The development of CPP production scale and extrusion equipment has led to an increasing use of raw materials and an optional range, which has led to the development of special materials for casting, which are more refined, specialized and higher performance. Various special materials with more precise division of labor are constantly emerging, and each material plays its own role at different levels, giving the film new performance to adapt to different market demands. At the same time, the production of high-performance raw materials for the special requirements of users is also emerging, which will bring greater profits to resin producers. At present, the special material development hotspot is low temperature heat sealing material, and the industrialized production of butene/propylene random copolymer is a newly launched product in the market.

In recent years, with the strengthening of the consumer market, the application field of CPP has been expanding and its development has been accelerated. So far, there are more than 30 CPP manufacturers in the country, with more than 40 production lines, with a total production capacity of 150,000 to 170,000 tons/year. However, the dependence of the special materials for cast film on imported materials is more serious than that of BOPP film and blown film. At present, the annual import volume accounts for about 60% of the total usage. The domestic CPP special materials are relatively single, only produced by Shanghai Petrochemical Corporation and Beijing Yanshan Petrochemical Company. They are generally used for composite film heat seal layer, semi-cooked film, and high-temperature cooking film resin for aluminized film are lacking. At the same time, the similarities in the products of domestic enterprises are more serious. The equipment production capacity of similar low- and mid-range products is higher than the increase in demand, and the market is relatively weak, which inhibits the expansion of film production and the rise in prices.
Now, CPP has become an indispensable product in the packaging industry. Manufacturers use new equipment and new materials to continuously expand production scale, increase production efficiency, increase product categories, and expand new application areas. It can be expected that with the improvement of China's economic level and consumption level, its production development will be further expanded. At the same time, it should be noted that there are still some or all of the cast film depending on the import situation. How to accelerate the localization is also a major problem that the plastic processing and resin production industries need to solve as soon as possible.
