To unswer your question, need to know what amplitude of voltage fluctuations you have? What errors are in your packaging machine is? What devices you have? What wiring scheme of your machine is? Your ask is very common.

As for servodrives, they could have save function from voltage fluctuations. You can turn it off for more stable work.
As for PLC, you need to supply it with UPC (more easiest way) and additional controle state and voltage of your executive devices.
