The major feature of glass cosmetic containers, which is different from other cans or paper containers, is the transparency that allows the contents to be clearly seen. But precisely because of this, light from outside can easily penetrate the container, causing the contents to deteriorate and deteriorate. In particular, ultraviolet rays have a great impact on the contents, and there is an urgent need to develop a colorless and transparent glass container that can shield ultraviolet rays. A colorless and transparent glass called UVAFlint that can absorb ultraviolet rays has been developed abroad to solve this problem.
In order to meet the needs of the market, more and more customers have put forward multi-variety, multi-functional, and small-batch requirements for the color, shape and label of glass containers. It is in this situation that coated film glass containers appeared. The film coated glass container also has the following advantages: it can prevent the surface of the glass bottle from being damaged due to collision and friction between the containers; it can cover the original fine scratches of the glass container and increase the compressive strength of the container by more than 40%.
Glass cosmetic containers are large in quality and easy to break. In order to improve their competitiveness, achieving lightweight and high strength glass containers is a development direction.
To reduce refractory stones, high-quality refractory materials must be selected. Generally speaking, the porosity of refractories, structural density, uniformity of microstructure, masonry quality, melting temperature, alkalinity of the glass itself, melting stratification, and the types of raw materials used are closely related to it. Common refractory stones are alumina-siliceous stones such as mullite, nepheline, leucite, etc.
With the increase of people's awareness of environmental protection, a packaging container called "ecological glass bottle" is also an important development direction for glass containers in the future.
In recent years, although the demand for glass packaging containers in the international market has been declining, in order to adapt to the fierce competition in the international packaging market, some foreign glass cosmetic container manufacturers and scientific research departments continue to introduce new equipment and adopt new technologies to make glass cosmetic containers A lot of progress has been made in the manufacture of.
