CPP&OPP Bag

CPP (Cast Polypropylene) and OPP (Oriented Polypropylene) bags are two different types of polypropylene used to meet various packaging needs, each with its own unique properties.

CPP bags are made from cast polypropylene film. This type of film has a liquid crystal structure, offering transparency, high flexibility, and durability. One of the most prominent features of CPP bags is their excellent sealing and durability. The film is known for its low moisture permeability and high tensile strength, which protects the contents of the bag from external factors. CPP bags are commonly used for packaging food products, pharmaceuticals, and other sensitive items because they meet high hygiene standards and help keep the products fresh. Additionally, CPP bags have good stretch capacity and can be securely closed with various sealing methods.

OPP bags are made from oriented polypropylene film and typically go through a two-stage production process: first, the film is stretched, and then the orientation process imparts the desired mechanical properties. This process ensures that OPP bags offer high durability, excellent transparency, and good print quality. OPP bags are often preferred for labeling and brand promotion because when printed, the colors are vibrant, and the details are sharp and clear. These bags are commonly used for packaging food, retail, and various consumer products.

Both types of bags have a wide range of applications in the packaging industry. CPP bags are an excellent choice for protecting products and are commonly used in applications requiring durability and flexibility, while OPP bags are preferred for enhancing aesthetics and brand visibility. Both film types offer different advantages in the packaging process and are chosen based on specific needs.
