Packaging for the Arla Milk range, designed by Blue Marlin, will clearly flag up the fat content of each variant.
The brand joins Cravendale and Lactofree in Arla's branded milk portfolio.
Separately, a £6m TV and press campaign for Cravendale by Wieden & Kennedy breaks on 9 April. The first ad features a cow, cyclist and pirate playing musical statues to see who should win the last glass of Cravendale. The strapline is 'It's not just any milk, it's filtered to make it purer'.
Blue Marlin declined to comment on the launch. Arla did not return calls.
