As a cosmetic bottle, the most ideal bottle is a bottle made of glass. In addition to good sealing performance and stable chemical properties, the cosmetic glass bottle can be used as a packaging for various high-grade cosmetics.
The glass bottle has good chemical stability and is not easy to react with the contents; it has good transparency, and can add coloring agents such as iron, cobalt and chromium to the raw materials to produce glass bottles of various colors (such as amber glass, green glass, blue glass, Cobalt blue glass, opal glass, opaque glass); good heat resistance and not easy to deform; high compressive strength, internal pressure resistance; high density, weight sense (suitable for higher-grade cosmetic packaging); barrier properties, hygiene and Good preservation, easy to seal, can be tightly sealed after opening. At the same time, however, the glass bottle has poor impact resistance, is fragile, has high filling cost, and is complicated in molding processing, which limits the application of the glass bottle. Glass bottles are often used in the packaging of high-end cosmetics or some special cosmetics.
Glass bottles generally used for liquid cosmetic packaging are generally small-mouth bottles (narrow-mouth bottles), which are mainly used for the packaging of nail polish, nail polish, perfume and flavor. The structure and shape of the glass bottle can be variously designed according to the needs of the product packaging, and can be realized by changing the mold at the time of manufacture. The bottle body can be directly printed or labelled. At the same time, glass bottles of different colors can be used to meet the packaging requirements of cosmetics with different characteristics.
