Water Filled Ice Packs
As the name suggests, water filled ice packs need to be filled with water from the water inlet and frozen. It’s essential in cold chain transportation because they are easy to use and cost-effective. Currently, the water injection ice packs have become a long-term consumable choice in many fields.

Structure of Raybo Water Injection Ice Pack
One-way Water Inlet
After filling with water and inverting the bag or after the internal gel forms, the water inlet automatically closes. No heat sealing machine or manual sealing is required, ensuring 100% leak-proof performance.
Double-sided PE film
The reinforced PE layer has industrial-grade burst resistance and can withstand heavy stacking during long-distance transportation. Moreover, during your use, the double-sided PE film will not stick or break.
Inside SAP material
The bag contains pre-filled high-purity SAP (superabsorbent polymer). The gel-like substance formed after water absorption has a very high specific heat capacity, extending the cooling time by 30%-50% compared to ordinary dry ice packs.

The Unique Advantages of Water-Filled Ice Packs
After water injection, the internal water pressure will squeeze the injection port from the inside out, achieving automatic sealing without the need for additional sealing steps. Even if the internal gel completely melts, it ensures no water leakage or gel leakage, preventing cargo damage and contamination caused by leaks during transportation. Water filled ice packs are ideal for industries with strict hygiene and safety requirements, such as pharmaceuticals and high-end food transportation.
The water injection port adopts a standardized industrial design, compatible with automated production lines on the market, supporting high-speed, large-volume filling operations. It is more suitable for large-scale application scenarios with high efficiency requirements, such as cold chain logistics, fresh food warehousing, ice bag for injection and distribution.
The injection ice pack is flexibly controllable within the marked range. Customers can freely adjust the water volume based on the required cooling duration, box space and ambient temperature. More water means larger volume and slower melting; less water saves space and is lighter and more flexible. If you are unsure about the required amount, our technical team can provide professional advice.
Using double-sided high-density PE film material, the surface is extremely smooth and does not stick to goods or other ice packs. There is no need to distinguish between the front and back sides or worry about adhesion damaging the packaging; they can be stacked freely and fit snugly against the goods. This not only makes the unpacking process cleaner and more professional but also improves efficiency during loading and transportation.
