Glass bottles are often used in the packaging of high-grade cosmetics

Glass bottles have good chemical stability and are not easy to react with the contents; good transparency, can be added in raw materials such as iron, cobalt, chromium and other colorants to produce a variety of color glass bottles (such as amber glass, green glass, blue-white glass, cobalt blue glass, opal glass, opal glass); good heat resistance and not easy to deform; high compressive strength, high internal pressure; high density, a sense of weight (moderate). It can be packed in high-grade cosmetics, with good barrier, hygiene and preservation, easy to seal, and can be sealed again after opening. But at the same time, the glass bottle has poor impact resistance, fragility, high filling cost and complex forming process, which limits the application of glass bottles. Glass bottles are often used in the packaging of high-grade cosmetics or some cosmetics with special requirements.
There is no reason why the growth of glass packaging industry is slow. Take cosmetic packaging for example, competition from other materials and global economic growth are slow, but now it can also be said that there is a momentum of improvement. On the positive side, it benefits from the rapid growth of high-end skin care products and the large demand for glass products. In addition, cosmetic packaging bottle manufacturers should also seek opportunities for development from the emerging market and constantly update their products to meet customer requirements.
In fact,although the rising raw materials and environmental protection policy have greatly increased production costs, cosmetic bottle manufacturers are still optimistic about the prospects of glass packaging industry, and do not feel confident enough. On the contrary, most people believe that these competing cosmetic packaging materials can not be compared with glass products in terms of attracting customers, brand performance and crystal location.
Glass cosmetic containers are transparent, which is a major advantage of packaging. Compared with metal packaging, glass cosmetic containers can display the packaged products at a glance and stimulate our desire to buy. However, because glass cosmetics containers are used for packaging of food and medicine, some products need to avoid light, such as fruit juice and medicine. The requirements of these products will affect the quality cycle of products, which requires improving the light-proof performance of glass cosmetics containers.
At present, there are two main ways. One is to use colored glass bottle packaging, such as essential oil glass cosmetics container is to use dark glass cosmetics container packaging, to achieve the requirements of light protection. Another way is to improve the material itself of transparent glass cosmetics container, through the absorption of light by glass cosmetics container layer media to reduce the harm of light to products.
