Drug packaging bags are usually made of plastic materials such as high-density polyethylene (HDPE) or polypropylene (PP). These materials have excellent moisture-proof, waterproof, dustproof, shockproof, corrosion-resistant and other characteristics, and are non-toxic, odorless and tasteless, meeting the strict requirements of drug packaging. The drug packaging bag will also print relevant information about the drug, such as the drug name, manufacturer, production date, usage method, etc., for the convenience of patients to use and carry. Drug packaging bags are generally cylindrical or rectangular, and different specifications and shapes can be selected according to different types and dosage forms of drugs. In addition to plastic materials, drug packaging bags can also be made of other materials such as paper and aluminum foil. The specific material used depends on the characteristics of the drug and packaging requirements.
