How good is the sealing effect of the bottle seal? Can you ensure that eyeliner or eyebrow pencil won't leak?

In the empty eyeliner tube/eyebrow pencil tube we designed, the bottle sealing ring is a crucial component, which is directly related to the use experience and safety of the product.
First of all, the material selection of the bottle sealing ring is very particular. We selected a polymer material with excellent elasticity and wear resistance. This polymer material not only has excellent elasticity, but also can closely fit the gap between the bottle mouth and the pen body when tightening the pen barrel, forming a strong seal. Barrier to prevent liquid eyeliner or eyebrow pencil from leaking. At the same time, it also has excellent wear resistance and can withstand the test of long-term use and frequent opening and closing, ensuring the durability of the sealing ring. This polymer material also has stable performance under various temperature and humidity conditions. Whether it is cold winter or hot summer, whether it is a dry indoor or a humid bathroom, it can maintain its original elasticity and sealing. performance to ensure product stability and reliability.
Secondly, the design of the bottle seal has been carefully considered. It adopts a unique structure that can fit tightly into the gap between the bottle mouth and the pen body, forming a solid barrier. When the user tightens the pen barrel, the sealing ring will be evenly squeezed, ensuring a tighter fit with the bottle mouth and pen body, effectively preventing liquid or paste from leaking from any gaps.
In order to ensure that the sealing ring has the best sealing effect, we also conduct rigorous testing on it. These tests include pressure tests, durability tests, and waterproof tests, among others. During the pressure test, we simulated usage scenarios under different pressures to verify whether the sealing ring could withstand various pressures without leaking. In the durability test, we simulated long-term use and frequent opening and closing to evaluate the wear resistance and service life of the seal. In the waterproof test, we simulated usage scenarios in a humid environment to verify whether the sealing ring can effectively waterproof.
After these rigorous tests, our bottle seals demonstrate excellent sealing performance. Whether in daily use or in special circumstances, it can effectively prevent the leakage of liquid eyeliner or eyebrow pencil. This not only ensures the effectiveness of the product, but also avoids waste and pollution caused by leakage.
In addition, we also designed the bottle sealing ring in a user-friendly manner. It is easy to install and remove, making it convenient for users to clean and replace. At the same time, we also provide users with a variety of color choices to meet the personalized needs of different users.
To sum up, the bottle sealing ring of our empty eyeliner tube/eyebrow pencil tube has excellent sealing effect, which can ensure that the liquid eyeliner or eyebrow pencil will not leak during use and storage. We are committed to providing you with high-quality, safe and reliable products, making your use more secure and secure.
