What factors affect the sealing performance of PP cosmetic jar

As a common cosmetic packaging container, PP cosmetic jars play a vital role in protecting the freshness and quality of cosmetic products. Its sealing performance is affected by many factors, from material selection to production process.
First of all, material selection is a key factor affecting the sealing performance of PP cosmetic jars. PP material itself has good sealing performance, but in actual production, special additives or coatings are usually added to improve its sealing performance and effectively prevent the penetration of oxygen and moisture.
Secondly, the design structure is also one of the important factors affecting the sealing performance of PP cosmetic jars. PP cosmetic jars with good sealing performance usually have excellent sealing structure design, such as threaded caps, sealing gaskets, etc., which can effectively prevent the intrusion of external factors and maintain the freshness and stability of the product.
The exquisiteness of the production process also directly affects the sealing performance of PP cosmetic jars. Factors such as the accuracy of the sealing process, the material and thickness of the sealing gasket, and the matching degree of the bottle mouth and the lid will affect the quality of the sealing performance. Therefore, it is necessary to strictly control each link in the production process to ensure that the sealing performance of the product meets the standard requirements.
In addition, external environmental factors such as temperature and humidity will also affect the sealing performance of PP cosmetic jars. During storage and use, care should be taken to avoid the effects of high temperature, humidity and other environments on the sealing performance of the product to maintain the stability of its sealing performance.
Finally, the correct use method is also crucial to the sealing performance of PP cosmetic jars. Users need to properly cover the bottle cap during use to avoid damaging the sealing structure to ensure that the sealing performance of the product is not affected.
