1. ABS:
ABS is an engineering plastic that is not environmentally friendly and has relatively high hardness, so it should not come into direct contact with cosmetics or food. In acrylic cosmetic packaging, it is typically used for inner lids and shoulder sleeves. Its color tends to be yellowish or off-white.

2. PP, PE:
PP and PE are environmentally friendly materials that can come into direct contact with cosmetics and food, making them the primary packaging materials for organic skincare products. The material has a naturally off-white, semi-transparent appearance. Depending on its molecular structure, it can achieve three distinct levels of hardness.

3. PET:
PET is an environmentally friendly material that can come into direct contact with cosmetics and food, making it a primary choice for packaging organic skincare products. PET is relatively soft, and its natural color is transparent.

4. PCTA, PETG:
PCTA and PETG are environmentally friendly materials that can come into direct contact with cosmetics and food, making them the primary choice for packaging organic skincare products. These materials are relatively soft and transparent; however, both PCTA and PETG are prone to scratching. Additionally, they are not typically used for screen printing—instead, they are more commonly finished with printed labels.

5. AS:
AS has low hardness and is relatively brittle (producing a crisp, clear sound when tapped), is transparent in color, and exhibits a bluish undertone, making it suitable for direct contact with cosmetics and food. In standard lotion bottles and vacuum‑sealed containers, it is typically used as the bottle material, and it can also be employed to manufacture small‑capacity cream jars. It appears transparent.

6. Acrylic:
The material is relatively hard, transparent, and has a whitish base color. Moreover, to preserve its transparent appearance, acrylic often undergoes internal spraying on the outer container or is colored during the injection-molding process.
