Most general cosmetics come in the form of liquids, emulsions or pastes and have no obvious appearance. It must express its own characteristics through a beautiful and unique packaging design. Therefore, cosmetics generally rely on packaging to achieve good sales. Plastic and glass are currently the main cosmetic packaging container materials, of which plastic is used the most.
Although cosmetics have many varieties and different functions, in terms of their appearance and packaging adaptability, they mainly fall into the following categories: solid cosmetics, solid particle (powder) cosmetics, liquid and emulsion cosmetics, and cream cosmetics. wait. Depending on the form, the packaging form is also different.
As far as the current situation is concerned, due to the light weight and low cost of plastics, it is easy to form large-scale production, and 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. directly print instructions, logos, and barcodes on the surface of the container. Therefore, plastic products account for more than 80% of the cosmetic packaging market and become 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 if there is a good design concept, it is often impossible to achieve due to the limitations of technology and materials.
Plastic materials are extremely advantageous in this respect. They are not only rich in sources, but also have good molding properties. They can be made into plastic containers such as bottles, jars 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 triggered a major revolution in replacing glass bottles with plastics.
However, we should also see that although the proportion of glass bottles in cosmetic packaging containers does not exceed 8%, they still have irreplaceable advantages in this packaging field and are still the preferred material for high-end cosmetics in the short term.
Purity, elegance, and elegance are the charms of glass bottles. Compared with plastic bottles, its heavy feeling makes people feel trustworthy. The unique visual effect of the frosted glass bottle is far from that of the plastic bottle.
Cosmetics, especially whitening and nutritional cosmetics, contain a lot of nutrients like food, but they are easily oxidized. This puts forward high requirements on the tightness of the packaging, and the barrier properties of glass bottles are undoubtedly better than plastic bottles in terms of protecting the contents.
