What are the commonly used pharmaceutical packaging materials? I believe many friends are interested in learning about them. Here, the editor has organized some relevant content about commonly used pharmaceutical packaging materials, hoping to be helpful to everyone.

① Glass: Glass has the advantages of moisture resistance, easy sealing, transparency, and relatively stable chemical properties, but it also has many disadvantages, such as being heavy, fragile, and releasing alkaline substances and insoluble tablets due to water solution erosion. In order to ensure the quality of drugs, the Pharmacopoeia stipulates that ampoules and large infusion bottles must use hard neutral glass. When storing drugs that are prone to spoilage when exposed to light, containers made of brown glass should be used.

② Plastic: Plastic has advantages such as strong packaging, easy sealing, bright color, transparency and aesthetics, light weight, convenient carrying, and low price. However, due to the frequent addition of additives such as plasticizers and stabilizers in production, these additives may come into direct contact with drugs, undergo chemical reactions with drugs, and cause changes in drug quality. Plastic also has disadvantages such as breathability, transparency, and easy adsorption, These shortcomings will accelerate the rate of drug oxidation and deterioration, causing drug deterioration.

③ Paper products: Paper products come from a wide range of sources and have low costs. After being coated with moisture-proof paint, they have certain moisture-proof properties. The packaging volume can be manufactured according to demand, and they have recycling value. They are one of the most widely used packaging materials today, but their disadvantages are low strength and easy deformation.

④ Metal: Commonly used include black iron sheet, galvanized iron sheet, tinplate, aluminum foil, etc. These types of packaging have good pressure resistance, sealing performance, and high cost.

Wood: It has compressive strength and is a commonly used packaging material. Due to the consumption of forest resources, it has gradually been replaced by materials such as paper and plastic.

Composite materials: Composite materials are the emerging trend in packaging materials. They are packaging materials composed of multiple layers of plastic, paper, aluminum foil, etc. Commonly used include paper plastic composite materials, aluminum foil polyethylene composite materials, aluminum foil polyester ethylene, etc. These composite materials have good mechanical strength, biological corrosion resistance, vacuum maintenance performance, and compressive performance.

Rubber products: mainly used for various bottle stoppers of bottled drugs. Due to direct contact with drugs, it is required to have very good biochemical stability and excellent sealing to ensure that the entry of air and water does not deteriorate within the validity period.

From the perspective of development trends, packaging materials are moving towards replacing wood with paper, replacing paper with plastic, or forming various composite materials with paper, plastic, and aluminum foil. The application of special packaging materials such as polytetrafluoroethylene, silicone resin, polyester composite board, or foam polyurethane is on the rise.
