1 oz. (30 ml.) amber colored boston round glass bottle, 20 mm (20-400) neck finish, packaged with a black polypropylene (PP) plastic cap with a poly cone insert. The amber (brown) glass is able to filter out ultraviolet (UV) light and is primarily used for UV-sensitive products such as beer and some pharmaceuticals. Boston Rounds have a rounded shoulder and rounded base, making them popular in personal care packaging but also appropriate for applications in other industries. Glass offers excellent strength, weight and compatibility for materials that cannot use plastic containers. The cap's poly cone liner acts as a wedge insert that seals the lip and the inner neck of a bottle, providing extra protection from leakage.

Amber Glass - Made popular after the Civil War and now commonly known as the industry standard, the amber colored glass provides protection to light sensitive products such as, hydrogen peroxide and sulfuric acid chemicals, along with beer, oils, skin care, and pharmaceutical drugs by blocking out UV rays. It has wavelengths shorter than 450 nm (nanometers), allowing it to absorb most ultraviolet radiation. Amber glass is a tinted glass produced by combining iron, sulfur, and carbon. Due to its high level of carbon, amber is referred to as a reduced glass. The Cary Company stocks popular amber glass containers such as boston round and packer bottles.
