The selection of raw materials for solid pharmaceutical plastic bottles has been tested and approved by the quality certification body of the relevant packaging and production department; At present, in terms of materials, plastic bottles are mainly made of plastic. The outstanding feature of the plastic bottles is that they are light in weight and are not afraid of falling. Therefore, plastic bottles are widely used in various fields by virtue of their competitive advantages.
Sealability and water vapor permeability of solid medical plastic bottle body and lid. Sealing property and water vapor permeability are two important technical indicators of liquid plastic bottles, which play an important role in the stability of packaged products. Quality standard for liquid plastic bottle. The quality of products can be analyzed and judged from the product quality standards of the manufacturer. The injection and blow molding of solid pharmaceutical plastic bottles requires two kinds of molds: parison mold and blow molding mold, and the mold requirements are high, so the cost of injection and blow molding mold is high, about 2-3 times that of extrusion and blow molding. Most of the bottles formed by injection blow molding are of small volume (generally 10-300 mL), and products with complex shapes cannot be formed, so the energy consumption is significantly higher.
If we need high transparency packaging bottles, choose polyester plastic bottles, and if it is some drugs that do not need to see light, choose brown plastic bottles. There are many kinds of materials to choose from. No matter what kind of material is selected, the medical plastic bottle plays an important role in the packaged goods. The size and cap of medical plastic bottle are required, and the cap should be made of pp material. Generally, plastic bottles made of tablet materials are usually made of high-density polyethylene. Generally, polypropylene or polyester bottles are used as the main materials for liquid dosage forms. The infiltration and secretion of water vapor and the tightness of the bottle are important indicators of plastic bottles. Whether they are qualified or not is related to the quality and safety of drugs.
Therefore, the use specifications of medical plastic bottles are relatively strict in medicine. Not every kind of plastic bottle is suitable for packaging drugs. We can understand and distinguish the raw materials and auxiliary ingredients of medical plastic bottles, so as to know whether the materials of plastic bottles are harmful to human health. This conclusion also meets our original intention of purchasing.
Now in drug packaging, the sealing degree of the solid pharmaceutical plastic bottle mouth will directly affect the drug safety within the drug validity period. The injection blow molding method is conducive to ensuring the size accuracy of the bottle mouth and thread and the appearance size accuracy. The wall thickness of the bottle is uniform, which meets the drug packaging requirements and can prevent the drugs in the bottle from being polluted by external substances, Therefore, the relevant drug supervision bureau proposed to use the injection blow molding method to produce high-quality solid pharmaceutical plastic bottles.
