Foods and beverages, personal care products and household cleaners packaged in clear polyethylene terephthalate (PET) bottles face a threat to their formulations and ingredients from ultraviolet (UV) light.
Exposure to sunlight and artificial light sources during warehousing, distribution, retail display and post-purchase storage can degrade the color, flavor, fragrance and nutritional value of consumer products. In particular, UV light can cause color fading and shifting, create off-flavors and aromas, and reduce vitamin potency. Ultimately, lower product quality and shorter shelf life resulting from UV damage can impact profitability and brand reputation.
