The sealing performance of a bottle cap generally refers to the sealing performance of the bottle mouth and lid. A bottle cap with good sealing performance can prevent the leakage of gas and liquid inside the bottle. For plastic bottle caps, the sealing performance is an important criterion for evaluating their quality. Some people think that the sealing performance of the bottle cap is determined by the thread. In fact, this concept is wrong. In fact, the thread does not help the sealing performance of the bottle cap.
Generally speaking, there are three areas of bottle caps that provide sealing capabilities, namely the inner sealing of the bottle cap, the outer sealing of the bottle cap, and the top sealing of the bottle cap. Each sealing area produces a certain amount of deformation with the bottle mouth. This deformation constantly exerts a certain force on the bottle mouth, thereby producing a sealing effect. Not all bottle caps will use three seals. Most bottle caps use Just seal inside and outside.
For bottle cap manufacturers, the sealing performance of bottle caps is an item that requires continuous monitoring, that is, the sealing performance needs to be tested regularly. Perhaps many small-scale bottle cap manufacturers do not pay much attention to the testing of bottle cap seals. Some people The original and simple method may be used to test the sealing, such as sealing the bottle cap and using hand squeezing or foot stepping to test the sealing.
In this way, sealing testing can be carried out regularly when producing bottle caps, reducing the risk of production quality accidents. I believe this information can be of great help to various bottle cap factories. According to the requirements, the sealing requirements are divided into the following two categories, so our sealing standards are implemented according to the following requirements. Of course, the bottle cap factory can also improve the test standards based on the performance of the bottle caps.
