Lions Prep

Healthy meals with sustainable packaging

As the UK’s highest rated meal plan service, Lions Prep is very serious about customer satisfaction. They deliver a wide range of healthy meals, including gluten-free and vegan options. Their focus on excellence extends beyond the high protein meals they supply for home delivery – packaging is important to them as well. It has to be convenient for the customer, safe for the food, and sustainable for the planet.

Customer needs


Constant improvement is a big part of Lions Prep’s success, and developing their offering to make sure customers receive the most sustainable packaging was a priority. They have set a goal for themselves to do everything possible to provide responsibly sourced packaging, across all of the products they deliver to customers’ homes.

Thermal protection

Ensuring both food safety and physical protection during transit was also vital. Meals had to be delivered completely undamaged, and in the right temperature range – while avoiding unsustainable packaging materials. The existing solution was a denim blanket, which can be prone to retaining moisture and food aromas and is difficult to recycle.


Lions Prep provides a complete dining experience, which includes receiving and unpacking the Meal Box. They wanted to enhance the experience by using a sustainable thermal liner, taking into account unboxing and how easy it is to recycle or dispose of packaging.

Our solution

After in-depth discussion of their needs and close technical support, Lions Prep chose RecyCold® climaliner™ as the most suitable replacement for their existing denim blankets. The new improved solution is the result of collaboration between Lions Prep, Ranpak, and the Distributor partner. Paper-based and entirely curbside recyclable, climaliner avoids the return or disposal of unwanted packaging. Thermal performance is excellent – Lions Prep needed up to 36 hours of protection, and the solution actually delivers up to 48 hours for ambient, chilled, and frozen products. The existing Lions Prep box could be used easily with the new insulation which is a thinner liner therefore maximizes box volume.

Business results

Unboxing experience

Lions Prep has improved the sustainability of their packaging while simultaneously enhancing the unboxing experience and maximizing convenience for consumers. They are well placed to continue growth in the healthy lifestyle market, with high-performance packaging that is easy to use and which conveys the right brand messages around sustainability.

Sustainable materials

RecyCold climaliner is made from paper, so it is recyclable, renewable, and biodegradable. The result is that consumers receive an effective and sustainable liner that keeps their meals cool.

Reduced damages

By keeping the products cooler for longer, there are fewer wasted meals – customers can have confidence that the meals they order will arrive in good condition.

Customer satisfaction

The new liners fit Lions Prep boxes superbly, ensuring safe transit and easy unpacking. They look great and work well. RecyCold climaliner has provided the business with a top-of-the-line thermal solution that pleases customers and safeguards the environment.

  • “RecyCold climaliner keeps our meals cooler, and because it’s compostable it is better for the planet and for our brand. Ranpak was very helpful in helping us find this solution, and our existing box now holds more.”
