How to test the sealing performance of tablet plastic bottle packaging? With what equipment?

by admin

tablet plastic bottles are widely used in the packaging of oral solid drugs and oral liquid drugs because they have the advantages of light weight, high strength, not easy to be damaged, good sealing performance, moisture-proof and hygiene, meet the special requirements of drug packaging, and can be directly used in drug packaging without cleaning and drying. In order to prevent the influence of light, heat and oxygen 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. Relevant national standards have made clear provisions on this, which is also the key index of production enterprises. Next, Jinan Mingwei Testing Technology Co., Ltd. briefly introduces the sealing performance test of tablet plastic bottles combined with mfy-01 sealing tester. Sealing performance refers to the reliability of the sealing of tablet plastic bottles. Through this test, the integrity of the sealing of the whole product package can be ensured. In order to ensure that the drugs will not be affected by moisture and deterioration within the validity period, the tablet plastic bottles should have good sealing, which is clearly stipulated in relevant national standards: take a certain number of tablet plastic bottles, put an appropriate amount of glass balls in each bottle, and tighten the bottle cap (see the following table for torque). Cover diameter (mm) torque (n ยท cm) 15 ~ 22 59 ~ 78 23 ~ 48 98 ~ 118 49 ~ 70 147 ~ 176, then put it into a container with air extraction device, immerse it with water, vacuum it to a vacuum degree of 27kpa, and maintain it for 2 minutes. There shall be no water or bubbles in the bottle. Mfy-01 sealing tester of Jinan Mingwei Testing Technology Co., Ltd. (0531-88808020) uses the vacuum principle to make the sample immersed in water produce internal and external pressure difference by vacuumizing the vacuum chamber, and observe the gas escape in the sample to determine the sealing performance of the sample; or make the sample produce internal and external pressure difference by vacuumizing the vacuum chamber, Observe the shape recovery of the sample after expansion and vacuum release to determine the sealing performance of the sample. In the experimental process, the instrument can realize full-automatic test only by inputting the corresponding pressure value and time, which is convenient to operate and friendly to human-computer interaction

hope to adopt

now there are sealing detection equipment based on thermal imaging principle, which can online non-contact detect the sealing quality problems caused by no aluminum foil, damaged aluminum foil and excessive 1315 or insufficient 3216 heat of the sealing machine . eight hundred and seventy-five
