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.
The slow growth of the glass packaging industry is not without reason. In terms of cosmetic packaging, competition from other materials and global economic growth are slow, but now it can be said that there has been a turning point. On the positive side, it benefits from the rapid growth of high-end skin care products and the high demand for glass products. In addition, cosmetic bottle manufacturers should also seek development opportunities from emerging markets and constantly update their products to meet customer requirements.
In fact, although the rise in raw materials and environmental protection and high pressure policies have greatly increased production costs, cosmetic bottle manufacturers are still very optimistic about the prospects of the glass packaging industry, and do not feel confident. On the contrary, most people believe that these competing packaging materials can't be compared with glass products in attracting customers and expressing brands and crystal positions.
The glass cosmetic container is transparent, which is a major advantage of its packaging. Compared to the metal packaging, it can display the packaged products in an unobstructed view, inspiring our desire to purchase. However, since glass cosmetic containers are used for the packaging of foods and medicines, some products have darkness requirements for packaging, such as juices, such as medicines. The requirements for protection from light will affect the shelf life of the products. There is a need to improve the light protection properties of glass cosmetic containers.
Currently, there are two main methods. One is to use colored glass bottles, such as essential oil glass cosmetic containers are packaged in dark glass cosmetic containers to meet the requirements of light protection. Another method is to improve the material of the transparent glass cosmetic container itself, and reduce the harm of light to the product through the absorption of light by the medium of the glass cosmetic container.
