Depending on the type of cosmetic packaging, it is also possible to outsource some small accessories. The cosmetics packaging industry and cosmetics are closely linked. Now the overall homogeneity of the cosmetics industry has increased the value of packaging materials. In recent years, the industry also calls for low-carbon and green packaging materials.
1---PET Chinese name polyethylene terephthalate, it is the No. 1 material in the international material label number. Its main features are high airtightness, good compressive strength, high water resistance, very transparent, and its transparency is as high as 95%, higher than that of other commonly used plastic packaging containers, but it is not heat resistant. It is commonly used in packaging materials for food, beverage bottles and cosmetic bottles. Because of its high airtightness, the packaging container has no pores, so it is best to use it as a container for packaging alcohol.
2 --- HDPE Chinese name high-density polyethylene, which is commonly known as high-density PE, it is the second material in the international material labeling number. Its main characteristic is good acid and alkaline resistance. The products made from it are semi-transparent, and the heat resistance is not very good. It is used to make the packaging container with pores. It is often used in chemical products such as: medicine bottles, cosmetics bottles packaging containers. 3 --- PVC Chinese name PVC, it is the No. 3 material in the international material labeling number, its main characteristic is transparent, heat-resistant, before the advent of PET, it is to replace PET, used in mineral water, juice Drinks, etc., currently have the largest role in the production of water pipes for building materials, and the use of wire lacquer wires. Containers made of it have capillary pores, so they should not be used to hold wine.
4 --- LDPE Chinese name low density polyethylene, also known as low density PE, it is the fourth material in the international material labeling number, because it has a low molecular density, so softer than HDPE, processed with it Translucent, heat-resistant, with pores, but it is good acid and alkali resistance. Containers made of this type of material are often used in chemical products such as facial cleansers, salads, bottles of glue, cosmetic bottles, and the like.
5---PP Chinese name polypropylene, which is No. 5 material in the international material labeling number, it is a high-density material, processed with it into a translucent product, heat resistance, impact resistance, acid and alkali resistant , but there are pores. It is commonly used for hot filling of packaged foods, microwaveable cooking utensils, high-temperature foods and general household face plates, mugs, and other daily-use microwave-grade processing such as measuring cups.
6---PS Chinese name Polystyrene, it is No. 6 material in the international marking material number, use it to process the product into a highly transparent, good sealing, but fragile, not heat-resistant. It is commonly used in the processing of sealed cans and food boxes.
7---PC It is No. 7 material in the international marking material number. The products made of it are transparent, high in heat resistance and not easily broken. It is commonly used in the processing of baby bottles, distilling barrels, heat-resistant barrels, and medicine bottles. It belongs to the best in plastic, but its price is the highest among the seven products.
