Which packaging material is the safest

From a marketing perspective, the cosmetics industry has long understood the various mentalities of consumers, and knows how to cater to various consumer preferences. Therefore, you don't have to think too much about others as fools, but you are smart!
At first glance, there are a variety of packaging materials for skin care products on the market, excluding paper materials. Containers for skin care products are mainly plastic, glass and metal. Have you ever wondered which one is most used? Which one is most suitable for the most stable?
Plastics are the most used, with a proportion as high as 80%; glass is the second, with only 8%. And using more does not mean that plastic is more suitable for filling care products. The main reason is the high variability of plastics, which can be done in various sizes, shapes, colors, transparent and opaque. Light weight, easy transportation, good printability, and recyclability are all reasons for choosing plastic containers. The fate of plastics is heat resistance, insufficient light barrier properties, and poor solvent resistance (especially greases). Therefore, the first bottleneck that appears in plastic containers 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 maintenance items are not suitable for being packed in plastic containers.
Compared with plastic, the heat resistance, light resistance and solvent resistance of glass materials are absolutely superior. Therefore, unless the glass is of inferior quality, the best place for the care products is the glass container.
Metal materials are subject to many restrictions on the molding style. Most of the containers are cylinders (essential oil bottles) and wide-mouth bottles (lip balm). Most of the maintenance products are pure oil creams. Most of them are used as accessories such as bottle caps and bottle caps.
