1、PP、PE
It is an environmental protection material, which can be directly in contact with cosmetics and food. It is the main material for packaging organic skin care products. The material is white and translucent. According to different molecular structures, it can reach three different degrees of hardness and softness.
2、PET
PET material is soft, and its Chinese name is polyethylene terephthalate, which is No. 1 material on the international material identification number. Its main characteristics are high air tightness, good pressure resistance, 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. Pet is an environmental protection material, which can directly contact with cosmetics and food. It is the main material for filling organic skin care products. It is often used as the packaging material for food, beverage bottles and cosmetic bottles. Because of its high air tightness and no pores in the packaging container, it is often used as the packaging container for alcohol.
3、HDPE
Chinese Name: high density polyethylene, which is commonly known as high density PE. It is material No. 2 on the international material identification number. Its main characteristics are good acid-base resistance, hardness, tensile strength and creep are better than low-density polyethylene. The products processed with it are translucent and have poor heat resistance. As a packaging container, there will be pores. It is commonly used in the shell packaging of medical bottles, cosmetic bottles 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 identification number. Because of its low molecular density, it is softer than HDPE. The products processed with it are translucent, heat-resistant, and have pores, but it has good acid-base resistance. Containers processed with this material are often used in chemical industries, such as facial cleansers, plastic bottles, cosmetic bottle hoses, etc.
5、PCTA
PCTA is a kind of copolyester plastic raw material. It has high transparency, excellent low-temperature toughness, high tear resistance, good processing performance, excellent chemical resistance, electroplating, oil spray, scratch resistance, density 16% lower than PC, processing cost 40% lower than PC, good printing, coloring, electroplating performance, toughness 3 times higher than transparent ABS, in line with European ROHS environmental protection directive, suitable for high-grade cosmetics packaging.
6、PCTG
Pctg is a kind of transparent plastic, which has the same transparency as glass and the density close to glass, high gloss, chemical corrosion resistance, impact resistance, easy processing, and can be injection molding, injection blow molding and extrusion blow molding. It can also produce unique shape, appearance and special effects, such as bright color, frosting, marble texture, metallic luster, etc. It can be used as the source of packaging materials such as perfume bottles and bottle caps, cosmetic bottles and bottle caps, lipstick tubes, cosmetic boxes, etc.
7、AS
The hardness of as is not high, crisp (there is a crisp sound when knocking), transparent color, and the background color is blue, which can be directly in contact with cosmetics and food. In ordinary lotion bottles, vacuum bottles are generally used to make bottle materials, and can also be used to make small capacity cream bottles.
8、ABS
ABS belongs to engineering glass, which is not environmental friendly. Its color is yellowish or milky white, and its hardness is high. It cannot directly contact with cosmetics and food. In cosmetics packaging materials, it is generally used to make inner covers and shoulder covers.
9. Acrylic
Also known as PMMA or plexiglass, it has good transparency, chemical stability and weather resistance, easy dyeing, easy processing, beautiful appearance, and hard material. In order to maintain a transparent texture, it is often sprayed inside the outer bottle, or painted during injection molding. It is often used in cosmetic bottle caps and bottle packaging.
