The investor beat the competition in a process launched more than a year ago. Italian engineering group Coesia, German industrial holding Koerber as well as private equity firms KKR and Bain had also handed in final bids by a mid-June deadline, several people close to the matter had said.

Bosch and CVC declined to comment on the deal, which was earlier flagged by the Wall Street Journal.

Bosch put the business on the block as part of a portfolio overhaul which will see it emphasise electric and autonomous car technologies.

The Bosch business, which competes with Italy's IMA, makes machines for pharmaceuticals and food packaging, employs 6,100 staff and has revenues of about 1.3 billion euros ($1.5 billion).

The car industry and its suppliers have come under pressure to accelerate investment in electric and self-driving vehicle technologies, following a regulatory crackdown on diesel.

The packaging industry has seen a wave of consolidation in recent years with private equity groups being drawn to the stable cash flows of the firms, which tend to grow in line with gross domestic product, and who have so far seen limited impact from the debate about plastic pollution in the world's oceans.

Last week, Aurelius sold packaging maker Solidus to Centerbridge for 330 million euros.
