Over the years, China's cosmetics market has grown at an average annual rate of 15% and has now begun to take shape. In 2002, the entire market achieved a total sales of 45 billion yuan. It is predicted that the total sales of its market in 2010 will reach 80 billion yuan. As the main packaging materials in this market, plastic and glass will also have a greater role. Most of the general cosmetics are in the form of liquid, emulsion or paste, and do not have a distinct appearance. It must express its own characteristics through beautiful and unique packaging design. Therefore, cosmetics generally rely on packaging to achieve good sales. Plastic and glass are currently the main cosmetic packaging container materials, and among them, plastic is the most used.

As far as the current situation is concerned, due to the light weight and low price of plastic, it is easy to form large-scale production, and it can be made into bottles of various sizes, transparent, opaque and various colors, and the printing performance is very good. Thermal transfer, inkjet, printing and other methods directly print instructions, logos, and barcodes on the surface of the container. Therefore, plastic products have occupied more than 80% of the packaging market of cosmetics and become the most important packaging container for cosmetics. In the past, cosmetics were generally packaged in glass bottles. However, due to the single variety of glass containers, even if there is a better design concept, due to technical and material limitations, it is often impossible to achieve.

However, plastic materials have great advantages in this regard. They are not only rich in sources, but also have good molding properties. They can be manufactured into plastic containers such as bottles, cans, and boxes of various structures and shapes, and can be decorated and designed. Coupled with the rapid development of PET resin in cosmetic containers in recent years, it has led to a major change in replacing glass bottles with plastics.
