On the quality of non PVC soft bag infusion welding

Key words: non PVC soft packaging infusion bag and interface welding quality inspection, non PVC film, interface welding, leakage, leakage and sealing strength tester with the rapid development of China's economy and the improvement of people's medical level, the use of non PVC multi-layer co extrusion film soft bag infusion is increasing, the requirements for improving the quality of infusion and ensuring the safety and effectiveness of patient infusion are also increasing Therefore, it is urgent to improve the packaging container, the key factor affecting the quality of infusion Among them, the leakage of non PVC soft film and Polypropylene Interface welding is always difficult to overcome Based on years of research experience, combined with intelligent electronic tensile testing machine, leakage and sealing strength tester, Labthink makes the following brief introduction to the quality inspection of non PVC soft packaging infusion bag and interface welding 1、 Test of welding strength (heat sealing strength) between infusion film and interface of non PVC flexible packaging the test of heat sealing strength of infusion film and interface of non PVC flexible packaging is carried out by heating a certain welding die The XLW series intelligent electronic tensile testing machine produced by Labthink blue light can be used to test the welding strength of non PVC infusion soft film and interface During the test and detection, the special customized fixture is used to clamp the membrane material at one side and the interface at the other side, and directly click the "heat sealing strength" test item on the tensile machine to complete the test 2、 The welding strength (sealing strength) of non PVC soft package infusion bag and interface is generally inverted during infusion treatment, so the infusion film and interface will bear certain pressure, which requires that there should be no leakage at the interface welding Lssd-01 leakage and sealing strength tester produced by Labthink Languang adopts the positive pressure test principle to inflate and pressurize the infusion soft bag The air pressure is equal to the pressure of liquid medicine Put the sample into the professional container (containing) to check the leakage In addition, the leakage and sealing strength tester can also be used for the pressure breaking performance of infusion soft bags, equipped with a professional constraint plate experimental device to complete the test The above is a brief summary of the welding detection methods of non PVC soft packaging infusion bag and interface of Jinan Languang Electromechanical Technology Co., Ltd Of course, after ensuring these indicators, other indicators need to be controlled, such as the barrier performance of the infusion bag packaging for oxygen, water vapor and nitrogen, the heat sealing strength of the edge of the infusion bag packaging, etc For more information about related testing instruments, check the specific information or call Jinan Languang directly Jinan Languang Electromechanical Technology Co., Ltd is willing to enhance exchanges and cooperation with enterprises and institutions in the industry
