Cosmetic plastic bottles are mostly selected by many cosmetic production companies in the market, which is related to its own characteristics. Plastic bottles made of PE materials are not only low in cost, but also have strong manufacturability, and can be produced into various shapes. Cosmetics are biological agents, and have their own acid and alkali components, while plastic bottles can resist certain levels of acid and alkali.
In the cosmetics industry, plastic cosmetic bottles account for a large proportion because of their following characteristics:
1. Light weight: The density of materials used to make plastic bottles is small. Compared with the weight of containers with the same volume, plastic bottles are smaller than glass bottles.
2. Low cost: plastic can reduce the cost of raw materials and is lighter, so the total price is relatively cheap.
3. Combined with reliable sealing structure, the internal liquid can be better protected.
4. It has good mechanical strength. The mechanical properties of plastic bottles are slightly lower than those of glass bottles, but the common product packaging is sufficient.
5. Good shelf effect. The surface of the plastic bottle is easy to print, which is good for promoting sales.
6. The glass bottle cleaning process is reduced and the labor cost is effectively saved. At the same time, the use of plastic bottles can also effectively reduce the noise pollution in the production process.
7. Process problems: Compared with glass bottles, medical plastic bottles have more choices in terms of process and brand image, which is convenient to reflect various external design packages.
