Most of the general cosmetics appear as liquids, emulsions or pastes, and do not have a distinct appearance. It must pass through a beautiful, unique packaging design to express its own characteristics. Therefore, cosmetics generally rely on packaging to achieve good sales. Plastics and glass are currently the main cosmetic packaging container materials, and the amount of plastic is the most.
As far as the current situation is concerned, due to the light weight and low cost of plastics, it is easy to form 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, etc. print the instructions, logo, and barcode directly on the surface of the container. Therefore, plastic products have occupied more than 80% of the packaging market for cosmetics, becoming 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 with good design concepts, they are often not realized due to technical and material limitations.
Plastic materials are extremely advantageous in this respect. They are not only rich in source, 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 designed and decorated in various ways. In addition, in recent years, the rapid development of PET resin in cosmetic containers has led to a major revolution in replacing glass bottles with plastics.
