The packaging materials of drugs can be simply understood as the packaging materials and containers that directly come into contact with drugs. The main function of medicine wrapper material is to preserve the medicinal properties of drugs and make them more convenient for transportation and use. The improper use of medicine wrapper material may absorb the medicinal properties of the drugs or chemically react with them, causing the drugs to become ineffective and endangering people's health.  Therefore, the selection of medicine packing material must be in accordance with national standards to ensure that the quality of drugs is not affected. Common medicine packing materials are chosen according to the medicinal properties of drugs.

Characteristics of plastic medicine wrapper material and its impact on drug quality

Characteristics of plastic medicine wrapper material

Plastic medicine packing materials are relatively light, have good plasticity, and are convenient for transportation. They do not need to introduce air during the infusion process, but their sealing properties are not as good as glass containers. At present, plastic medicine packing materials have gradually replaced glass bottles in the field of infusion containers because they do not require complex process pretreatment, which is conducive to improving production efficiency, and are also very convenient for storage and transportation.

The impact of the plastic medicine wrapper material on drug quality

The commonly used plastic medical packaging materials include polyethylene, polypropylene, and polyvinyl chloride, with more use of polyvinyl chloride, which has poor heat resistance and needs to be added with heat stabilizers, which can transfer to drugs and affect drug quality. Moreover, the plasticizer, which is the highest content in plastics, can easily enter the human body through infusion and harm people's health. Some plastic medicine packing materials can also adsorb drugs and reduce their efficacy.

Characteristics of metal medicine packing materials and their impact on drug quality

Characteristics of metal medicine packing materials

Aluminum is the most commonly used medical metal medicine wrapper material. It does not rust, is easy to use, has a beautiful appearance, and has excellent properties such as non-magnetism and non-toxicity of oxides. Aluminum is mainly used for aluminum caps of some powder formulations, but the cost of aluminum is relatively high, and its corrosion resistance is poor.

The impact of the metal medicine packing material on drug quality

Although the stability of metal medicine wrapper material is extremely high, they may still affect the medicinal properties of drugs. Studies have shown that the liquid in the ipratropium bromide aerosol can react with the aerosol valve to produce four impurities, which may have hidden harm to people's health.

Drugs are fundamental to treating diseases, and the quality of drugs is closely related to people's health. Quality problems may limit the therapeutic effect of drugs, and some may even have incalculable effects on people's lives. Pharma packaging material has a great impact on the quality of drugs, so when selecting packaging materials, it must be strictly selected according to the characteristics of drugs to ensure that their medicinal properties can be best preserved.
