How is the leak-proof design of plastic threaded caps achieved?

Plastic Screw Cap plays an important sealing role in packaging containers, and its leak-proof design is one of the keys to ensuring product quality and safety. Sealing gasket is a common method in the leak-proof design of Plastic Screw Cap. These seals are usually made from rubber rings or silicone gaskets that fill the tiny gaps between the threads, ensuring a tight seal. By providing a soft and elastic gasket, the seal can adapt to irregular surfaces between threads, effectively preventing the penetration of liquids or gases.

Thread design is crucial to the leak-proof performance of Plastic Screw Cap. Reasonably designed and high-precision threads can ensure that the threads of the lid and container fit well and form a good sealing effect. Precision thread design can minimize gaps and improve sealing performance, thereby effectively preventing leakage.

By designing the sealing lip, enlarging the sealing area, and adopting multi-layer sealing, the leakage prevention performance can be further improved. These designs and measures jointly ensure the tight connection between the Plastic Screw Cap and the container, effectively prevent the leakage of liquid or gas, and ensure the quality and safety of the product.
