The three most common glass packaging colors for light-sensitive products

Glass packaging is one of the most popular choices for many different industries. Glass is scientifically proven to be chemically stable and non-reactive, which is why it holds a Generally Recognized as Safe (GRAS) status from the USA Food and Drug Administration.

UV light can pose serious problems for a variety of products. Whether you’re worried about food products sitting out on shelves or have a substance that simply can’t deal with UV exposure, it’s critical to invest in packaging for light sensitive products. Let’s analyze the most common glass colors and the importance these colors.

Amber glass

Amber is one of the most common hues for colored glass containers. Amber glass is made by mixing sulfur, iron, and carbon into the base glass formula. It became extensively manufactured in the 19th century, and is still extremely popular today. Amber glass is particularly useful when your product is light sensitive. The amber color absorbs harmful UV wavelengths, protecting your product from light damage. Because of this, amber colored glass is often used for beer, certain drugs, and essential oils.

Cobalt glass

Cobalt glass containers normally have deep blue colors. They are made by adding copper oxide or cobalt oxide into the mixture. Cobalt glass can provide enough protection against UV light because it can absorb more light compared to clear glass containers. But, this depends on the type of product you are packaging. It provides medium protection and just like amber, it can absorb UV radiation. But, it cannot filter blue light. 

Green glass

Green glass bottles are manufactured by adding chrome oxide into the molten mixture. You might have seen beer and other similar products packaged in green glass containers. However, it offers the least protection against the harmful effects of light compared to other tinted glass colors.Although green glass bottles can block some UV light, they cannot absorb light as much as cobalt and amber.
