Here are some common types of plastics to make a little science:

1. ABS:

ABS is an engineering plastic, which is not environmentally friendly, has high hardness, and cannot directly contact 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 cream.

2. PP, PE:

PP and PE are environmentally friendly materials, which can directly contact cosmetics and food. They are the main materials for filling organic skin care products. The material is white and translucent. According to different molecular structures, three different soft and hard levels can be achieved.

3. PET:

PET is an environmentally friendly material that can directly contact cosmetics and food. It is the main material for filling organic skin care products. PET is soft and transparent in nature.

4, PCTA, PETG:

PCTA and PETG are environmentally friendly materials that can directly contact 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 hardness is not high, relatively brittle (clear sound when tapped), transparent color, and blue background can directly contact cosmetics, food, in ordinary lotion bottles, vacuum bottles are generally the material of the bottle body, Can also make small capacity cream bottles.
