Which common cosmetic containers are safe for users?

In plastic bottle packaging, the advantages of PET bottles are more extensive. From edible oil to food, from medicine bottle packaging to cosmetic packaging, PET bottle packaging dominates almost all sizes. It is true that PET bottle packaging has many unique advantages that other plastic bottles cannot match. However, PET bottles also have some problems that need to be improved. Only by improving these problems can it be adjusted to ensure its leading position in the scale of plastic bottles and also in other packaging products such as glass bottles.

Plastics are mostly used in cosmetic containers, accounting for up to 80%, followed by glass, accounting for only 8%. And using too much does not mean that plastic is more suitable for filling skin care products. The main reason is the high variability of plastics, all sizes, shapes, colors, transparent and opaque can be done. Light weight, convenient transportation, good printability, and recyclability are the reasons why there are more choices of plastic containers. The fate of plastics is heat resistance, insufficient light blocking, and poor solvent resistance (especially grease). Therefore, the first bottleneck of plastic containers is that they cannot be sterilized with high-temperature steam, cannot be washed with water, and cannot be sterilized with light. Also, some care products are not suitable for packaging in plastic containers due to the stability of the contents.

Compared to plastic, glass-based cosmetic containers are absolutely superior in heat resistance, light resistance and solvent resistance. So unless it's low-quality glass, glass containers are fine for home care products.

Metal cosmetic containers are subject to many limitations in molding styles. The containers are mostly cylindrical (essential oil bottles) and jars (lip balm). The filled skin care products are mostly pure ointments, which are mostly used as bottle caps, bottle caps and other accessories.

The construction technology of recycled plastic has made great breakthroughs in the past few years. The recycling of plastic bottles dominates the recycling technology of plastic bottles, which greatly improves the acceptance rate of plastic bottles.
