The distinguishing feature of glass cosmetic containers from other cans or paper containers is the transparency of the contents. However, it is because of this that the outside light can easily pass through the container, which causes the contents to deteriorate and deteriorate. In particular, ultraviolet light has a great influence on the contents, and it is urgent to develop a glass container which is colorless and transparent and can block ultraviolet rays. A colorless transparent glass called UVAFlint that absorbs ultraviolet light has been developed abroad to solve this problem.
In order to meet the needs of the market, more and more customers have put forward a variety of requirements, multi-function, small batch requirements for the color, shape and label of glass containers. It is in this situation that a film-coated glass container has appeared. The coated glass container also has the following advantages: it can prevent damage to the surface of the glass bottle caused by collision friction between the containers; it can cover the original fine scratches of the glass container, and the pressure resistance of the container can be increased by more than 40%.
The glass cosmetic container is large in quality and easy to be broken. In order to improve its competitiveness, it is a development direction to realize the lightweight and high strength of the glass container.
To reduce refractory stones, high quality refractory materials must be used. In general, the porosity, structural density, uniformity of microstructure, masonry quality, melting temperature, alkalinity of the glass itself, melting stratification, and the type of raw materials used are closely related to the refractory material. Common refractory stones are aluminum siliceous stones such as mullite, nepheline, leucite and the like.
As people's awareness of environmental protection has increased, a packaging container called "ecological glass bottle" is also an important development direction of glass containers in the future.
In recent years, the demand for glass packaging containers in the international market has shown a downward trend. In order to adapt to the fierce competition in the international packaging market, some foreign glass cosmetic container manufacturers and scientific research departments have continuously introduced new equipment and adopted new technologies to make glass cosmetic containers. The manufacturing has made a lot of progress.
