The first fresh cows’ milk in a carton

80% less plastic

If you’re looking to reduce your plastic waste, a simple switch to a2 Milk™ will be a great place to start. We are proud to be the first fresh cows’ milk to move from a plastic bottle to a sustainable carton that uses 80% less plastic. Now you can enjoy fresh cows’ milk that naturally contains only the A2 protein while doing your bit for the environment!

“I am writing to you today to say a huge thank you for getting rid of the plastic packaging! I’ve just read an article on it, hopefully it works out to be a great success! We love A2 milk and our family only drinks A2 milk.  So this would be a huge step towards reducing the amount of plastic we use as a household too – we go through 6 bottles a week!”

– Sandra

Plastic is a major issue is the UK and every effort is being made to reduce plastic bottle production. In the UK 38.5m plastic bottles are used every day – only just over half make it to recycling, while more than 16m are put into landfill, burnt or leak into the environment and oceans each day.*

Our carton

When we switched from a plastic bottle and launched our carton in September 2018, we took our first step on a sustainability journey. Our research showed us that over 2/3 of UK milk drinkers would prefer to buy fresh milk in a carton if they knew it was more sustainable. So here is a little bit more information about the badges of honour our fresh new carton carries…

Reducing plastic

The new a2 Milk™ carton uses 80% less plastic than our old plastic milk bottle. In fact, it’s the only fresh cows’ milk in the UK available in a carton.


The cartons consist of 80% paper board which is made using fibre from forests that are constantly replanted or regenerated. This means that the paperboard is 100% renewable and our carton carries the Forest Stewardship Council (FSC®) label.


The small amount of plastic that’s still needed to make the board water tight is 100% recyclable in the UK. To discover the best and easiest way to recycle an a2 Milk™ carton in your local area, visit the ACE UK website.

Carbon neutral

ISCC (International Sustainability & Carton Certification) certified. This means that the amount of carbon dioxide emitted into the atmosphere is reduced to zero because it is balanced by actions to offset these emissions.

The rectangular shape of the carton provides more space efficiency during transport and storage.


The high standard of a2 Milk™ is of the utmost importance to us, so rigorous testing has demonstrated that the new cartons safely preserve product contents and maintain nutritional value in the same way as a plastic milk bottle would.
