Ryan Armstrong, Unite regional officer, said: “Unite and Amcor have, after a long process, worked together as true partners, and this is reflected in an agreement that is acceptable to Unite members on the Salterbeck site.
“The agreement will allow for a flexible workforce that will hopefully return the Amcor site at Salterbeck to the pinnacle of the printing industry within the UK.”
Bosses last year said the restructure would help convert the business into a “healthy platform for growth serving the UK snacks and confectionery market”.
It did not give details of the reasons behind its proposals.
Amcor dates back to the 1860s, when Yorkshire stonemason Samuel Ramsden relocated to Australia and established Victoria’s first paper mill.
In the 1970s and 1980s it diversified the range of packaging products it created. It now operates more than 180 sites in more than 40 countries with 29,000 employees and describes itself as “a global leader in responsible packaging solutions”.
It supplies rigid and flexible packaging products into the food, beverage, healthcare, home and personal care and tobacco industries. Last month, staff at the factory produced thousands of Walkers crisp packets to commemorate Leicester football team’s Premier League championship.
Amcor supplies packaging for Pepsico, the company which owns the Walkers Crisps brand.
