With the rapid development of the cosmetics industry, cosmetic packaging materials occupy an important position in major shopping malls. Packaging materials play an important role in the storage, transportation and sales of cosmetics. Therefore, while paying attention to the development of cosmetics itself, we must also pay attention to the development of cosmetic packaging materials, including the development and selection of various materials, structural modeling. With decorating design and more. Cosmetic packaging materials include metal materials, paper materials, glass materials, plastic materials, and composite materials. As far as the current use situation is concerned, glass and plastic are the main materials for cosmetic packaging, and paper packaging materials are mostly used for cosmetic packaging. The transparency of cosmetic packaging is increasingly recognized by consumers, and CPP is the main material to meet this requirement. Compared with other transparent plastic resins, CPP media is cheap, competitive and has good performance.

Thermochromic materials can be used to indicate if the best or most dangerous temperature for product use has been reached. It is characterized by a change in color with temperature, that is, a color at room temperature, which changes color when heated or cooled, but returns to the original color when it reaches room temperature again. Smart materials and structures are also shape memory alloys, magnetically driven shape memory alloys, magnetostrictive materials and devices. Among them, shape memory alloy can control the opening and closing of product packaging according to environmental conditions. Piezoelectric materials can provide lighting power for packaging materials, and smart adhesives are used in combination with smart labels to ensure their freshness through discoloration. It is believed that with the maturity of the market and the improvement of the technological level, the choice of cosmetic packaging materials will be more widely distributed.
