TIL: Cardboard / gable top milk cartons are lined with... plastic. But they block ultraviolet light
Ultraviolet light can penetrate clear glass bottles (PDF) and HDPE (PDF) plastic bottles.
UV light degrades vitamins A and D and riboflavin.
*All of these packaging types are used for many other foods as well.
