Why Is a 24 Hour Dry Ice Pack Sheet Essential for Cold Chain Shipping?
Immediate answer: UM 24 hour dry ice pack sheet keeps sensitive products at sub zero temperatures without leaving any residue or moisture. Dry ice sublimates directly from a solid to carbon dioxide gas, so it doesn’t melt and cause water damage. This property makes it ideal for shipping frozen foods, pharmaceuticals and biologics that cannot tolerate thawing. Studies show that using dry ice can reduce spoilage rates by up to 75 %, improving product quality and reducing waste.
How Does Dry Ice Compare to Gel Packs?
Dry ice maintains lower temperatures than water based gel packs. Gel packs typically keep shipments at 2 - 8 °C, which is perfect for chilled goods like chocolate or fresh produce. No entanto, frozen products require temperatures well below 0 °C. Dry ice is made of carbon dioxide and is extremely cold at –78,5 ° C. (–109,3°F). Because it never melts into liquid, it keeps packages drier and lighter. Gel packs are better for items that only need to be cooled but not frozen; dry ice sheets excel when you need to keep goods frozen for 24 horas ou mais.
