As I have previously mentioned we are building a small room to dedicate to packaging 8oz packages for Amazon fulfillment. The owner has decided that there does not need to be a metal detector after the product has been packaged because after production prior to bulk packaging in a 40# box for warehouse storage it goes through a metal detector. However the bulk boxes will be dumped into a stainless steel hopper and delivery system into the bags.
My argument is there are still metal working parts the product is coming into contact with after it goes through the metal detector. Am I correct in the need for a metal detector and if so what ways can I convince him of the need for a metal detector on this new packaging line?
