PP and PE
It is an environmentally friendly material, which can be directly contacted with cosmetics and food. It is the main material for packaging organic skin care products. The material is naturally white and translucent. Depending on the molecular structure, three different degrees of hardness and softness can be achieved.
PET
PET material is soft, in the international material labeling number is the first material. Its main characteristics are high air tightness, good pressure strength, high water resistance, and transparency, its transparency is up to 95%, higher than other commonly used plastic packaging containers that are transparent, but not heat resistant. PET is an environmentally friendly material, which can directly contact cosmetics and food. It is the main material for filling organic skin care products and is commonly used as the packaging material for food, beverage bottles, and makeup bottles. Due to its high air tightness and no capillary holes, PET is often used as the packaging container for alcohol.
HDPE
The second material is in the international material labeling number. Its main characteristics are good acid and alkaline resistance, hardness, tensile strength and creep is better than low-density polyethylene, processed with it made of products are translucent, heat resistance is poor, packaging containers will have pores, often used in medicine bottles, cosmetic bottles shell packaging and other plastic products.
LDPE
The fourth material in the international material labeling number, because it has low molecular density, so soft than HDPE, with it processed into products are translucent, heat resistant, capillary pores, but it is acid and alkaline resistance. Containers processed with this material are often used in chemical products such as cleansers, plastic water bottles, makeup bottle hoses, etc.
PCTA
PCTA is a kind of copolymer polyester plastic raw material. With high transparency, excellent low-temperature toughness, tear-resistance and good processability, excellent chemical resistance, electroplating, fuel injection, resist scratching, density is 16% lower than that of PC, processing costs 40% lower than that of PC, printing, coloring, electroplating performance is poor, toughness 3 times higher than transparent ABS, in line with the European RoHS environmental protection directive, suitable for cosmetics packaging.
PCTG
PCTG is a kind of transparent plastic, with glass transparency and close to glass density, high gloss, chemical corrosion resistance, impact resistance, easy processing, injection molding, injection pull blowing molding, and extrusion blowing molding. It can also produce unique shapes, looks and special effects, such as bright colors, scrub, marble texture, metallic gloss, etc. Can be used as a perfume bottle and bottle cap, cosmetic bottle and bottle cap, lipstick tube, cosmetic case, and other packaging materials sources.
AS
AS hardness is not high, more crisp (when hitting the sound of crisp), transparent color, and the background color blue, can directly contact with cosmetics, food, in the ordinary emulsion bottle vacuum bottle is generally used to make the material of the bottle body, can also be used to make the small capacity of the cream bottle.
ABS
ABS belongs to engineering glass, not environmental protection, color is yellow or milky white, high hardness, can not directly contact with cosmetics, food, in cosmetics packaging materials are generally used to make the inner cover, shoulder sleeve materials.
Acrylic
Also known as PMMA or Plexiglass, with better transparency, chemical stability and weather resistance, easy dyeing, easy processing, beautiful appearance, and hard material, in order to maintain the transparent texture often into the outside bottle spray, or in injection molding for color, often used in the cosmetics bottle cap, bottle packaging.
