Commonly used materials for medicinal plastic bottles

Pharmaceutical plastic bottles are packaging containers formed by blow molding. They have the advantages of not being damaged easily, good sealing performance, moisture-proof, and hygienic. The commonly used raw materials include polyethylene, polypropylene, and polyester. Different raw materials have different characteristics. .

Polyethylene: non-toxic, odorless, waxy to the touch, excellent low-temperature performance (the lowest operating temperature can reach -70-100 ° C), corrosion resistance to most acids and alkalis (not resistant to acids with oxidative properties), flexibility Well, it is not easy to break when dropped. Small water absorption, excellent electrical insulation. This kind of raw material is a type that is widely used in medical plastic bottles.

Polypropylene: Polypropylene feels harder than PE, but it has poor flexibility and high temperature resistance. The operating temperature range is -30~140°C. Solvent corrosion, can decompose under high temperature and oxidation.

PET oral liquid bottle

Polyester: High transparency, impact resistance, oil resistance, dilute acid resistance, and most solvent resistance, but it is afraid of high temperature. If it is packed in a packaging bag and exposed to the sun, it will be deformed, so pay attention to the transportation of polyester bottles, and be careful not to use cartons. show. Some candy tablets, calcium tablets, and oral liquids will choose transparent polyester bottles.

Taken together, polyethylene, polypropylene, and polyester are the three most commonly used raw materials for pharmaceutical plastic bottles. Each of the three has its own characteristics. When selecting packaging materials, it should be determined in combination with the characteristics of the drug's dosage form and storage requirements.
