Test method for sealing leakage and strength of medical aluminum plastic composite film packaging

Abstract: aluminum plastic composite film is divided into aluminum plastic film and aluminum plating composite film It has the advantages of good flexibility, moisture-proof, oxygen proof, light shielding, shielding, antistatic and other materials, and is widely used in food, medicine, chemical industry and other industries Especially in the field of medicine, the requirements for aluminum-plastic composite film packaging are more stringent, generally from the inside to the outside at least three layers It is very important to test the sealing and leakage performance of the packaging bag of aluminum-plastic composite film in the production process From the perspective of special test, taking lssd-01 leakage and sealing strength tester as an example, this paper introduces its scientific test method, test principle, equipment parameters, etc., hoping to provide some valuable reference for pharmaceutical packaging industry Key words: aluminum plastic composite film, medical aluminum plastic composite film, side leakage tester, sealing leakage performance, bursting pressure, breaking strength, sealing strength, sealing strength tester test samples: commonly used aluminum plastic composite film packaging bags in the pharmaceutical field (Note: provided by the customer of Jinan Saicheng instrument) Executive Standards: YBB 00252005, ybb-0016-2005 Testing equipment: the text of "lssd-01 leakage and sealing strength tester" independently developed by Jinan Saicheng: in the process of drug circulation and sales, it is inevitable to stack and place the products, which is often impacted by extrusion or external forces At this time, if the packaging of the aluminum-plastic composite film leaks or breaks due to the too large or too small sealing strength, the quality of the medicine in the packaging bag will be affected in a short time Once these deteriorated drugs enter the market, they will not only threaten the life safety of patients, but also bring a devastating blow to manufacturers Therefore, before the drug leaves the factory, the packaging must be tested for leakage and sealing strength, and the unqualified products cannot enter the market Therefore, it is urgent to detect the leakage and sealing strength of the finished product Next, we will explain the test principle of the sample and other basic contents, as well as the whole process of fracture test, hoping to give you a reference Test principle: lssd-01 leakage and sealing strength tester can automatically judge the Zui high pressure value when the sample is blasted by injecting a certain pressure gas into the sample and after a certain holding time Test scope: It is applicable to the quantitative measurement of the sealing strength, quality, bursting pressure and sealing leakage performance of all kinds of plastic anti-theft bottle caps, the overall sealing performance, pressure strength, cap body connection strength, tripping strength, sealing strength and binding strength of all kinds of hoses, and the sealing strength and sealing strength of all kinds of flexible tubes formed by various heat sealing and bonding processes Quantitative measurement of strength and other indexes Test steps: use scissors to cut a small opening on the aluminum plastic composite film packaging bag, and stick it to the 3M double-sided tape prepared in advance The other side of the double-sided tape is stuck to the silica gel pad of the instrument, and align with the punching hole of the fixture Adjust the measuring head which can be adjusted up and down freely to a proper position to ensure that the aluminum plastic composite film is placed on the flat plate of the instrument smoothly Click "experiment" to start filling the sample When the sample is blasted, the system automatically prints out the Zui high pressure value during blasting Repeat the above test five times and take the small value of pressure Zui as the test result Test results: in the five tests, the Zui small pressure value is 44.9kpa, that is, the Zui large pressure value is 44.9kpa when blasting At present, the instrument conforms to many national and national standards such as ISO 11607-1, ISO 11607-2, GB / T 10440, GB 18454, GB 19741, GB 17447, ASTM f1140, ASTM f2054, GB / T 17876, GB / T 10004, BB / T 0025, QB / T 1871, YBB 00252005, YBB 00162002 It is convenient for users to test and produce products according to different standards It really belongs to the instrument of one-time investment and lifetime profit-making Moreover, Jinan Saicheng after-sales promise: once any quality problem occurs, it can only be replaced within three months, with one-year warranty and lifetime fast service For a qualified aluminum-plastic composite film, the test of leakage and sealing strength is only one of the test indexes In addition, there should be a series of test indexes such as heat sealing strength, aluminum foil pinhole degree, tearing degree, impact resistance and sealing ability Since its establishment more than ten years ago, Jinan Saicheng has independently developed nearly 100 kinds of instruments, which can meet customers' different testing indicators for the same product at the same time, greatly improving the work efficiency As a high-tech enterprise integrating R & D, production, sales, training and service, Jinan Saicheng has always been committed to providing professional test instruments and solutions for global customers For more questions about the instruments, please call Jinan Saicheng technology directly Strength
