Chip giant Snack Brands is set to boost its supply chain operations with a new highly automated warehousing facility spanning 30,255 square-metres in Sydney's west.

Snack Brands announced last month it had secured a pre-lease facility in Sydney's Erskine Park which will be developed with the latest automated warehousing and distribution technology and will comprise a significant 35-metre-high bay section.

The new facility, located on First Estate Mamre Road Erskine Park by Altis, will have an end value in excess of $400 million.

Snack Brands Australia brands include CC’s, Thins, and Kettles and more, and the company said its new facility will transform its supply chain network.

“This facility will support our growth strategies and enable us to enhance our customer service at the lowest possible cost,” Snack Brands supply chain director Neville Tapp said.

Snack Brands worked with global supply chain and property consultancy TM Insight in the development of the concept plan for the new site.

TM Insight will project manage the delivery of the facility with stage one of the development due to be operational in late 2020.
