Why are all big-brand cosmetics bottles made of plastic?

If we compare pure plastic bottles and glass bottles, glass bottles are definitely more expensive and more upscale, so glass bottles are commonly found in various alcoholic beverages and perfume products. Because glass bottles have the seductive charm of thorough purity and elegance. At the same time, they also have a heavy feel, which makes people feel that the grade of cosmetics has been improved and brings a sense of trust. These are all things that plastic bottles do not have. However, in the cosmetics industry, plastic bottles have always accounted for a large proportion. Products of big brands such as Estee Lauder and Lancome are also mainly packaged in plastic. So why are big-name cosmetics in plastic bottles? Or why does the cosmetics industry favor plastic packaging bottles? I think the following points can explain this:

1. Light weight: The density of the material used to make plastic bottles is low. Compared with the mass of containers of the same volume, plastic bottles are smaller than glass bottles.

2. Low cost: Plastic can reduce the cost of raw materials and is also lighter, so the total price is relatively cheap.

3. Combined with a reliable sealing structure, the internal liquid can be reliably protected.

4. Good mechanical strength. The mechanical properties of plastic bottles are slightly lower than those of glass bottles, but common product packaging is sufficient.

5. Good shelf effect. The surface of plastic bottles is easy to print, which is very beneficial for promoting sales.

6. The cleaning process of glass bottles is reduced, which effectively saves labor costs. At the same time, the use of plastic bottles can also effectively reduce noise pollution in the production process.

7. Process issues. Compared with glass bottles, plastic bottles have more processes and brand impressions to choose from, which is convenient for the embodiment of various external design packaging
