We like to drink carbonated drinks in summer, but most people don’t know why carbonated drinks are called carbonated drinks. In fact, this is because carbonic acid is added to the carbonated beverage, which makes the beverage have a unique taste. Because of this, carbonated drinks contain a lot of carbon dioxide, which makes the pressure in the bottle very high. Therefore, carbonated drinks have higher requirements for bottle caps. The characteristics of short plastic bottle caps make them meet the needs of carbonated drinks.
However, such application is difficult, of course, mainly reflected in carbonated drinks. For the current beverage industry, in order to better reduce costs, suppliers have focused on the PET bottle mouth. Making the bottle mouth shorter has become their favorable measure. PET bottles with short bottle mouth were first used in the beer industry and achieved success.
At the same time, this is why short plastic bottle caps were first used in PET bottles of beer. All its sterile products are packaged with such a short bottle mouth. Undoubtedly, PET packaging in the beverage industry has ushered in its important revolution.
Theoretically, the bottle mouth and plastic bottle cap are sealed by mutual thread contact. Of course, the larger the area between the thread and the bottle mouth, the better the degree of sealing. However, if the bottle mouth is shortened, the plastic bottle cap will also be shortened. Accordingly, the contact area between the thread and the bottle mouth will also be reduced, which is not conducive to sealing. Therefore, after complex tests, some enterprises have designed the best thread design of bottle mouth and plastic bottle cap, which can meet the sealing requirements of beverage products.
