All kinds of novel and exquisite packaging emerge in endlessly, such as: Airless Pump Bottles / Lotion Pump Bottle / Plastic Cream Jar / Plastic Spray Bottle / Foaming Soap Dispenser Bottle and so on. An excellent outer packaging and bottle body design seem to be an essential factor for the product to sell well. However, the role of cosmetic packaging is not just to attract consumers. For the material body, the packaging provides essential storage space and protection functions.
1. PP, PE
It is an environmentally friendly material that can be directly in contact with cosmetics and food. It is 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.
The PET material is relatively soft, and its Chinese name is polyethylene terephthalate. It 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 transparent shape. 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 environmentally friendly material that can be directly in contact with cosmetics and food. It is the main material for filling organic skin care products. It is often used as packaging materials for food, beverage bottles, and cosmetic bottles. Because of its high air tightness, the packaging container has no pores , often used as packaging containers for alcohol.
The Chinese name is high-density polyethylene, also known as high-density PE, which is the second material in the international material label number. Its main characteristics are good acid and alkali resistance, hardness, tensile strength and creep properties are superior to low-density polyethylene, and the products processed with it are translucent and poor in heat resistance. Capillary pores, commonly used in medicine bottles, cosmetic bottle packaging and other plastic products.
The Chinese name is 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. The products processed with it are translucent and not 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 chemical products such as facial cleanser, glue bottles, cosmetic bottle hoses, etc.
PCTA is a copolyester plastic raw material. It has high transparency, excellent low temperature toughness, high tear resistance and good processing performance, excellent chemical resistance, can be electroplated, oil sprayed, scratch resistant, density is 16% lower than PC, and processing cost is 40% lower than PC. Printing, coloring, and electroplating performance are good, and the toughness is 3 times higher than that of transparent ABS. It complies with the European RoHS environmental protection directive and is suitable for high-end cosmetic packaging.
PCTG is a transparent plastic with glass-like transparency and density close to glass, high gloss, chemical corrosion resistance, impact resistance, easy processing, and can be injection molded, injection stretch blow molded and extrusion blow molded. It is also capable of producing unique shapes, looks and special effects such as vibrant colors, frosted, marbled, metallic and more. It can be used as a source of packaging materials for perfume bottles and caps, cosmetic bottles and caps, lipstick tubes, cosmetic cases, etc.
AS hardness is not high, relatively brittle (there is a crisp sound when knocked), transparent color, and the background color is blue, it can be directly in contact with cosmetics and food, and it is generally used to make the bottle body in ordinary lotion bottle vacuum bottles The material can also be used to make small-capacity cream jars.
ABS belongs to engineering glass, which is not environmentally friendly. It is yellowish or milky white in color and has high hardness. It cannot directly contact with cosmetics and food. It is generally used to make inner covers and shoulder covers in cosmetic packaging materials.
Also known as PMMA or plexiglass, it has good transparency, chemical stability and weather resistance, easy to dye, easy to process, beautiful appearance, and hard material. In order to maintain a transparent texture, it is often sprayed inside the outer bottle, or during injection molding For coloring, it is often used in cosmetic bottle caps and bottle packaging.
