Medicinal plastic bottles come in a wide variety of specifications, ranging from small volumes of just a few milliliters to large capacities of thousands of milliliters. They can be transparent, colored, or have various shapes, making them highly versatile for different pharmaceutical applications. With such a competitive market, drug manufacturers must carefully evaluate several key factors when selecting the right plastic bottles for their products. First, the selection of primary raw materials and additive formulas is crucial. Different types of plastic bottles are manufactured according to specific product standards, and the main materials must meet strict requirements such as being non-toxic, odorless, and safe for pharmaceutical use. For example, high-density polyethylene (HDPE) and polypropylene (PP) are commonly used for solid dosage forms like tablets, while polyethylene terephthalate (PET) is preferred for transparent containers. When higher barrier properties are needed, especially for light-sensitive or moisture-sensitive drugs, materials like polyethylene naphthalate (PEN) may be used instead. Second, the sealing performance and water vapor permeability of the bottle body and cap are essential factors that affect the stability of the drug. A strong seal ensures that the contents remain protected from external contaminants and moisture, which is vital for maintaining the integrity of the medication over time. Third, adherence to product quality standards is a critical consideration. Manufacturers should not only follow national and industry regulations but also establish internal corporate standards that are even more rigorous. This helps ensure consistent quality and reliability in the final product. Fourth, a robust quality assurance system is necessary. Auditing suppliers plays an important role in the procurement process, allowing companies to assess the production facilities, technical capabilities, and overall quality control measures of potential vendors. This ensures that the chosen suppliers are capable of delivering high-quality, compliant products consistently. Finally, the stability and compatibility of the drug with the plastic container must be thoroughly tested, especially when using new materials or innovative manufacturing processes. Compatibility tests should include assessments of drug penetration, dissolution, adsorption, chemical interactions, and denaturation. These evaluations help ensure that the plastic bottle does not compromise the safety or efficacy of the drug.
