Polypropylene (PP), as one of the five general plastics, is widely used in daily life.

Polypropylene is a plastic raw material with minimal density, and its appearance is colorless and translucent particles. As a food grade plastic, it is widely used in food packaging, such as foam plastic boxes, PP plastic cups, and so on. Polypropylene can be divided into five categories according to its main uses: PP injection molding, PP drawing, PP fiber, PP film, and PP pipe.

1. PP injection molding:

PP injection plastic is mainly used in small household appliances, toys, washing machines, auto parts, etc.

In recent years, the improvement of people's living standards and the implementation of China's second tire have led to a gradual increase in the demand for polypropylene injection molding in the downstream. Different injection molding varieties also have differences in their demand in the low and high seasons. For example, the demand for injection molding pots and barrels is relatively strong in the school season, while the demand for accessories and gifts is booming due to the impact of many festivals. In general, PP injection molding is relatively frequently used.

2. PP wire drawing:

Polypropylene wire drawing is mainly used in plastic woven products. The daily use of container bags, woven bags, food bags and transparent bags are all PP wire drawing products.

Since the implementation of domestic environmental protection in 2017, the demand for packaging of cement and building materials has been declining, and the plastic weaving industry has been greatly impacted. Accordingly, the PP plastic weaving market is under pressure. In the future, the proportion of PP plastic weaving in the overall use of polypropylene will continue to decline, and the plastic weaving industry will gradually expand into large packaging bags with high capacity, high quality or small packaging bags with low capacity and low content.

3. PP film:

Polypropylene film is generally divided into BOPP film, CPP film and IPP film. PP film is mainly used for food packaging.

Compared with PE packaging bags, PP film food packaging bags have better transparency, greater hardness and more high-end appearance. Downstream demand is mainly concentrated around festivals and holidays.

4. PP fiber:

Polypropylene fiber is a kind of fiber product made from polypropylene by melt spinning. It is mainly used in decoration, clothing and other fields. Since the implementation of the second child in 2011, the downstream wet wipes, diapers and other maternal and infant supplies have increased sharply, and the domestic fiber material has been in short supply.

According to data statistics, the global demand for fiber will continue to grow significantly, and the composite annual growth rate is expected to be 2.6% from 2017 to 2025. Therefore, the downstream demand for PP fiber will continue to grow in the later period.

5. PP pipe:

PP pipe material is mainly used in water supply and heating systems due to its non-toxic and high-temperature resistant properties. Compared with PE pipe material, PP pipe material has light weight, convenient transportation, good environmental protection performance and can be recycled.
