A tablet refers to a tablet or special-shaped tablet made of medicinal powder or medicinal extract plus medicinal powder or auxiliary materials. Tablet medicine bottles are commonly used packaging for such drugs. Common raw materials include polyethylene (PE), polypropylene (PP), polyester (PET), etc. With so many materials, which material has better performance?
The performance of tablet medicine bottles of different materials is also different. These materials are all non-toxic and tasteless, and can withstand the corrosion of most acid, alkali and solvents. The difference is that polyethylene has excellent low-temperature properties (the lowest use temperature can reach -70-100 ℃), and good flexibility. Polypropylene has good gloss, high temperature resistance, and has a higher density than PE, but it is fragile at low temperatures. Polyester raw materials have high transparency and high impact strength, but they are not resistant to high temperatures. If they are packed in a packaging bag in the sun, they will be deformed.
Several commonly used plastic materials have different characteristics. Which material has better performance cannot be generalized. It needs to be determined according to the characteristics and specific needs of the drug. If terminal sterilization is required, polypropylene material can be selected. If flexibility is required, polyethylene material can be selected. If the transparency of the bottle body is required, polyester material can be selected.
In summary, the material properties of the tablet medicine bottle have their own advantages and disadvantages. Choosing the appropriate material for packaging according to the characteristics of the drug is a good choice to ensure the stability of the drug.
