The sealing test of plastic anti-theft caps is of great significance for product quality control of packaging manufacturers and beverage manufacturers. GB/T17876-2010 "Packaging container plastic anti-theft cap" around the use of polyolefin as the main raw material, plastic injection caps molded by injection molding, hot pressing or other processes, specifies the sealing performance requirements and test methods:
For non-carbonated caps, cover them with a capping machine at the rated torque that meets the capping requirements, test with a seal tester, pressurize to 200 kPa, hold under water for 1 min, observe for leaks, and increase the pressure to 350kPa, hold pressure for 1min, observe whether the cap is loose and pop out. It is required to not leak when it is 200 kPa, and it does not cover when it is 350 kPa.
For the carbonated cap, it is capped with a capping machine according to the rated torque that meets the capping requirements. The anti-theft ring is cut off, tested with a seal tester, pressurized to 690 kPa, and kept under water for 1 min to observe whether it leaks. Increase the pressure to 1207 kPa, hold for 1 min, and observe whether the cap is loose or popped. It does not leak when it is required to be 690kPa, and does not cover when it is 1207kPa.
The sealing test of the plastic anti-theft cap is based on the Labthink LSSD-01 leak and seal strength tester and the plastic LSSD-01C plastic anti-theft cap sealing performance test device. The specifications of the cap are applied to the thread diameter of 28mm, 38mm. The standard bottle mouth of the bottle, other specifications can also be customized. LSSD-01 Leakage and Sealing Strength Tester is specially applied to the quantitative determination of the sealing strength, heat sealing quality, and the bursting pressure and sealing leakage performance of the soft seals formed by various heat sealing and bonding processes. The quantitative determination of the sealing performance of plastic anti-theft caps, the quantitative determination of the overall sealing performance, compressive strength, cap connection strength, trip strength, tie strength and other indicators of various hoses.
Labthink is committed to helping customers cope with packaging challenges and improving the quality and safety of packaging-related industries through the development of packaging inspection technology and the development of sophisticated inspection instruments.
