If you compare pure plastic bottles with glass bottles, it must be that glass bottles are more expensive and of higher grade, so glass bottles are commonly used in all kinds of alcohol and perfume products. Because the glass bottle has the attractive charm of thorough purity, elegance and nobility. At the same time, it also has a sense of heaviness, which makes people feel that the quality of cosmetics has been improved and brings a sense of trust. These are not available in plastic bottles. But in the cosmetics industry, plastic bottles have always accounted for a large proportion. The products of big brands like Este Lauder and Lancome are mainly packaged in plastic. So why are the big brands of cosmetics 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 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 reliably 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.
