Over the years, China's cosmetics market has grown at an average annual rate of 15%, and it has begun to take shape. In 2002, the entire market realized 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 material in this market, plastics and glass will also have greater use. Most of the general cosmetics are presented as liquids, emulsions or creams and do not have a clear appearance. It must pass a beautiful, unique packaging design to show its own characteristics. Therefore, cosmetics generally rely on packaging in order to achieve good sales. Plastics and glass are the main cosmetic packaging materials currently used, and the use of plastics is the most common. Although there are various varieties of cosmetics and their functions vary, the following types are mainly related to their external appearance and the suitability of packaging: solid cosmetics, solid granular (powdered) cosmetics, liquid and lotion-like cosmetics, and creamy cosmetics Wait. According to different forms, the packaging form is different. As far as the current situation is concerned, because plastics are light and inexpensive, they are easy to form on a large scale. They can be made into a variety of sizes, transparent, opaque, and various colored bottles, and their printing performance is very good. Thermal transfer, ink jet, printing and other methods directly print the instructions, logos, and bar codes on the surface of the container. Therefore, plastic products have occupied over 80% of the packaging market for cosmetics and become the most important packaging containers for cosmetics. In the past, cosmetics were generally packaged in glass bottles. However, due to the single type of glass containers, even if they have a good design concept, they often cannot be achieved due to technical and material limitations. However, plastic materials have great advantages in this respect. Not only are they rich in sources, but they also have good molding properties. They can be manufactured into plastic containers of various structures and shapes, such as bottles, cans, and boxes, and can be used for various decorative and decorative designs. In addition, in recent years, the rapid development of PET resin in cosmetic containers has led to a major change in replacing plastic bottles with plastics. However, we should also note that although the proportion of glass bottles in cosmetic packaging containers does not exceed 8%, however, it still has irreplaceable advantages in this packaging field and remains the material of choice for high-end cosmetics in the short term. . Thoroughly pure, noble and elegant, is the charm of the glass bottle. Compared with plastic bottles, its heavy and heavy sense makes people feel more trust; and the unique visual effects of frosted glass bottles are even more unmatched by plastic bottles. Many perfume manufacturers have favored packaging their products with such containers. For example, BVLGARI's women's fragrances in Italy have adopted a packaging design that excels in the tradition of exquisite excellence. The streamlined frosted glass bottles highlight their simple lines. The soft green color conveys a fresh, elegant and friendly character. In addition, high barrier properties to gases also make glass bottles the preferred packaging materials for perfumes and other volatile, easily dissipating aroma products. Cosmetics, especially whitening and nourishing cosmetics, contain a lot of nutrients like foods, but they are extremely vulnerable to oxidation. This puts high demands on the tightness of the packaging, and the barrier of the glass bottle is undoubtedly better than the plastic bottle in terms of protection of the content. With the rapid development of modern industry and the continuous enhancement of public opinions on environmental protection, the application of paper packaging in commodities has become more and more extensive and the demand is increasing. Vacuum aluminum paper is one of them. Aluminized paper is mainly composed of base paper, aluminum layer and coating. It has good gloss and smoothness, good flexibility, high aluminum spray fastness, and beautiful environment protection. The main consumer groups of cosmetics are women. Whether cosmetic packaging is exquisitely affects the position of cosmetics in women's minds and their preference for specific brands. Vacuum aluminum-plated paper printing transparent colorful ink, can reveal the noble and rich metallic luster, while giving a psychological hint: After using this kind of cosmetics, they can also shine, and easy to print. Vacuum aluminum coated paper is easy to laser holographic processing, with a good anti-counterfeiting effect. According to the needs of different cosmetics on the packaging printed with a flash of laser LOCO or a specific beautiful pattern, both beautiful and fresh and easy to identify, but also prohibitive counterfeit products. However, for the current cosmetics market, packaging materials are still dominated by plastics and glass.
