Water-based ice packs
- Consistent cooling
- Eco-friendly solution
- Versatile usage
Sustainable cooling without compromise
Water-based ice packs are a reliable and eco-friendly cooling solution used across the food, medical, and pharmaceutical sectors. Engineered to maintain stable temperatures during transit, these packs are filled with non-toxic, water-based gel that freezes solid and retains cold for extended periods. At Hydropac, we specialise in producing high-performance water-based ice packs using our patented “seal through water” technology — ensuring leak-proof, hygienic, and consistent cooling. From shipping frozen foods and medicines to relieving soft tissue injuries, our water-based ice packs offer a sustainable and cost-effective alternative to traditional dry ice or chemical-based coolants, while aligning with strict cold chain and safety requirements.

Whether you’re shipping perishable food, transporting pharmaceutical goods, or requiring a cold therapy solution, these gel packs are the gold standard for performance, safety, and sustainability.
Why Water-Based Ice Packs Make a Difference
Water-based ice packs aren’t just about freezing water into a pouch—they represent a science-backed solution engineered for consistent thermal performance. Here’s what sets them apart:
- Long-Lasting Cooling Power
Thanks to their high latent heat of fusion, water-based packs absorb and retain cold energy longer, maintaining stable temperatures from -20°C to +8°C, depending on your specific needs. - Safe, Non-Toxic, and Food-Grade
Made from purified water and food-safe polymers, our ice packs are non-toxic, odourless, and suitable for direct contact with consumables, unlike dry ice or chemical refrigerants. - Flexible and Reusable
Available in a wide range of shapes and sizes—including ice sheets, bricks, and pillow packs—our water-based solutions adapt effortlessly to awkward payloads or custom packaging formats. Many are reusable, adding cost-efficiency to their appeal. - Eco-Conscious Cooling
Our packs are fully recyclable where facilities exist and require no special disposal procedures. Plus, our low-energy manufacturing process supports your green credentials.
Hydropac Technology: Innovation at the Core
Our ice packs are made using proprietary “seal through water” manufacturing—a method that enhances:
- Hygiene – No trapped air or contaminants during production

FAQ's about Water-Based Ice Packs
What are water-based ice packs made of?
Hydropac’s water-based ice packs consist primarily of purified water and food-safe thickening agents. This creates a gel-like consistency that ensures slow, even thawing, providing consistent cooling throughout transport. The outer film is robust, leak-resistant, and suitable for direct contact with products.
How long do water-based ice packs stay frozen?
The duration depends on usage and environment, but typically, our packs can maintain low temperatures for up to 24–48 hours when used with insulated packaging. For frozen shipments, we recommend pre-conditioning the packs at -18°C and combining them with insulation for optimal performance.
Are water-based ice packs safe to use with food and medicine?
Yes. Our packs are non-toxic, odourless, and meet food safety and pharmaceutical transport standards. They’re perfect for applications including fresh produce, dairy, meat, vaccines, biologics, and diagnostic samples.
Can I reuse water-based ice packs?
Absolutely. Hydropac’s packs are durable and built for multiple uses when handled correctly. After each use, simply refreeze them flat and inspect for any signs of damage or leaks before the next shipment.
Are these ice packs environmentally friendly?
Yes. In addition to being non-toxic and safe to dispose of with general waste (where permitted), our ice packs are made using low-impact manufacturing processes. We also offer recyclable and biodegradable options for eco-conscious operations.
