A water-activated hydrate dry ice pack sheet for cold-chain shipping programs that need longer low-temperature support for food, seafood, medical samples and route-tested insulated packouts.
Hydration coolant sheets for route-based cold-chain shipping
Hydration dry ice packs are built for cold-chain buyers who need a water-activated coolant sheet that can support food, seafood and medical sample routes. The sheet stores flat before use, absorbs water before freezing and can be placed around the payload inside a validated insulated packout.
Route-based cooling support
Designed for shipments where route time, ambient temperature and insulation must be considered together.
Longer low-temperature help
The source page describes up to 48 hours of support depending on packout, payload and insulation.
Flat dry storage
Dry sheets reduce storage and inbound freight volume before hydration.
Cut and fold layout
Cell seams allow the sheet to fit around products, carton corners and liner spaces.
Food and pharma use
Supports seafood, meat, prepared meals, medical samples and other temperature-sensitive shipments.
Custom packout matching
Tempk can match cell layout, sheet count and insulation format to the route requirement.

Where it fits best
Longer cold-chain routes
For food, seafood and sample shipments where transit time or ambient exposure is higher.
Validated insulated packouts
For buyers building a route-tested combination of coolant, insulation and payload arrangement.
Bulk distribution programs
For users who want flat dry storage before hydration and freezing at the packing site.
How to plan the packout
Define the route
Confirm route duration, expected ambient temperature and target product temperature before selecting sheet count.
Hydrate consistently
Soak the sheet until cells are fully expanded, then freeze before packing.
Build the packout
Place sheets around the payload inside a suitable insulated box, bag or liner.
Test before scale-up
Run sample shipments or temperature checks before using the packout for bulk orders.
Customization support
Route-specific sheet count
Adjust sheet count and layout for short routes, long routes or export shipments.
Packaging combination
Pair sheets with Tempk insulated bags, carton liners, medical cooler boxes or foam boxes.
Project documentation
Support sample testing, labels, packing instructions and carton configuration for bulk buyers.
Handling instructions
Soak the hydration dry ice pack in clean water for about 15 minutes, then freeze it completely before packing. Use enough sheet coverage for the payload size, route duration and insulation level.
For longer routes, validate the packout before mass shipping. Rehydrate the sheet if it becomes thinner after storage or repeated use, and remove damaged sheets from service.

FAQ
What is the main use of hydration dry ice packs?
They are used as water-activated coolant sheets in insulated cold-chain packouts for food, seafood, samples and other temperature-sensitive goods.
Can they support long routes?
They can support longer routes when sheet count, payload size and insulation are matched correctly. The final duration should be tested for the route.
Do they need water before freezing?
Yes. The sheet should be hydrated before freezing so the cells can expand and provide cooling capacity.
Can Tempk help with packout matching?
Yes. Tempk can help match sheet layout, insulation type and sheet count to the route and payload.
