February 13, 2025 – CPP Films: A Rising Star in the Packaging Industry with Versatile Applications
Cast polypropylene (CPP) films, renowned for their exceptional clarity and uniform thickness, have emerged as a prominent player in the packaging sector. Produced through the cast extrusion process, these polypropylene films exhibit balanced properties in both machine and cross directions, making them an ideal choice as the inner layer material for laminated films, thus offering new options for packaging solutions.
The CPP film family is diverse, catering to various applications. It includes general-purpose CPP, aluminum-coated CPP, and retortable CPP, among others. General-purpose CPP films, with their moderate thickness, enhance transparency when laminated with OPP and offer a sturdy feel, making them perfect for gift packaging bags. On the other hand, retortable CPP films withstand high-temperature cooking, boast excellent oil resistance and gas barrier properties, and exhibit high heat-sealing strength, finding widespread use as the inner layer for meat packaging.
According to industry insights from the Color Masterbatch Industry Network, CPP films outshine other film types with their cost-effectiveness, higher productivity, superior stiffness, and outstanding barrier properties. Notably, CPP films excel in heat-sealing capabilities, performing even better at low temperatures, and demonstrate enhanced impact and tear resistance, positioning them as leaders in food packaging.
The applications of CPP films extend far beyond food packaging, encompassing textiles, flowers, daily necessities, industrial products, and more. As living standards improve and the consumer market expands, the demand for CPP films continues to grow. Particularly in food packaging, CPP films are widely used due to their excellent barrier properties, transparency, and heat resistance.
Reports indicate that the market capacity for cast polypropylene packaging films in China is on the rise, with steady growth projected for the coming years. To meet the diverse needs of customers, companies are intensifying their investment in technology research and development, refining production processes and formulas, and enhancing the performance indicators of CPP films. The development and application of these new products are further expanding the market space for CPP films, making them more competitive in future development.
