Learn about the classification of materials commonly used in cosmetic packaging materials

1. PP, PE

It is an environmentally friendly material that can be directly contacted with cosmetics and food. PP bottle, PE bottle it’s the main material for packaging organic skin care products. The material is whitish and translucent. According to different molecular structures, three different degrees of softness and hardness can be achieved.

2. PET

The PET material is softer, and it is the No. 1 material on the international material label number. PET bottle's main characteristics are high air tightness, good compressive strength, high water resistance and transparency. Its transparency is as high as 95%, which is higher than that of other commonly used plastic packaging containers, but it is not heat-resistant.

3. HDPE

The Chinese name is high-density polyethylene, which is commonly known as high-density PE. It is the second material on the international material label number. Its main characteristics are good acid and alkali resistance, and its hardness, tensile strength and creep are better than low-density polyethylene. The products processed with it are translucent and have poor heat resistance. Capillary, commonly used in pharmaceutical bottles, cosmetic bottle shell packaging and other plastic products.

4. LDPE

The Chinese name is low-density polyethylene, also known as low-density PE. It is No. 4 material on the international material labeling number. Because of its low molecular density, it is softer than HDPE. It is heat-resistant and has capillary pores, but it has good acid and alkali resistance. Containers made of this material are often used in chemicals such as facial cleanser bottle, glue bottle, cosmetic tube, etc.

5. PCTG

PCTG is a transparent plastic with glass-like transparency and close to glass density, high gloss, chemical resistance, impact resistance, easy processing, and can be injection molded, injection stretch blow molding and extrusion blow molding. It can also produce unique shapes, appearances and special effects such as bright colors, frosted, marbled textures, metallic luster, etc. It can be used as a source of packaging materials for perfume bottles and caps, cosmetic bottles and caps, lipstick tubes, cosmetic boxes, etc.

6. AS

AS is not high in hardness, relatively 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. It is generally used to make the bottle body in the ordinary lotion bottle, airless bottle. The material can also be used to make small-capacity cream bottles.

7. ABS

ABS belongs to engineering glass, which is not environmentally friendly. Its color is yellow or milky white, and its hardness is high. It cannot be directly contacted with cosmetics and food.
