Using lssd-01 equipment to test the bursting pressure of butterfly crisp plastic composite film packaging

Abstract: bursting pressure is a physical quantity to detect the resistance of packaging to internal gas shock or drop, and it is an important index related to whether the finished product packaging is easy to break in the circulation process Taking butterfly puff packaging as an example, this paper uses lssd-01 leakage and sealing strength tester independently developed by Jinan Languang Electromechanical Technology Co., Ltd to test its bursting pressure, introduces the test principle and the whole test process of the equipment, so as to provide a practical scheme for the enterprise to monitor the bursting pressure of packaging Key words: bursting pressure, pressure resistance, leakage and sealing strength tester, soft plastic packaging, butterfly cake, pastry, broken bag 1, significance In the transportation, sales and other circulation links of the finished product packaging, the packaging bags are easy to squeeze each other or be squeezed by other external forces or fall from the storage position When the packaging bags are squeezed or fall, the gas inside the packaging bags will have a certain impact on the packaging bag body or the hot edge If the impact resistance of the packaging bags is poor, the packaging bags are easy to be in the bag body or the hot edge The bag is broken at the hot edge However, the strength of the packaging bag against the impact of internal gas can be characterized by the explosion pressure index Butterfly cake is named for its shape like butterfly, also known as "palm leaves", "elephant ears", etc It tastes crisp, crisp, fragrant, sweet and delicious, and is a favorite pastry food In this paper, the bursting pressure of butterfly puff packaging was tested to verify its resistance to the impact of internal gas 2 At present, the commonly used packaging materials of butterfly crisp are mainly plastic composite film and aluminum-plated composite film At present, there is no forming executive standard for burst pressure test of flexible plastic packaging in China The test process mainly refers to ASTM f1140 / f1140m-2013 test method for resistance of unrestricted packaging to internal pressure damage Figure 1 common packaging form of butterfly puff packaging 3 Plastic composite film packaging bag for a brand of butterfly puff packaging 4 In this paper, Labthink blue light lssd-01 leakage and sealing strength tester is used to detect the bursting pressure of butterfly crisp packaging bag Figure 2 lssd-01 leakage and sealing strength tester 4.1 test principle equipment is designed by positive pressure method, that is, the gas pressure inside the sample is greater than that outside By filling a certain amount of gas into the inside of the package and monitoring the pressure change in the package in real time until the package breaks, the pressure value tested when the package breaks is the bursting pressure of the package, or filling gas into the inside of the sample to the specified pressure, and then placing the sample in water or other ways to check whether the sample leaks Under the impact of the gas inside the package, the weak part of the package first breaks or leaks Therefore, through the position where the package breaks or leaks, the weak part of the package can also be inferred 4.2 the scope of application is applicable to the determination of the sealing strength, heat sealing quality, bursting pressure and sealing leakage performance of various heat sealing edges, such as soft package parts and aseptic packages formed by various heat sealing and bonding processes It is suitable for quantitative test of sealing performance of various plastic anti-theft bottle caps, such as coke bottle caps, mineral water bottle caps, beverage bottle caps, etc It is applicable to the quantitative determination of the overall sealing performance, pressure strength, cap body connection strength, tripping strength, hot edge sealing strength, tie-in strength and other indicators of various hoses, such as the hose for the packaging of various washing products such as toothpaste tube, facial cleanser, and other fields such as pharmaceutical ointment tube It is applicable to the evaluation and analysis of the compressive strength, bursting strength and other indexes of the materials used in the soft packaging bag, the twist sealing index of the bottle cap, the connection tripping strength of the bottle cap, the stress strength of the materials, and the sealing, compressive strength, bursting resistance and other indexes of the whole bottle body It meets many national and international 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, BB / T 0025, ybb00252005, etc 4.3 the test range of equipment parameters and equipment is 0 ~ 600 kPa Through special customization, the test range can be increased to 0 ~ 1.6 MPa to meet the test requirements of different samples The double test methods of expansion inhibition and expansion non inhibition can be selected freely by users according to different test purposes A variety of test modes, such as rupture test, creep test, creep to rupture test, can meet the test needs of users Support Lystem TM laboratory data sharing system, and manage test results and test reports in a unified way 5 Test step (1) carefully insert the probe of the equipment into the central position of the butterfly puff packaging bag sample, and ensure that the sealing near the insertion point is good and no air leakage occurs (2) Start the test, adjust the flow valve to control the pressurization speed, so that the gas slowly fills into the sample, and the sample expands until it breaks or leaks Fig 3 test process Fig (3) record the pressure value when the sample breaks or leaks, and record the location of the break or leak 6 Test results three bags of samples were tested in this test The bursting pressure of each sample was 20.5kpa, 31.9kpa and 33.4kpa respectively, and all of them broke at the back edge of the sample 7 Conclusion lssd-01 leakage and sealing strength tester is a professional testing equipment used to test the bursting pressure of soft plastic packaging, which can truly reflect the bursting strength of the packaging bag, and find out the weak link of the whole packaging through the test, so as to provide the basis for the subsequent process improvement Labthink Languang has always been committed to providing professional testing equipment and services for customers all over the world In addition to
