Analysis of sealing test process of Labthink plastic anti-theft bottle cap

The sealing test of plastic anti-theft bottle cap is of great significance to the product quality control of packaging manufacturers and beverage manufacturers GB / t17876-2010 plastic anti theft bottle caps for packaging containers, which are made of polyolefin by injection molding, hot pressing or other processes, specifies the sealing performance requirements and test methods For the non carbonated cap, use the capping machine to seal the cap according to the rated torque meeting the capping requirements, use the sealing tester to test, pressurize to 200KPa, maintain the pressure under water for 1min, observe whether there is air leakage, then increase the pressure to 350kPa, maintain the pressure for 1min, and observe whether the cap is loose and pops out It is required that there is no air leakage at 200KPa and no cover removal at 350kPa For the carbonated cap, use the capping machine to seal the cap according to the rated torque meeting the requirements of the cap, cut off the anti-theft ring, use the sealing tester to test, pressurize to 690kpa, maintain the pressure under water for 1min, observe whether there is air leakage, then increase the pressure to 1207kpa, maintain the pressure for 1min, and observe whether the cap is loose and ejected It is required that there is no air leakage at 690kpa and no cover removal at 1207kpa Labthink lssd-01 leakage and sealing strength tester and lssd-01c plastic anti-theft bottle cap sealing performance test device are used for the sealing test of plastic anti-theft bottle cap The specification of the tested bottle cap is applicable to the standard bottle mouth with 28mm and 38mm thread diameter, and other specifications can also be customized Lssd-01 leakage and sealing strength tester is applicable to the quantitative measurement of sealing strength, sealing quality, bursting pressure and sealing leakage performance of all kinds of plastic anti-theft caps, as well as the overall sealing performance, pressure strength, cap body connection strength, tripping strength and binding of all kinds of hoses formed by various heat sealing and bonding processes Quantitative measurement of strength and other indicators Labthink Languang is committed to helping customers to deal with packaging problems and help the quality and safety of packaging related industries by improving packaging testing technology and developing testing instruments
