CPP OPP Packaging

CPP OPP packaging is a term that combines two different packaging materials: CPP (Cast Polypropylene) and OPP (Oriented Polypropylene). These materials are commonly used in the packaging industry, each offering distinct characteristics and advantages.CPP (Cast Polypropylene) is a type of flexible plastic film that is typically used as the inner layer of packaging. It is produced using the cast film extrusion process, resulting in a film with good clarity, strength, and flexibility. CPP films provide excellent moisture and oxygen barrier properties, making them suitable for packaging perishable goods such as food and pharmaceutical products. They also offer high heat sealability, allowing for secure sealing of packages.OPP (Oriented Polypropylene) is a thermoplastic film that undergoes a biaxial orientation process, which aligns the molecular structure of the film and enhances its mechanical properties. OPP films are known for their high tensile strength, puncture resistance, and dimensional stability. They can be produced in different thicknesses, offering varying levels of transparency or opacity. OPP films also have good printability, enabling high-quality graphics and branding on the packaging.When CPP and OPP films are used together in packaging, CPP is often used as the inner layer for its moisture barrier properties, while OPP is used as the outer layer for its strength and printability. This combination provides a packaging solution that offers protection, visibility of the product, and attractive branding options.Overall, CPP OPP packaging provides a versatile and reliable packaging solution that combines the advantages of both CPP and OPP films, ensuring the integrity and visual appeal of the packaged products.
