What are the types of plastics commonly used in cosmetic packaging?

The main packaging material in the cosmetic field is plastic containers, which are usually used for thick-walled cream bottles, caps, stoppers, gaskets, pump heads, and dust covers. Injection molding; PET bottle blowing is two-step molding. , The tube embryo is injection molded, and the finished product packaging is bottle blowing. At the same time, the core components such as the lip gloss tube plug/handle, pump head, spray, bottle cap and other core components are also plastic. Therefore, there is a deep bond between cosmetics and plastics. Here are some commonly used types of plastics:

1. ABS
ABS is an engineering plastic, which is not environmentally friendly and has high hardness. It cannot be directly contacted with cosmetics and food. In acrylic cosmetic packaging materials, it is generally the material of the inner cover and shoulder cover. The color is yellow or creamy white.

2. PP, PE
PP and PE are environmentally friendly materials, which can be directly contacted with cosmetics and food. They are the main materials for filling organic skin care products. The natural color of the materials is whitish and translucent. According to different molecular structures, three different degrees of softness and hardness can be achieved.

3. PET
PET is an environmentally friendly material that can be directly contacted with cosmetics and food. It is the main material for filling organic skin care products. The PET material is soft and its natural color is transparent.

4. PCTA, PETG
PCTA and PETG are environmentally friendly materials, which can be directly contacted with cosmetics and food. They are the main materials for filling organic skin care products. The materials are soft and transparent. PCTA and PETG are soft and easy to scratch. And it is not often used for multi-purpose printing

5. AS
AS is not high in hardness, brittle (there is a crisp sound when tapped), transparent color, and the background color is blue, which can be directly contacted with cosmetics and food. In ordinary lotion bottles and vacuum bottles, it is generally the material of the bottle body. Small-capacity cream bottles are also available. appear transparent.

6. Acrylic
The material is hard, transparent, and has a whitish background. In order to maintain a transparent texture, acrylic is often sprayed inside the outer bottle, or colored during injection molding.
