Cobalt Blue vs Amber Bottles - Which Offers Better UV Protection for Bottles? Amber vs cobalt boston round bottles next to each other

This blog touches on the importance of glass packaging and protecting your product from UV light. We will explore the benefits of using tinted glass bottles, such as cobalt blue and amber colored glass, for blocking UV light and protecting light-sensitive products, such as essential oils, supplements, or medicine.

Does Clear Glass Offer Any UV Protection for Bottled Product?

Sunlight is made up of both UVB and UVA light. Depending on your product, exposure to UVA sunlight can cause damage, especially if it is highly light-sensitive. Glass packaging is an excellent way to protect your product from UV light. While clear glass offers some UV protection, tinted glass offers additional protection.

How Tinted Glass Can Help Protect Bottled Product

Tinted glass such as amber and cobalt blue can block UV light, which can help protect your product from unwanted damage. Green glass bottles, for example, are popular for protecting beverages but offer less protection from UV light than amber or cobalt blue. Similar to clear glass, green tinted glass can block visible light, that can cause discoloration or spoilage of your product.

A Tale of Two Tints: Cobalt Blue Glass vs Amber Glass

When it comes to tinted glass bottles, cobalt blue and amber glass are the most popular options. Cobalt blue glass is excellent for protecting your product from both visible light and UV light. This makes it an ideal option for light-sensitive products such as essential oils.

On the other hand, amber glass is known for its ability to block out UV rays. It can absorb light wavelengths shorter than 450 nm, making it ideal for products sensitive to UV light such as beer, spirits, or pharmaceutical products.
