Which Packaging Material Is The Safest?

Feb 01, 2019

From the perspective of marketing, the cosmetics industry has long understood the various mentalities of consumers, and has long known how to recruit to cater to all kinds of consumer preferences. Therefore, you don’t have to think too much that others are fools, but you are smart!

At first glance, the quality of packaging materials on the market is varied. Excluding paper materials, containers for skin care products are mainly plastic, glass and metal. Have you ever thought about which one is used the most? Which one is best for the most stable?

The most used is plastic, the proportion is as high as 80%; the second is glass, only 8%. And much more does not mean that plastic is more suitable for filling skin care products. The main reason is that the plastic can be highly variable, and can be made in various sizes, shapes, colors, transparent, and opaque. Lightweight, easy to transport, good printability, and recyclability are all reasons why plastic containers are being used. The fate of plastics is not heat resistant, insufficient light barrier properties, and poor solvent resistance (especially greases). Therefore, the first bottleneck in plastic containers is that it cannot be autoclaved, cannot be washed with water, and cannot be sterilized by light. In addition, considering the stability of the contents, some skin care items are not suitable for being placed in plastic containers.

Compared with plastic, the heat resistance, light resistance and solvent resistance of glass materials are absolutely superior. Therefore, unless it is a poor quality glass, the most suitable home for skin care products is a glass container.

Metal materials are subject to many restrictions on the molding style. The containers are mainly cylindrical (essential oil bottles) and wide-mouth bottles (lip balms). The filled care products are mostly pure ointments, and most of them are used as caps, caps and other accessories.
