The principle of vacuum packaging is: the cosmetic bottle is vacuumed until the internal oxygen is reduced to a safe amount or zero. This environment can effectively prevent the oxidation of active ingredients in the cosmetics and inhibit the growth of microorganisms, thereby delaying the deterioration of the cosmetics. This article will introduce you to the cosmetic packaging design. Cosmetic packaging design is more diversified. The most common packaging forms are plastic bottles, glass bottles, plastic tubes, etc. In recent years, due to the continuous emergence of various new plastic materials and the gradual development of composite film production technology, packaging composite films are also playing an increasingly important role in the design of cosmetic packaging, such as experience packaging, promotional equipment and poor Cosmetic packaging design forms such as travel. The packaging composite film is a new type of cosmetic packaging material, which is a multi-layer structure formed by a composite technology. Therefore, the packaging composite film has the advantage of other materials, which not only has excellent barrier properties and good convenience, but also meets the demand for exquisite appearance. The key to better functioning the packaging composite film is to implement the correct design. In terms of shape design, this cosmetic packaging design changes the traditional square box shape, but the box shape is designed into a triangle. The inner and outer double triangle nesting structure is uniquely designed. The inner triangular box is a product sales package, and the outer triangular box is a transport buffer protection box. The inner triangular box has a low height and is nested inside the outer triangular box, and is viewed from the top end. Two triangles form a "six-star" shape.
