1, PP, PE
It is an environmentally friendly 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. Depending on the molecular structure, it can reach three different degrees of softness and hardness.
2. PET
PET material is soft, the Chinese name polyethylene terephthalate, in the international material label number is the first material. Its main characteristics are high air tightness, good compressive strength, high water resistance, transparent, its transparency is as high as 95%, which is higher than the transparency of other commonly used plastic packaging containers, but not heat resistant. PET is an environmentally friendly material, can directly contact with cosmetics, food, is the main material for filling organic skin care products, commonly used as food, beverage bottles, makeup bottles packaging materials, but also because of high air tightness, packaging containers without pores, commonly used as alcohol packaging containers.
3. HDPE
The Chinese name high-density polyethylene, also known as high-density PE, is the second material on the international material label number. Its main characteristics are good acid and alkali resistance, hardness, tensile strength and creep are better than low-density polyethylene, and the products processed with it are translucent, poor heat resistance, and there will be capillary pores in packaging containers, which are often used in pharmaceutical bottles, cosmetic bottles shell packaging and other plastic products.
4. LDPE
The Chinese name of low-density polyethylene, also known as low-density PE, it is the fourth material on the international material label number, because of its low molecular density, it is softer than HDPE, and the products processed with it are translucent, heat-resistant, and have capillary pores, but it is good acid and alkaline resistance. Containers processed with this material are often used in chemical products such as facial cleanser, plastic water bottle, cosmetic bottle hose, etc.
5. PCTA
PCTA is a kind of copolymer polyester plastic raw material. With high transparency, excellent low temperature toughness, high tear resistance and good processing performance, excellent chemical resistance, can be electroplating, spray oil, scratch resistance, density is 16% lower than PC, processing cost is 40% lower than PC, printing, coloring, plating performance, toughness is 3 times higher than transparent ABS, in line with European RoHS environmental protection directive, suitable for high-grade cosmetic packaging.
6. PCTG
PCTG is a transparent plastic, with glass-like transparency and close to the density of glass, high gloss, chemical corrosion resistance, impact resistance, easy processing, injection molding, injection blow molding and extrusion blow molding. It can also produce unique shapes, looks and special effects, such as bright colors, matte, marble textures, metallic gloss, etc. It can be used as a source of packaging materials for perfume bottles and caps, cosmetics bottles and caps, lipstick tubes, makeup cases, etc.
7. AS
AS hardness is not high, more brittle (when hitting the crisp sound), transparent color, and the background color is blue, can be directly in contact with cosmetics, food, in the ordinary emulsion bottle vacuum bottle is generally used to make the material of the bottle, can also be used to make a small capacity of the cream bottle.
8. ABS
ABS belongs to engineering glass, is not environmentally friendly, the color is yellow or milky white, high hardness, can not directly contact with cosmetics, food, in the cosmetic packaging materials are generally used to make inner cover, shoulder cover material.
9. Acrylic
Also known as PMMA or plexiglass, it has good transparency, chemical stability and weather resistance, easy dyeing, easy processing, beautiful appearance, hard material, in order to maintain the transparent texture often into the bottle spray, or in the injection molding for color, often used in cosmetic bottle caps, bottle packaging.
These are the commonly used materials for cosmetic packaging materials, welcome to add.
