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. Transparency and gloss are quite popular, and transparent PET plastic bottles are now also becoming the packaging materials used by daily cosmetics and cosmetics manufacturers. With the improvement of people's cosmetics quality requirements, smart packaging will also receive more and more attention, and smart packaging materials play an important role in smart packaging technology. 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. The shape memory alloy can control the opening and closing of the product packaging according to environmental conditions. The piezoelectric material can provide a power source for the lighting material to emit light, and the smart adhesive is used in combination with the smart label to ensure the 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.
