1. Selection of medical plastic bottle formula: the product standard of solid plastic bottle specifies the applicable main raw materials, and must meet the requirements of non-toxic and no odor. As there are many kinds of main raw materials available, it is necessary to select the comprehensive properties of the raw materials.

High-density polyethylene (HDPE) and polypropylene（PP） bottle are used for solid capsules and oral tablets.

HDPE Bottles

Polypropylene(PP) bottle or polyester(PET) bottle is generally selected as the main raw material for liquid dosage form drugs. If transparency is needed, PET bottles can be used. If drugs need higher barrier performance, light blocking, and opacity, brown PET bottles can be used.

2. Quality standard of the plastic bottle. The quality of products can be analyzed and judged by the product quality standards of the manufacturer. The enterprise standard of Tianjin Foerhao Packaging Co., Ltd. is stricter than the national standard and industry standard.

3. Sealing and water vapor permeability of bottle and cap. Sealing property and water vapor permeability are two important technical indexes of medical plastic bottles, which play an important role in the charge stability.

4. Quality assurance system. Audit of suppliers has become an essential part of purchasing plastic bottles. Through the audit, the comprehensive level of software and hardware facilities, technical equipment, and quality can be comprehensively and correctly evaluated.

5. The charge stability and compatibility of the plastic bottle. When selecting plastic bottles, especially new plastic bottles (or new materials and new technologies) for new drugs, the charging test should be carried out to investigate the charging stability and the compatibility between plastic bottles and drugs. The penetration, dissolution, adsorption, chemical reaction, and denaturation of drugs and plastic bottle materials must be determined by scientific testing. Our experimental data have been submitted to the FDA for filing.
