The cosmetic bottle material is one of the packaging materials industry, which is divided into the whole package material and part of the packaging material.
The whole package material usually provides the drawings or general requirements of the cosmetics manufacturer, and is completely handed over to the packaging material manufacturer. The part of the packaging materials is divided into subtle and more detailed conditions and needs. It is divided into partial printing and capping materials. Bottle body packaging material. Depending on the type of cosmetic packaging, some small accessories can also be specifically outsourced. The cosmetics packaging industry and cosmetics are closely linked. Today, the overall homogenization of the cosmetics industry has increased the value of packaging materials. In recent years, industry insiders have also called for low-carbon, green packaging materials services.
Cosmetic packaging material classification
The full name is polyethylene terephthalate, which is the first material in the international material labeling number. Its main characteristics are high air tightness, good compressive strength, high water resistance and very transparent. 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. It is commonly used in packaging materials for food, beverage bottles and cosmetic bottles. Because of its high air tightness, the packaging container has no pores, so it is best to use it to make a container for packaging alcohol.
The full name of high-density polyethylene, also known as high-density PE, is the second material in the international material labeling number. Its main characteristics are good acid and alkali resistance. The product processed by it is translucent, and the heat resistance is not very good, and it is used to make the packaging container with capillary pores. It is often used in chemical packaging such as pharmaceutical bottles and cosmetic packaging materials.
The full name of polyvinyl chloride, which is the third material in the international material labeling number, its main characteristics are transparent, heat-resistant, before the advent of PET, it is to replace PET, used in mineral water, juice and other beverages, the biggest role at present It is used for the manufacture of water pipes for building materials and for the use of wires for the outer line of paint. The packaging material made of it has pores, so it is not suitable to use it for wine.
The full name of low-density polyethylene, also known as low-density PE, is the fourth material in the international material labeling number. Because it has low molecular density, it is softer than HDPE. The product processed by it is translucent and not Heat resistant, with pores, but it is acid and alkali resistant. Containers processed from such materials are commonly used in chemical and cosmetic packaging materials such as facial cleansers, salads, glue bottles, and cosmetic bottle hoses.
The full name of polypropylene, which is the fifth material in the international material labeling number, it is a high-density material, the product processed by it is translucent, heat-resistant, impact-resistant, acid and alkali resistant, but with capillary pores. It is often used in hot-filled packaged foods, microwave-cooked cooking utensils, microwave-grade processing of daily necessities such as high-temperature foods and general households, such as cups and cups, such as measuring cups.
Full name polystyrene, it is the sixth material in the international label material number. It is processed into a product with high transparency and good sealing, but it is brittle and not heat resistant. It is commonly used in the processing of sealed cans and food boxes.
The full name of polycarbonate, which is the seventh material in the international label material number, the products processed by it are transparent, heat resistant and not easily broken. It is commonly used in the processing of bottles, distillation tubs, heat-resistant barrels, and vials. It is the best in plastics, but its price is the highest among the seven products.
