Plastic anti-theft bottle caps are widely used in packaging fields such as beverages, pharmaceuticals, and daily chemicals. Plastic anti-theft caps shoulder the performance of sealing packaging and also need to have a disposable function to ensure that the connection bridge of the anti-theft ring cannot be restored to the original packaging form after opening, and consumers can intuitively judge whether the packaging is opened for the first time. The sealing performance of anti-theft bottle caps is directly related to the safety of the product and the anti-counterfeiting effectiveness of the manufacturer's brand. Therefore, conducting a sealing test on plastic anti-theft bottle caps is of great significance. This test can verify whether the bottle cap can effectively prevent leakage and detachment when in a closed state, ensuring the safety and stability of the product during transportation, storage, and use.

Sealing test of plastic anti-theft bottle cap
According to the BB/T 0025-2004 plastic anti-theft bottle cap standard, the sealing test is a key step in measuring whether the anti-theft bottle cap is qualified and usable. The plastic anti-theft bottle cap sealing tester ZYY-08A from Ruilai Platinum can be used for positive pressure testing and observation of the sealing condition of the bottle cap to ensure that in actual use scenarios, the bottle cap can maintain a good sealing effect and prevent external air, microorganisms, and pollutants from entering the bottle.

1、 Prepare the sample
1. Remove the anti-theft ring (strip) from the bottle cap.
2. Use a fixed point torque of not less than 1.0N · m to tighten the bottle cap; If the bottle cap manufacturer provides requirements for tightening values, then seal the bottle according to their requirements.
2、 Sealing test
1. Connect the anti-theft bottle cap with the provided fixture, then insert it into the water according to the standard requirements, and set it on the operation interface of the intelligent sealing instrument ZYY-08A.
2. One click start test, slowly increase the pressure to 200kPa and maintain it for 1 minute.
3. Check for air leaks or looseness
During the testing process, immerse the sample underwater and carefully observe for any bubbles to determine if the bottle cap is leaking or loose. If there is no leakage or loosening during the testing period, it indicates that the bottle cap has good sealing performance.
3、 Result judgment
During the pressurization and holding stages, if the bottle cap does not leak or loosen, it indicates that its sealing performance meets the requirements.
If the bottle cap leaks or becomes loose during testing, it is necessary to replace the unqualified bottle cap and further optimize and improve it.
