The difference between glass bottle, hose and plastic bottle

Many customers don’t know much about cosmetic packaging materials, and don’t know the use and characteristics of glass bottles, hoses and plastic bottles in cosmetic packaging. Today, we have a brief understanding.

1. Glass bottles

Glass bottles used in cosmetics are mainly divided into skin care products (cream, emulsion), perfume, essential oil and nail polish. The capacity is small, basically less than 200ml, while glass bottles with a capacity greater than 200ml are rarely used in cosmetics. Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid paste generally uses wide-mouth bottles, which should be distributed with aluminum caps or plastic caps, and the caps can be used for color oil injection and other effects; Emulsion or water paste generally with narrow bottle, appropriate with pump head, such as with lid with internal plug, water with small hole internal plug, thicker emulsion with large hole internal plug.
