[0002] Airtightness refers to whether the closed space formed by the material itself or between the material and the packaging can effectively prevent the entry of outside air and water vapor or the overflow of internal substances. In modern industry, packaging has become an important link in ensuring product quality and safety. Especially for the food industry, safe and hygienic food packaging is of vital importance. Airtightness is a key performance indicator in food packaging, which is not only related to the freshness and quality stability of the product, but also to the safety and experience of consumers. If the airtightness of food packaging is not good, microorganisms or impurities may enter the food, which may easily cause the food to deteriorate and corrupt, thus bringing food safety risks to consumers.
