- Reusable and Recyclable
Proven insulation with high-performance polystyrene boxes
When temperature-sensitive goods demand reliable thermal protection, polystyrene boxes provide a proven solution. At Hydropac, we supply high-performance polystyrene boxes designed specifically for cold chain use, ensuring chilled or frozen products stay protected throughout their journey. Lightweight, durable and food contact safe, our EPS (expanded polystyrene) boxes offer excellent insulation for both food and pharmaceutical applications. Integrated into our PharmaPac range, these moulded containers are ideal for pairing with ice packs and gel packs for a complete temperature-controlled system. Whether it is fresh produce, vaccines or frozen meals, Hydropac’s polystyrene boxes help deliver quality with confidence.
Discover Polystyrene boxes
The Smart Structure Behind Cold Chain Confidence
Hydropac’s polystyrene boxes are more than just containers. They are precision-moulded thermal systems that help maintain stable temperatures throughout the delivery cycle. Whether used in food distribution or pharmaceutical logistics, these boxes deliver the thermal integrity, safety and practicality required for modern cold chain operations.
Why Polystyrene is a Cold Chain Standard
Expanded polystyrene (EPS) offers a unique combination of thermal efficiency, moisture resistance and lightweight protection. At Hydropac, we use high-quality EPS to produce moulded boxes that are hygienic, durable and suitable for food or medical applications.
Benefits include:
- Exceptional Thermal Insulation
EPS slows down heat transfer by trapping air in its closed-cell structure. This keeps chilled and frozen goods within their ideal temperature range for extended periods. - Moisture Resistant and Durable
EPS is water-resistant, helping the box maintain its shape and protective properties even in damp or icy conditions. - Food Contact Approved
Our polystyrene boxes are manufactured using certified food-grade materials, making them suitable for direct use with perishables such as meat, fish, dairy and ready-to-eat meals. - Lightweight and Strong
The boxes offer robust cushioning and impact protection while remaining extremely light, helping reduce shipping weight and transport emissions. - Efficient Storage and Handling
Designed for stacking and compact storage, our EPS boxes make warehouse and vehicle space management easy and efficient.
A Greener Approach to Frozen Packaging
Hydropac’s polystyrene boxes are often used in combination with our HydroFreeze and EasiFreeze cooling systems. These gel-based and phase-change solutions are engineered to maintain conditions below 0°C, making them suitable for frozen and deep-chill applications.
Unlike dry ice, HydroFreeze and EasiFreeze are:
- Non-toxic and food safe
- Reusable and recyclable
- Safer to handle with no risk of carbon dioxide exposure
- Better for the environment due to zero sublimation emissions
These cold packs provide a cleaner, safer and more sustainable way to protect temperature-sensitive products. Together with our EPS boxes, they form a complete packaging solution that aligns with sustainability goals without compromising on performance.

FAQ's about Polystyrene Boxes
Are Hydropac’s polystyrene boxes recyclable?
Yes. Hydropac’s polystyrene boxes are made from expanded polystyrene (EPS), which is 100% recyclable. EPS can be repurposed into insulation panels, packaging materials and other products through specialist recycling facilities. While kerbside collection varies, we always encourage responsible disposal via local recycling schemes where available.
What products are polystyrene boxes suitable for?
Polystyrene boxes are ideal for transporting temperature-sensitive goods such as chilled or frozen food, pharmaceuticals, diagnostic samples and meal kits. Their thermal performance makes them suitable for both short and extended journeys when used with cooling elements like HydroFreeze or EasiFreeze.
How long can polystyrene boxes maintain cold temperatures?
When combined with the right refrigerants and insulation configuration, Hydropac’s polystyrene boxes can maintain chilled or frozen conditions for 24 to 48 hours or more. Performance will depend on ambient temperatures, pack size and the number of cooling elements used.
Can these boxes be reused?
Yes. Hydropac’s EPS boxes are designed to be durable and reusable. With proper handling and storage, they can maintain their structural and thermal integrity over multiple delivery cycles. Reuse is especially common in internal logistics and closed-loop systems.
What sizes and formats are available?
Hydropac offers a wide range of polystyrene box formats, including moulded standard sizes, euro-sized boxes, and custom-fabricated options. We also supply low-volume flat-pack boxes and bespoke shapes to meet specific operational needs. All boxes are compatible with our gel pack solutions for complete temperature control.
