Hello, I work for Medical Device Packaging Mfg.- we make the rollstock that is used to make lids for medical device packaging. How should product be stored on the pallet? We currently wrap the roll in plastic, and put on the pallet. We were written up in a recent audit for this and I cannot find a regulation that states this. There is still a barrier of plastic wrap or a box with plastic wrap inside between the product. I would like to know for in-process raw material as well as finished goods. If a slip sheet is required (which I thought it was) it should be plastic correct and not cardboard? Thanks for the help!
