Best in Class screening yield. ## Protect. Unpack. Recycle. No vague environmental promises. No complicated sustainability story, just high-performance insulation, backed by independent evidence. When it comes to recyclability, we don't think you should just claim it, you should prove it. EcoCool encapsulated liners were tested by an independent paper laboratory under conditions that simulate a conventional paper recycling mill. They achieved a total screening yield of 96.6%, the share of the material that passes through the mill's screens, rated Best in Class, and a Technical Recyclability Score of 91/100. **Putting all of this testing together, we have a product that is not only kerbside recyclable and rated GREEN for UK RAM, but also rated Best in Class under independent recyclability review.** **Ask your supplier for their recyclability report. Ours is available on request.** Independent recyclability review **Rated Best in Class** Kerbside recyclable Recyclability test details - Laboratory: Inštitut za celulozo in papir (ICP), Ljubljana, Slovenia - Method: Paper and Board Recyclability Laboratory Test Method, Part I: Recycling mill with conventional process, Version 3, February 2025 - Report: P-N26-269-MT, 13th October 2026 - Result: technically recyclable in a recycling mill with conventional process - Technical Recyclability Score: 91/100 - Total screening yield: 96.6%, Best in Class - Evaporation residue: Best in Class - Sheet adhesion: minor issues. Visual impurities: no quality issues - Results apply to the samples tested The real question ## Sustainable insulation is only sustainable if it works We get it. There are plenty of low-cost paper insulation options that look sustainable. The real question is whether the complete pack-out protects your product in real conditions, on a real route. Polystyrene, loose paper fill, cotton, jute and unrecyclable fibres each solve part of the problem. However, EcoCool has been built to perform across supply chain requirements: protect the product first, then make the box easy to recycle. - Polystyrene - Loose paper fill - Cotton - Jute - Unrecyclable fibres Each solves *part* of the problem. EcoCool® Built to perform across the whole supply chain. Inside EcoCool ## Engineered from cardboard. Designed for protection. A durable outer paper liner encapsulates a compressed, bound paper-fibre core. This structure combines cushioning protection with thermal insulation. ![](https://info.hydropac.co.uk/hs-fs/hubfs/EcoCool/ecocool-zoom-outer.png?width=400&height=400&name=ecocool-zoom-outer.png) ***1*Durable outer liner**Tough, moisture-resistant kraft paper provides strength and durability for the rigours of the cold chain, while remaining fully kerbside recyclable. 100% Kerbside recyclable ***2*100% kerbside recyclable**Manufactured from clean, never-before recycled corrugated waste, EcoCool can be disposed of alongside standard household cardboard packaging. ![The EcoCool paper-fibre liner, open](https://info.hydropac.co.uk/hubfs/EcoCool/ecocool-liner.png "The EcoCool paper-fibre liner, open") 1 2 3 4 ![](https://info.hydropac.co.uk/hubfs/EcoCool/ecocool-zoom-core.png) Tap a point to look inside ![](https://info.hydropac.co.uk/hs-fs/hubfs/EcoCool/ecocool-zoom-core.png?width=400&height=400&name=ecocool-zoom-core.png) ***3*Innovative insulating core**Uniquely engineered from compressed and bound cardboard offcuts, to form a cushioning, protective, insulating thermal liner. ![](https://info.hydropac.co.uk/hs-fs/hubfs/EcoCool/ecocool-zoom-layers.png?width=400&height=400&name=ecocool-zoom-layers.png) ***4*Sustainable engineering at its best**A cushioning, protective and super-insulated liner system.

Product surface stayed below 8°C. In laboratory chamber testing, a large EcoCool pack-out was loaded with minced meat chilled to 4°C and four frozen ice packs, then held for 48 hours in a chamber cycling between roughly 20°C and 25°C. Over that time the product surface temperature stayed below 8°C. **48 hours**Duration **Below 8°C**Product skin **20–25°C**Ambient Both boxes Large box Small box Laboratory chamber profile, 48 hours The chamber cycles between 20 and 25 degrees.

That's the right question, and it depends on the whole pack-out, not the liner alone. We prove the combination of liner, coolant, payload and box against your product, route and temperature requirement before you commit. What's it made from? Clean, unused cardboard offcuts, formed into a soft liner that fits a standard box. Do I still need coolant? Yes. EcoCool insulates and cushions, and coolant does the cooling. Hydropac has the range to match it to your pack-out. Can it go in normal recycling? It's designed for kerbside recycling, so it goes in with the box. How do I know it's recyclable? We had it tested! An independent paper laboratory tested the EcoCool encapsulated liner under conditions that simulate a conventional paper recycling mill. It scored 91/100 for technical recyclability, with a Best in Class screening yield. We'll share the report on request. What can I do with it after use? Beyond recycling, we're exploring second-life uses like loft insulation and animal bedding with early customers. Register to be part of that. When can I get it? Early access opens 4th November. Register now to secure your stock for Christmas.
