Workers at the Coca‑Cola plant in Edmonton, north London, were set to strike on Wednesday and Thursday of this week over pay.
The walkouts were planned to take place from 3pm until 9pm on both days.
The workers, in the Unite union, had planned to strike last week.
But the union called off the action for talks at Acas.
These talks have now broken down.
Workers are fighting a 2 percent, below-inflation pay deal. They rejected the deal and voted by 81 percent to strike.
