Latest company news about Classification of cosmetic packaging materials
Friends who are engaged in cosmetic packaging materials know that cosmetic packaging materials are a kind of packaging materials industry, which are divided into overall packaging materials and partial packaging materials.
 
The whole packaging material refers to that the cosmetics manufacturer will provide drawings or put forward general requirements, and then completely hand over to the packaging material manufacturer for production. Some packaging materials are divided into fine parts, which can be divided into local printing, bottle cap packaging materials and bottle body packaging materials, depending on the specific situation and the needs of cosmetics manufacturers. Depending on the type of cosmetic packaging, you can also outsource some small accessories. The cosmetics packaging industry is closely linked with cosmetics, and the overall homogenization of the cosmetics industry has increased the value of packaging materials. In recent years, industry insiders have advocated providing low-carbon and green packaging materials services.
 
The materials of packaging materials can be divided into the following types:
 
1、PET
 
The Chinese name is polyethylene terephthalate, which is material No. 1 on the international material identification number. Its main characteristics are high air tightness, good pressure resistance, 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 as packaging materials for food, beverage bottles, and cosmetic bottles. It is precisely because of its high air tightness and no pores in the packaging container, which is often used as the packaging container of alcohol.
 
2、HDPE
 
Chinese Name: high density polyethylene, which is commonly known as high density PE. It is material No. 2 on the international material identification number. Its main characteristic is good acid-base resistance. The products processed with it are translucent and have poor heat resistance. When used as packaging containers, there will be pores. It is often used as packaging containers for chemical industries such as pharmaceutical bottles and cosmetics.
 
3、PVC
 
The Chinese name is PVC, which is No. 3 material on the international material identification number. Its main characteristics are transparent and heat-resistant. Before the advent of pet, it was often used as the packaging material for mineral water, fruit juice and other beverages. At present, the largest application is to make the enameled outer wire of water pipes and wires for building materials. The container made of it will have pores, so it is not suitable for wine.
 
4、LDPE
 
Chinese name low density polyethylene, also known as low density PE, is No. 4 material on the international material identification number. Because of its low molecular density, it is softer than HDPE. The products processed with it are translucent, heat-resistant and have pores, but it has good acid and alkali resistance. Containers made of this material are often used in chemical industry, such as facial cleanser, salad, plastic bottle, cosmetic hose, etc.
 
5、PP
 
The Chinese name of polypropylene is No. 5 material on the international material identification number. It is a high-density material. The product processed with it is translucent, heat-resistant, impact resistant, acid and alkali resistant, but it has pores. Common uses of PP material processing: hot filled food, cooking utensils that can be used in microwave ovens, high-temperature food packaging, washbasins, mouthwash cups and other daily necessities for general household use.
 
6、PS
 
The Chinese name is polystyrene, which is No. 6 material in the international label material number. The product processed with it has high transparency, good sealing, but it is fragile and heat-resistant. It is often used in the processing of sealed cans and food boxes.
 
7、PC
 
It is made of No. 7 material in the international marking material number. The products processed with it are transparent, high heat resistance and not easy to be broken. It is commonly used in the processing of milk bottles, distillation barrels, heat-resistant barrels and medicine bottles. PC is the best plastic, but the price is the highest among the seven products.
