Available in Muller Wiseman Dairies Black and White packaging, the 100% British butter is made from cream and milk from Red Tractor approved British farms.
The new butter is available in various formats including salted and unsalted, both certified Kosher, with Unsalted also Halal approved.
Muller Wiseman Dairies managing director Carl Ravenhall said that launch of packet butter is a part of the company's strategy to add value to every drop of milk.
"Our business generates in excess of 90 million litres of excess cream each year, but investing in our butter offering means we now have much more flexibility and opportunity for innovation and expansion in how we add value to this cream."
Since 2013, Muller's BRC Grade A accredited butter processing plant in the UK has been producing the butter for the food ingredient and food manufacturing sectors.
