1. What main materials and auxiliary formulations are selected for plastic bottles has a crucial impact on their quality and high bottom. There are many kinds of main materials in the selection, which requires us to investigate its induction function in the selection, usually the tablet selection of high-density polyethylene, polypropylene bottles, such as the demand for transparency can be used PET bottles, such as drug demand isolation function is higher, and light blocking, opaque, then choose brown PET bottles, isolation function is better for PEN bottles. Medicinal liquid bottles are usually polypropylene bottles or polyester bottles as the main material.
2, sealing, penetration: sealing and water vapor penetration are two important technical indicators of pharmaceutical plastic bottles, they play an important impact on the stability of the charge.
3, stability and compatibility: the selection of plastic bottles, especially the selection of new plastic bottles (or new raw materials, new processes) for new drugs is probably leading the loading experiment to investigate the stability of the charge and the compatibility between plastic bottles and drugs. The penetration, dissolution, adsorption, chemical reaction and denaturation of raw materials between drugs and plastic bottles are necessary to be determined by scientific testing.
4, product quality and assurance system: pharmaceutical plastic bottle manufacturers probably have the corresponding national and industry standards. Together with the manufacturer's software and hardware equipment, skill equipment, quality induction level to make all the correct evaluation.
