Introduction of the test method for the sealing performance of tincture water plastic bottle

Abstract: in order to prevent the influence of light, heat, oxygen and other factors on the drug and ensure that the drug is not affected by moisture and deterioration within the validity period, the tincture water plastic bottle should have good sealing performance Relevant national standards have made clear provisions on this, which is also the key indicator of production enterprises Key words: tincture water plastic bottle sealing performance test, sealing, tincture water plastic bottle, sealing tester text: Tincture water plastic bottle is widely used in the packaging of oral solid drugs and oral liquid drugs because of its light weight, high strength, not easy to be damaged, good sealing performance, moisture-proof and sanitation, meeting the special requirements of drug packaging, and being able to be directly used in drug packaging without cleaning and drying In order to prevent the influence of light, heat, oxygen, etc on the drug and ensure that the drug is not affected by moisture and deterioration within the validity period, the tincture water plastic bottle should have good sealing performance Relevant national standards have made clear provisions on this, which is also the key indicator of production enterprises Next, Labthink blue light combined with mfy-01 sealing tester briefly introduces the sealing performance test of tincture water plastic bottle Sealing performance refers to the sealing reliability of tincture water agent plastic bottles, through which the integrity of the whole product packaging can be ensured In order to ensure that the medicine will not be affected with damp and deterioration within the validity period, the tincture water plastic bottle should have good sealing performance, which is clearly stipulated in the relevant national standards: take a certain number of tincture water plastic bottles, put a proper amount of glass balls into each bottle, and tighten the bottle cap (see the table below for the torque) Cover diameter (mm) torque (n · cm) 15 ~ 22 59 ~ 78 23 ~ 48 98 ~ 118 49 ~ 70 147 ~ 176 and then put it into a container with an air extraction device Immerse it in water, vacuumize it to a vacuum degree of 27kpa, maintain it for 2 minutes, and there shall be no water or bubbles in the bottle The mfy-01 sealing tester of Labthink blue light makes use of the vacuum principle to determine the sealing performance of the sample by vacuuming the vacuum chamber to produce the internal and external pressure difference of the sample immersed in water, observing the gas escaping from the sample, or by vacuuming the vacuum chamber to produce the internal and external pressure difference of the sample, observing the expansion of the sample and the recovery of the sample shape after the vacuum is released to determine the sample The sealing performance of In the process of experiment, only input the corresponding pressure value and time, the instrument can realize full-automatic test, convenient operation and friendly human-computer interaction The above method is based on the principle of visual inspection, which is a qualitative test method If you want to test the sealing and leakage performance of packaging quantitatively, you can use the positive pressure principle sealing performance test equipment, such as lssd-01 leakage and sealing strength tester of Labthink Languang Of course, after the sealing index of tincture water agent plastic bottle is qualified, other indexes such as oxygen resistance and moisture resistance need to be controlled to ensure the quality of products within the shelf life For more information about related testing instruments, you can log in to Languang to check the specific information Jinan Languang Electromechanical Technology Co., Ltd is willing to enhance exchanges and cooperation with enterprises and institutions in the industry.
