Mars Horsecare UK
SPILLERS Supplements

SPILLERS, part of Mars Horsecare UK and owned by Mars Inc., has long been the UK’s best-known horse feed brand. With a legacy of trust and quality, the team set out to launch their Supplements range — six targeted products designed to support specific horse health needs.

To achieve this, SPILLERS partnered with Law Print to deliver packaging that was both premium and recyclable. With 30% recycled content and manageable MOQs, the new packs not only protected the product but also reinforced Mars’ strong commitment to sustainability.

Unlike most products on the market, typically powders or liquids, SPILLERS’ supplements come in a unique pelleted format. This makes them more palatable for horses and far more convenient for owners, a point the new packaging needed to communicate clearly.

What did we do?

Client Overview
Mars Horsecare UK, part of the global Mars Inc. family, is the proud owner of SPILLERS — the UK’s best-known and trusted horse feed brand. With a heritage of excellence in equine nutrition, SPILLERS has long been a staple for horse owners nationwide.

The Product
Unlike most supplements in the category, which are typically powders or liquids, SPILLERS Supplements are produced in an innovative pelleted format. This makes them both highly palatable for horses and exceptionally convenient for owners to feed — a differentiator that needed to be clearly communicated through the packaging.

The Packaging Solution

1. Sustainability: 30% recycled content in the packaging material, achieved at manageable minimum order quantities — an essential factor for a new product range
2. Practicality: Strong, protective materials to maintain the integrity of the pellets
3. Added Value: A sustainable cardboard measuring scoop included in every bag, enhancing user convenience while eliminating the need for single-use plastic scoops

“Law Print has been a great partner in our SPILLERS Supplements launch. From our discussions, they grasped our business requirements and diligently worked to find solutions that met our needs, especially in aligning with our long-term environmental goals by ensuring any new plastic packaging includes 30% recycled content. Law supported us through the packaging development process and helped us in perfecting the designs. We are thrilled with the outcome; the bags feel high quality and truly stand out on the shelf. We’ve received positive feedback from both the trade and end users, and initial sales are going well”.

The Sustainability Imperative

The launch of SPILLERS Supplements demonstrates how thoughtful packaging design — grounded in sustainability, practicality, and brand alignment — can play a vital role in successfully launching a product range.  For Mars Horsecare, sustainability isn’t a trend — it’s a mission. That meant finding a packaging solution that didn’t just look good and protect the product but also reduced environmental impact. The challenge? Sourcing a supplier who could offer 30% recycled content in the packaging at a scale that made sense for a brand-new range.  The answer came from Law Print in the form of a collaborative packaging partner who ticked all the boxes.

More Than Just a Bag

The final packaging did more than hold pellets — it told a story. A story of a heritage brand innovating in a new market, of a company balancing premium quality with environmental responsibility, and of a launch that was as good for horses as it was for the planet.  When the SPILLERS Supplements hit the shelves, the reaction was instant. Horse owners loved the convenience of the pellets, the sustainable packaging resonated with eco-conscious customers, and the brand successfully established itself into a new category.  For SPILLERS, this wasn’t just a product launch — it was proof that even in an existing category, the brand could lead with innovation, care, and purpose.
