Protecting Your Products from UV Light
t’s finally summertime! Although we all want to bask in the sunshine, it’s important to remember that your product may need extra protection from the sun. In this post, we'll discuss the impact harmful sun rays can have on products and what packaging options best protect products that are susceptible to damage from the sun.
WHAT IS UV LIGHT?
Ultraviolet (UV) light is a type of electromagnetic radiation that comes from the sun. It is the reason people get suntans, but also the reason people get sunburns. Just as too much exposure damages living tissue, UV light has a harmful effect on many products as well. UV radiation has enough energy to break chemical bonds, which can be detrimental to many types of products. Below, we list some examples of products that are sensitive to UV light and what packaging measures can be taken to protect them.
Years ago, it was common practice for apothecaries and pharmacies to store most items in amber glass vials. This is because amber glass completely blocks UV light, thus protecting the contents stored inside. In addition to blocking nearly all UV light, amber glass is also completely inert, meaning it won’t break down or leak chemicals into its contents.
Amber glass continues to be the best choice for packaging essential oils. When photo-oxidation occurs with essential oils, it can alter their scent, which is critical to the product.
