insulated gloves and protective eyewear when handling dry ice to avoid frostbite. Jangan pernah menangani es kering dengan tangan kosong.
Hindari ruang terbatas: Do not store dry ice in unventilated rooms or vehicles; Gas CO₂ dapat menggantikan oksigen dan menyebabkan mati lemas. Always allow fresh air circulation.
Gunakan wadah berinsulasi: Dry ice sublimates faster in warm or low pressure environments. Insulation reduces sublimation rate and prolongs cooling.
Kasus nyata: A pharmaceutical distributor shipped vaccines using a biodegradable dry ice pack sheet in a vented cooler. By hydrating and pre freezing the sheet, then layering it around the vials, they maintained −70 °C for 48 jam. Proper venting prevented pressure build up and staff used gloves and goggles. The shipment arrived without temperature excursions or packaging waste.
Why choose a biodegradable dry ice pack sheet?
