Amber bottles are glass containers that have a rich, brownish color. This color is created by adding iron and other minerals during the glass-making process. The primary purpose of amber bottles is to protect their contents from harmful ultraviolet (UV) light, which can degrade certain substances, especially essential oils and pharmaceuticals. These bottles are commonly used in various industries, including cosmetics, food and beverage, and healthcare. Their ability to block UV light helps preserve the quality and potency of the products inside. Additionally, amber bottles are recyclable, making them an environmentally friendly packaging option.
