CPP plastic refers to Co polymer of polypropylene plastic. Polypropylene copolymer is a thermoplastic material that is formed by copolymerization of propylene and other monomers such as ethylene or butene. It has many advantages, such as good impact resistance, excellent weather resistance, low permeability, high strength, and toughness. CPP plastic is often used in fields such as food packaging, medical devices, household goods, and clothing. It is widely used in bags, films, bottles, containers, boxes and other products because of its excellent plasticity and transparency, which can effectively protect the quality and freshness of food and other items. CPP plastic also has good chemical resistance and can resist the erosion of many chemicals. In addition, it also has excellent heat sealing performance, which can conveniently seal the packaging and maintain the integrity and safety of the items inside the packaging. In summary, CPP plastic is a commonly used thermoplastic with excellent physical and chemical properties, widely used in various fields of packaging and product production.
