Discover HydroFreeze technology
Cooling that Works Harder, Smarter and Longer
HydroFreeze technology is more than just a formulation. It is the engine behind our most reliable cooling solutions. Developed in-house by Hydropac’s cold chain experts, HydroFreeze combines advanced gel science with practical packaging to ensure consistent thermal performance during transit. Whether you are shipping artisan cheeses or temperature-sensitive pharmaceuticals, HydroFreeze offers dependable cooling from dispatch to delivery.
How HydroFreeze Technology Delivers Exceptional Cooling Power
Unlike standard water-based packs, HydroFreeze gel packs are designed to absorb and retain cold more effectively. This results in a longer-lasting, more stable cooling effect for critical deliveries.
Key features include:
- Advanced Gel Formulation
Our proprietary gel formulation absorbs cold energy during the freezing process and releases it gradually to maintain consistent internal temperatures, even in fluctuating external conditions. - Reusable Reliability
HydroFreeze gel packs are made to withstand multiple freeze and thaw cycles without leaking or losing shape. Ideal for operations that require repeat usage or returnable packaging models. - Food-Safe and Leak-Resistant
Manufactured using food-grade materials and our seal through water technology, each pack offers a hygienic, durable seal that prevents leakage during use. - Streamlined Temperature-Controlled Shipping
When combined with insulation from our FreshPac or PharmaPac lines, HydroFreeze can maintain chilled or frozen conditions for up to 48 hours, depending on configuration and ambient temperatures.

FAQ's about HydroFreeze Technology
What is HydroFreeze technology made from?
HydroFreeze is a proprietary gel formulation developed by Hydropac. It is composed of non-toxic, food-safe materials designed to absorb and retain cold effectively. The gel remains flexible when frozen and provides controlled, gradual cooling during transit, making it ideal for chilled and frozen logistics.
How long do HydroFreeze gel packs stay cold?
The duration depends on the pack size, ambient temperature, and insulation used. When paired with appropriate packaging, HydroFreeze gel packs can maintain cold conditions for up to 48 hours or more. For highly temperature-sensitive shipments, we recommend combining them with our FreshPac or PharmaPac insulation systems.
Can HydroFreeze packs be reused?
Yes. HydroFreeze gel packs are manufactured for multiple use cycles. Thanks to their strong sealing and leak-resistant properties, they can be frozen and reused several times without losing performance or structural integrity. This makes them a cost-effective and sustainable choice for ongoing cold chain operations.
Are HydroFreeze packs safe for use with food and pharmaceuticals?
Absolutely. All HydroFreeze packs are produced using food-grade materials and are suitable for direct contact with outer packaging in both food and pharmaceutical logistics. They meet high hygiene standards and are free from harmful substances, ensuring safety throughout the cold chain.
What formats are available for HydroFreeze gel packs?
HydroFreeze technology is available across a wide range of formats, including flat packs, pillow-style gel packs, and rigid hard shell packs. These are offered in various sizes and volumes to suit specific product loads and shipment durations. Custom shapes and branding options are also available for large volume orders.
