What is the difference between oral liquid bottles and drug glass tubes

Nowadays, oral liquid bottles are made of more sodium and calcium. Controlled drug bottles are mostly used in medical treatment, and their wall thickness is relatively thin. Many people are not quite clear about the difference between oral liquid bottles and oral liquid bottles made of control, and at the time of selection, it is not clear which one should be selected. The network shows how to choose oral liquid bottles is appropriate for their own.


As we all know, oral liquid glass bottles are widely used in daily life, but sodium calcium glass can be turned into oral liquid bottles after metal surface treatment. At first, the coating of glass bottles is carried out after bottle forming and before quenching. When the glass bottle is slowly cooled to 500~600 degrees, the metal material coating agent is sprayed on the surface of the vessel to produce a certain thickness of the original film, which improves the surface compressive strength by about 30%.

The stopper of oral liquid bottle is anti-theft spiral mouth, which can be equipped with aluminum cap, all kinds of plastic cap, aluminum cap, butyl gasket and PE gasket. Oral liquid bottles can also be used to hold health products. There are small mouthfuls for drinking. Oral liquid bottles made by molds have a relatively large volume, which can exceed 500ml completely.

Although the compression strength of oral liquid bottle made by mold is higher than that of controlled oral liquid bottle, the wall of controlled oral liquid bottle is smoother than that of molded oral liquid bottle, and the wall of oral liquid bottle made by mold is more prone to bubbles and cracks. The reasons for bubbles in oral liquid bottles made from mold production are: the laminated glass material liquid in industrial furnaces is not tidy or the material temperature is not symmetrical, which will also make the production rate of bubbles, small particles and small hemp blanks in glass bottles. Or when the laminated glass material falls into the initial mold, it can not be accurately entered into the initial mold. The friction with the mold wall is too large, resulting in folds. After the positive air blowing inspection, the folds spread out and become larger, resulting in folds in the glass bottle body.
