Woolcool pioneered the sustainable packaging revolution over two decades ago and have researched, and created innovative solutions for delivering perishable goods, ever since.

Unlike alternative solutions, there’s no need to compromise on sustainability or performance, when Woolcool offers both! We have harnessed the amazing natural properties of 100% sheep’s wool to provide insulation that delivers your products in perfect condition, without harming the planet.

Woolcool uses fully traceable materials and processes which are ISO certified to ensure consistent, clean, high-quality supply.

Other benefits of using wool includes its ability to absorb moisture from ice packs, preventing your products from arriving damp, and reducing damage from any accidental spills during transit. Its flexible nature also protects them from the impacts of courier delivery. 

Our rigorous cleaning process and the natural anti-microbial nature of wool also means that it has a much lower toxicity level when compared with alternative textiles.

We have specifically chosen to use materials that are compostable or recyclable, renewable, easy to dispose of and available in abundance, so that at the end of its life, our packaging does as little damage to the planet as possible. In fact, as wool composts it even adds nutrients back into the ground!

Due to the high performing nature of the materials we use, it also means that overall, our packaging uses less material and as a result, produces less waste compared to alternatives.

We were the first UK company in our sector to become B-Corp certified, are actively working towards meeting UN’s outlined Sustainable Development Goals and all of the paper and cardboard we use is FSC certified.

We’re proud that our packaging range is up to 95% plastic free, utilising natural materials such as wool and paper.

We are however very aware that it is important to use the right material for the right application, and all of our Woolcool® insulation liners are wrapped in a grade 4 recyclable polyethylene film. This is to ensure that they meet hygiene requirements for both food and pharmaceutical applications, and also to increase the reusability of the insulation. Due to the nature of our packaging being designed to work alongside ice packs, which produce condensation during use, waterproof materials also increase the durability of our packaging.

The additional bonus of wool is that it absorbs moisture really well to eliminate this moisture, and you may notice tiny perforations in our film which allow the wool to do this still, despite being wrapped.

We are always researching and staying at the forefront of developments of plastic alternatives in the sector, however we are also keen to fully ensure that a material is fit for purpose, as well as genuinely being better for the environment.

There are several ‘bio’ and ‘compostable’ plastic alternatives now available, but these often require very specific environments to break down, without which they can take many years to degrade just like traditional plastics. Whether they leave behind traces of bioplastics which can still be harmful to the environment, is also questionable and further long-term study is required.

For the time being, we have opted to use a material which our end users know how to dispose of correctly, with total transparency, until we are sure a better alternative is available.
