Looking for some feedback on checks when changing batches of packaging materials (Issue 7 6.2.3). We are a co-packer who doesn't do "rework", doesn't conduct changeovers within a production day, and considers all product produced on a line within a production day (between sanitation cleans) a batch. What I am unsure about is what should be used to identify a batch of packaging. The packaging suppliers batch or lot or can our Company define what we consider a batch? Or could this possibly mean batches of packaging for changeover situations?
Any input that could clear my confusion is much appreciated!
