28/410 Dispenser Spray Pump Factory Introduces The Characteristics Of 7 Kinds Of Packaging Materials

28/410 Dispenser Spray Pump Factory introduces the characteristics of 7 packaging materials:

1. PET
It is the No. 1 material on the International Material Designation 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. Commonly used in packaging materials for food, beverage bottles, and cosmetic bottles. It is precise because of its high air tightness and no capillary pores in the packaging container that it is often used as a packaging container for alcohol.

2. HDPE
The Chinese name is high-density polyethylene, which is commonly known as high-density PE. It is the second material on the international material label number. Its main feature is good acid and alkali resistance. The products processed with it are translucent and have poor heat resistance. When used as packaging containers, there will be capillary pores. It is often used as a packaging container for chemicals such as pharmaceutical bottles and cosmetics.

3. PVC
The Chinese name is polyvinyl chloride, which is the No. 3 material on the international material label number. Its main characteristics are transparency and heat resistance. Before the advent of PET, it was often used as a packaging material for beverages such as mineral water and fruit juice. At present, the biggest application is to make water pipes and enameled outer wires for building materials. The container made of it will have pores, so it is not suitable for wine.

4. LDPE
The Chinese name is low-density polyethylene, also known as low-density PE. It is No. 4 material on the international material labeling 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 chemicals such as facial cleansers, salads, glue bottles, cosmetic hoses, etc.

5. PP
The Chinese name is polypropylene, which is the No. 5 material on the international material label number. It is a high-density material. The products processed from it are translucent, resistant to heat, impact, acid, and alkali, but have pores. . Commonly used PP material processing uses: hot-packed food, cooking tableware that can be used in microwave ovens, food packaging that can hold high temperature, general household washbasins, mouthwash cups, and other daily necessities.

6. PS
The Chinese name is polystyrene, which is the No. 6 material on the international label material number. The products processed with it are highly transparent and have good sealing performance, but are fragile and not heat-resistant. It is often used in the processing of sealed cans and food boxes.

7. PC
It is the No. 7 material on the international label material number, and the products processed with it are transparent, have high heat resistance, and are not easy to break. It is often used in the processing of milk bottles, distillation barrels, heat-resistant barrels and medicine bottles. PC is the best of plastics, but the price is the highest among the seven products.
