The demand for plastic film in the domestic market is expected to grow steadily, with experts forecasting a 9% annual increase over the next few years. This growth reflects the strong and expanding market potential for plastic films in China. A significant portion of the country's plastic film consumption—approximately two-thirds—is used for packaging applications, making it one of the most important sectors for this material. Another 30% is dedicated to agricultural plastic films, which play a crucial role in modern farming practices. The remaining 10% is utilized across various industries, including electrical insulation, photographic materials, and electronic information products.
China is the world leader in both the production and application of agricultural plastic films. The country has a substantial manufacturing capacity, with an annual output of around 900,000 tons of biaxially oriented polypropylene (BOPP) film. Within this sector, the majority of the produced films are standard light films, accounting for about 75% of total output. Only 10% of the BOPP films are smoke films, while pearl films make up approximately 7%. Electrical films represent a smaller share at 3%, and other specialized films account for the remaining 5%.
With the increasing demand from multiple industries, the plastic film sector in China continues to evolve, driven by technological advancements and the need for more efficient and sustainable materials. As the market expands, companies are focusing on innovation and diversification to meet the growing needs of consumers and businesses alike.

There are two main types of fountain pumps: centrifugal pumps and submersible pumps. Centrifugal pumps are suitable for fountain designs that require uniform head, while submersible pumps are suitable for fountain designs that require flexible adjustment of head. Submersible pumps are superior to centrifugal pumps in terms of flexibility, but centrifugal pumps perform better in terms of performance, efficiency, and maintenance rate. When choosing a fountain pump, you need to consider the following points:
Flow and head: According to the scale and design requirements of the fountain, choose the appropriate pump flow and head to ensure that the pump can provide sufficient water volume and pressure.
Power and efficiency: Choose an energy-efficient pump to reduce operating costs.
Material and durability: Choose a pump made of corrosion-resistant and rust-proof materials to ensure long-term stable operation.
Noise level: Choose a pump with lower noise to avoid interference with the surrounding environment and spectators.
