1. PP, PE: These materials belong to environmental protection materials, which can directly contact with cosmetics and food, and are the main materials for packaging organic skin care products.

2. PET: Chinese name polyethylene terephthalate, which is the No.1 material in the international material label number. Its main characteristics are high air tightness, good compressive strength, high water resistance and very 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, and is often used as packaging materials for food, beverage bottles and cosmetic bottles. PET material can be recycled and is the main source of recycled materials.

3. PETG: PETG is an amorphous polyester, which is widely used in building decoration and materials. Its products are highly transparent, excellent in impact resistance, not easy to be broken and easy to be modified on the surface, reaching the food contact standard of FDA of the United States, and can be applied to the fields of food and medical products. PETG board substrates are all environmentally friendly materials, which meet the requirements of food contact management.

In short, when choosing cosmetic packaging materials, priority should be given to those recyclable, reusable and biodegradable materials to reduce environmental pollution.
