Test and test instrument for sealing performance of tablet plastic bottle packaging

Abstract: 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 tablet 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: tablet plastic bottle sealing performance test, sealing performance, tablet plastic bottle, sealing tester text: Tablet plastic bottles are widely used in the packaging of oral solid drugs and oral liquid drugs because of their light weight, high strength, not easy to be damaged, good sealing performance, moisture-proof and sanitation, meeting the special requirements of drug packaging and the advantages of being 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 tablet 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 introduced the sealing performance test of tablet plastic bottle Sealing performance refers to the sealing reliability of tablet plastic bottle, through which the integrity of the whole product packaging can be ensured In order to ensure that the drug does not get damp or go bad within the validity period, the tablet plastic bottle should have good sealing performance, which is clearly stipulated in relevant national standards: take a certain number of tablet 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 until the vacuum degree is 27kpa, and maintain it for 2 minutes There shall be no water or bubbles in the bottle Mfy-01 sealing tester of Labthink blue light According to the principle of vacuum, by vacuuming the vacuum chamber, the sample immersed in water will generate internal and external pressure difference, and the gas escaping situation in the sample will be observed to determine the sealing performance of the sample; or by vacuuming the vacuum chamber, the sample will generate internal and external pressure difference, and the sample shape recovery situation after expansion and vacuum release will be observed to determine the sealing performance of the sample 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 ensuring that the sealing index of the tablet plastic bottle is qualified, it is necessary to control other indexes such as oxygen resistance and moisture resistance, so as 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.
