In the pharmaceutical industry, drug safety and efficacy are the lifeline. This depends not only on the composition and manufacturing process of the drug itself but also on the quality of its external "protective layer"—the pharmaceutical packaging material. Packaging materials come into direct contact with drugs, and their barrier properties, seal integrity, physical strength, and chemical stability directly impact the safety and effectiveness of the drug during storage, transportation, and even use.
