Water Filling

Water-Filled Ice Packs for Food Logistics: Cost-Effective & Reliable Cold

Why are water-filled cooling elements the premier choice for regular shipments?
Cooling elements with water filling are among the most versatile, eco-friendly, and cost-effective coolants in food shipping. Water features an excellent latent heat capacity that stores cold reliably and releases it uniformly. They are ideal for chilled shipping (0 to +8 °C / 32°F to 46°F) and serve as a vital thermal buffer in frozen shipping (0 to –18 °C / 32°F to 0°F). Used within our insulated cellulose-insulated boxes, they stabilize the microclimate over short and medium transit times.

The professional transport of temperature-sensitive goods requires efficient cooling systems that excel both ecologically and economically. Our water ice packs provide the perfect foundation for this. Whether shipping delicate pastries, meat, fresh fish, seafood, or dairy products – their rugged construction and high thermal stability dependably protect your food items from harmful external conditions during distribution.

Thanks to their extreme durability and resilient outer layer, these cooling elements are completely leak-proof, ensuring a sweat-free and clean application. They can be positioned flexibly inside the parcel to minimize empty spaces and combine flawlessly with adaptable thermal sleeves. For a precise requirements analysis and to determine the ideal coolant volume for your operations, our consulting team is always here to help.


Typical Applications for Water-Based Ice Packs

  • Standard Chilled Shipping (0 to +8 °C): Consistent temperature maintenance for sausages, cheese, delicatessen, and ready-to-eat meals requiring refrigeration.
  • D2C Logistics & Subscriptions: Sustainable and practical chilling solution for weekly grocery boxes, farm shop deliveries, and subscription kits.
  • Supplemental Frozen Transit (0 to –18 °C): Economical auxiliary cooling when paired with dry ice packs or gel packs to smooth out the thermal distribution.
  • Regional Distribution: Optimal cold chain stabilization for daily transits across short- and medium-distance shipping routes.

Why Choose BOXXCO Water-Filled Cooling Elements?

  • Dependable Thermal Retention: Ensures a uniform and long-lasting cold release inside the package.
  • Highly Economical & Durable: The exceptionally rugged outer film allows for endless re-use – perfect for closed-loop logistics.
  • 100% Clean Handling: Completely non-toxic pure water filling and leak-proof sealing protect your outer fiberboard boxes from moisture.
  • Universal System Integration: Fully compatible with all thermal boxes, insulated corrugated cartons, and fleece or foil inlays.

Frequently Asked Questions (FAQ)

How do you dispose of water-filled cooling elements eco-friendly?
Since the filling consists of pure water, it can be safely poured down the drain. The heavy-duty outer plastic film can then be easily recycled, making it a highly sustainable choice for end consumers.

How long do water ice packs need to be frozen before shipping?
To achieve peak thermal performance, the packs should be frozen completely for at least 24 hours, ideally at –20 °C. For best results, freeze them flat to maintain their uniform shape for easier packing.
