What is the air tightness of medicinal plastic bottles

From production to packaging, medicinal glass bottles are automatically completed by machines. The editor of cream jars manufacturers introduced that medicinal glass bottles are produced in a purification workshop of 100,000 grades. When workers are in the workshop, they must carry out the process. Due to the strict requirements of changing clothing, medicinal glass bottles have undergone secondary inspection during the production process. The glass bottles produced have the advantages of very smooth bottle walls, no impurities and no bubbles.

What is the air tightness of medicinal plastic bottles? Simply speaking, it is tested according to relevant national standards. For example, the reliability of the sealing of chocolate food plastic bottles is carried out by taking a certain number of chocolate plastic bottles, putting an appropriate amount of glass balls in each bottle, and tightening the bottle cap. Then put it into a container with an air extraction device, immerse it in water, and evacuate it to a vacuum of 27kpa for 2 minutes. There should be no water or bubbles in the bottle. Of course, to ensure the airtightness of the plastic bottle of chocolate through the index, some other economic indicators are also needed, such as resistance to moisture, oxygen resistance and control to ensure the quality of food plastic bottle products.

Of course, there is also a more scientific test equipment for testing the air tightness of food plastic bottles.

Now there are also machines on the market that introduce a seal tester, which uses the principle of a vacuum cleaner to make a vacuum in the chamber to make a sample of food plastic bottles submerged in water to produce the pressure difference between the inside and outside of the sample, and observe the gas escape inside the sample to determine the seal performance: Or through the vacuum chamber of the vacuum, the pressure difference between the inside and outside of the sample production, observe the inflation of the sample and the recovery of the shape of the sample after releasing the vacuum, in order to determine the sealing performance.

 The air-tightness of medicinal plastic bottles is very important for the medicine to be free from moisture and deterioration during the validity period, and it is also an important medium to prevent the influence of light, heat, oxygen, etc. on the medicine. Therefore, as a pharmaceutical plastic bottle manufacturer, we must pay attention to its air tightness testing.
