Some kinds of pink antistatic foam have been shown to transfer reactive fluorine compounds to silicon wafer surfaces during storage in humid conditions. This has resulted in corrosion of exposed aluminum bond pad surfaces, causing later assembly problems. I had direct experience with this at a former employer, and you can find similar reports in the literature if you search for them.
