How does a portable dry ice pack work?
Portable dry ice packs rely on phase change—freezing and sublimating CO₂ within the gel—to keep products cold. The super absorbent polymer absorbs water and turns it into a gel. عندما تجميد, the water and polymer create a matrix that can absorb dry ice gas as the ice sublimates. Because the pack stays flexible, it wraps around products, maximizing contact and slowing heat transfer.
Key operating principles
التحكم في درجة الحرارة مستقرة: Unlike traditional gel packs that become very hard and lose cooling efficiency when frozen, portable dry ice packs remain somewhat flexible. This flexibility improves their ability to stay in contact with irregularly shaped items
Long lasting cooling: Dry ice sublimates directly from solid to gas at around -78.5 درجة مئوية. Because the gas escapes through tiny pores, the pack maintains ultra low temperatures for extended periods.
لا بقايا سائلة: The sublimation process leaves no meltwater, reducing the risk of soggy packaging.
