    Abstract: compared with other packaging, liner box packaging has the advantages of good economy, environmental protection, easy disposal and so on, so its application in the field of food is expanding rapidly; at the same time, its quality control requirements are more and more standardized; in addition to the quality safety of the content itself, the quality safety and detection of liner box packaging are also more and more concerned by the production enterprises Key words: quality control and inspection of liquid food packaging liner box, pressure difference gas permeameter, sealing performance, torsion, sealing tester, torque tester, leakage and sealing strength tester text: liner box refers to the inner layer of the outer packaging box with a layer of plastic or paper bag packaging content Compared with other packaging, liner box packaging has the advantages of good economy, environmental protection, waste and easy treatment, so its application in the field of food is expanding rapidly; at the same time, its quality control requirements are increasingly standardized; in addition to the quality and safety of the content itself, the quality, safety and testing of liner box packaging has also attracted more and more attention of the production enterprises Next, Labthink blue light introduces the quality control and inspection of the liquid food packaging liner box with the combination of pressure difference gas permeation instrument, sealing tester and torque instrument Jinan Languang Electromechanical Technology Co., Ltd is willing to enhance exchanges and cooperation with enterprises and institutions in the industry 1、 The sealing performance test of the liquid food packaging liner box refers to the reliability of the packing seal of the liner box Through this test, the integrity of the whole product packaging seal can be ensured, and the leakage, pollution, deterioration and other problems caused by the poor sealing performance of the product can be prevented There are many ways to test the sealing performance The commonly used method of Zui is to use the sealing tester, such as mfy-01 sealing tester of Labthink blue light Based on the principle of vacuum, keep it at - 30KPa, - 50kPa, - 70kpa, - 90kpa for 0.5min according to the national standard For vacuum packaging, it is mainly to observe the recovery of the sample after the test Of course, the above method is based on the principle of visual inspection, which is a qualitative test method If you want to quantitatively test the sealing and leakage performance of the packaging of the bag lined box, you can use the positive pressure principle sealing performance test equipment, such as lssd-01 leakage and sealing strength tester of Labthink blue light 2、 Detection of gas resistance performance of liquid food packaging liner box gas resistance performance refers to the barrier effect of liner box packaging materials on oxygen Gas resistance performance is an important factor affecting the quality of products in the shelf life, and also an important reference for the analysis of shelf life If the air blocking performance of the packing material is poor, it will lead to the oxidation and deterioration of the content due to its sensitivity to oxygen The gas resistance performance is measured by the gas transmission of materials, and relevant standards clearly stipulate that the gas transmission test shall be conducted in accordance with GB / T 1038-2000 test methods for gas transmission of plastic films and sheets - pressure difference method Labthink blue light's VAC series differential pressure gas permeameter has excellent options, all indexes are superior to the requirements of national standards or international standards, and the performance is stable and reliable In addition to the detection function of gas transmission, it also has the test function of diffusion coefficient, permeability coefficient and solubility coefficient, which can meet the needs of scientific research institutions and colleges to analyze and improve the barrier performance of materials Demand 3、 The measurement of the cap torque of the liner box of liquid food packaging is one of the key process parameters controlled offline or online by the production unit Whether the torque value is suitable or not has a great influence on the intermediate transportation and Zui final consumption Njy-20 torque meter of Labthink blue light is controlled by microcomputer, which is easy to operate and friendly to human-computer interaction It has double measurement modes of locking force and opening force, and the peak value is kept automatically The results are displayed in various units and can be statistically analyzed With high measurement accuracy and good stability, it is an indispensable test equipment in the production process Of course, after the air blocking performance, sealing performance and cap torque index of the bag lined box package are qualified, other indexes such as sealing strength and tensile performance need to be controlled to ensure the shelf life and use adaptability of the product For more information about testing technology and instruments, please check the specific information or call Jinan Languang for details
