Arla is looking to increase production of Cravendale filtered milk by expanding one of the packaging facilities at its dairy in Stourton.

The company plans to spend £6.7m on a joint venture with blow-moulding company Logoplaste to make more milk bottles.

Arla said it hoped the new facility, which should be operational by March, would boost production of Cravendale by 50 million litres a year.

"Cravendale has doubled in value in the last four years," said brand manager Sam Dolan. "We expect value sales to exceed £166m by the end of the year."
