Huadun East China helped YangziPetrochemical successfully develop new products of ternary CPP (copolymerized polypropylene casting film material), It has filled the production gap in East China and succeeded in replacing imports. Up to now, the sales of nearly 2000 tons have been completed.

ternary CPP has good transparency and low temperature, and is widely used in the hot sealing layer of packaging film such as food. In the process of "sweeping the market", Huadong East China learned that China's ternary CPP demand is strong, but the supply of domestic raw materials is insufficient, and it relies heavily on imports, especially in East China, there is no ternary CPP producer. Affected by the normalization of epidemic prevention and control, the supply of imported raw materials is unstable.

In order to ensure customers' production under the epidemic, Huadong gave full play to the advantages of integration of production, marketing, research and application, cooperated with the research institute of Yangzi Petrochemical to determine the product direction, formulated trial production plans, coordinated and arranged two trial production in just 3 months, and finally produced high-quality products, and coordinated all parties to open "green channel" to ship products. On the second day, Yangzi Petrochemical Research Institute and Yangzi Petrochemical Plastics Factory went to the customer's factory for on-site test materials. The customer said that the product quality is comparable to Korean imported materials and domestic ace materials, and the performance indicators fully meet the demand.
