:? I still have no answer to my question about the odor of the lids. Ball help line is certain that they do not contain BPA. Beyond that there was no explanation for the odor emited from the lids. I was asked to send one to them so they can check it. We will see. . . Currently there is no odor present. Puzzle. . .

Since the odor dissipated I would tend to believe the original box or case was exposed to something in the warehouse/truck/store and they retained that "aroma" for awhile. Still not good, but washing or rinsing in water would clean them of it. If it were the seals or something in the lid itself, it would not go away.
