At first glance, the bottles of skin care products on the market are a variety of materials. Excluding paper materials, the containers used to contain skin care products are mainly plastic bottles, glass bottles and metal materials. Have you ever wondered which one is most used? Which one is most suitable for the most stable?

The most used is the plastic bottle, the proportion is as high as 80%; the glass bottle is the second, only 8%. The use of more does not mean that plastic bottles are more suitable for skin care products. The main reason is that plastics have a high degree of change. All sizes, shapes, colors, transparent, and opaque can be done. Lightweight, easy to transport, good printability, recyclability, etc., are all reasons why plastic bottles have been chosen. The destiny of plastics is heat resistance, insufficient light barrier properties, and poor solvent resistance (especially oils and fats). Therefore, the first bottleneck that appears in plastic bottles is that they cannot be sterilized by high-temperature steam, cannot be washed with water, and cannot be sterilized by light. In addition, considering the stability of the contents, some items of skin care products are not suitable for plastic bottles.

Compared with plastic bottles, the heat resistance, light resistance, and solvent resistance of glass bottles are absolutely superior. Therefore, except for poor-quality glass bottles, the most suitable home for skincare products is glass bottles.

Metal materials in the molding style is subject to many restrictions, the container is mostly cylindrical (oil bottle), wide mouth bottle (lip balm)-based, filled with skin care products are mostly ointment, most of the time as caps, bottle caps and other accessories.
