Discussion on the sealing performance of plastic bottle caps

Discussion on the sealing performance of plastic bottle caps At present, the application of plastic packaging in food, beverage, beer and other fields is increasing, and it has successfully replaced traditional packaging forms in many fields. In plastic packaging, packaging manufacturers pay more attention to the sealing performance of plastic packaging, because its sealing performance is related to the preservation quality and time of the contents. However, the sealing performance of plastic bottle caps and bottle mouths is an important factor affecting plastic packaging containers, so in recent years, the detection of the sealing performance of plastic bottle caps and bottle mouths has attracted much attention from the industry. National Standards for Sealing Performance Testing of Bottle Caps

In the above-mentioned national standards, we can see that the test of the sealing performance of the bottle cap is carried out under a certain torque force of the bottle cap. Let's briefly talk about the relationship between the torque force of the bottle cap and the sealing performance of the bottle cap. The torque force of the bottle cap is the main factor affecting its sealing performance. Excessive torque force will bring great difficulties to the opening and locking of the bottle cap.

The convenience of use is reduced, and the small torque force will reduce the sealing performance of the container, which may lead to leakage of the product during transportation. Today's packaging design needs to provide more convenience for fast consumption, and easy opening of bottle caps is one of the goals to be achieved.

However, while reasonably controlling the ease of opening of the bottle cap, attention must be paid to testing the sealing performance that is closely related to it, otherwise it will bury hidden dangers for leakage due to insufficient torque. It can be seen that the sealing performance of the bottle cap is also a key detection index to realize the convenient consumption of the container.

The sealing performance of the bottle cap is not only an important indicator for evaluating whether the bottle cap is qualified, but also can not only scientifically evaluate the sealing performance of the container, but also reasonably control the opening of the bottle cap under the premise of ensuring the safety of the packaging. Try to avoid the inconvenience caused by excessive control of sealing performance. The "creative style" of the beverage plastic bottle cap market is in this extraordinary period.
