Pharmaceutical packaging With the advancement of science and technology, packaging is constantly innovating, with more different products appearing, and reagent bottles are constantly being updated. What is the main material of reagent bottles now?
At present, reagent bottles are divided into glass bottles and plastic bottles. According to the size, they can be divided into wide-mouth bottles and narrow-mouth bottles. According to the contents, they can be divided into solid and liquid reagent bottles. Wide-mouth bottles contain solids and narrow-neck bottles contain liquids. . The inside of the bottle mouth is frosted design to keep it sealed to prevent leakage of reagents.
Nowadays, plastic bottles are being used more and more, gradually replacing glass bottles. The material of plastic bottles is made of high-permeability polypropylene. The properties of polypropylene are non-toxic, odorless, low density, excellent in strength, rigidity, hardness and heat resistance. For low pressure polyethylene, it can be used at around 100℃. It has good dielectric properties and high-frequency insulation and is not affected by humidity, but it becomes brittle at low temperatures, not wear-resistant, and easy to age. Common organic solvents such as acids and alkalis have little effect on it.
Polypropylene reagent bottles are favored by manufacturers due to their excellent performance, and will develop better in the market. Plastic reagent bottles will become the mainstream in the future and become an indispensable type of pharmaceutical packaging.
