Polypropylene (PP) vial is a packaging solution for the manufacturing and storage of injectable drugs. PP is a thermoplastic polymer known for its high strength, durability, and resistance to a wide range of chemicals. These properties make it an ideal material for the production of vials that contain sensitive and potentially hazardous drugs. PP vials are also lightweight and have excellent dimensional stability, which allows for greater control and accuracy during the manufacturing process. In addition to their physical properties, PP vials offer several benefits for injectable drug manufacturing. One of the most significant advantages of PP vials is their compatibility with a range of sterilization methods, including autoclaving, gamma irradiation, and ethylene oxide (EtO) gas [1]. This versatility allows manufacturers to select the most appropriate sterilization method for their specific drug product, which can improve the safety and efficacy of the final product. PP vials also offer excellent sealing properties, which can help prevent contamination and maintain the sterility of the drug.
