How to Improve the Sealing Performance of Product Packaging

  The sealing performance of packaged products has long been a core issue of key concern for various enterprises. Currently, roll film products in the industry exhibit complex and variable characteristics, and their materials are also becoming increasingly diversified. Classified by material, common types include nylon, aluminum-plated film, cotton paper, etc.

  To ensure good sealing performance of products, it is necessary to accurately adjust the sealing temperature and pressure of the packaging machine based on the stability and pressure-bearing characteristics of the packaging film material. If the pressure of the packaging machine is too high, it is easy to cause damage to the sealing part. This problem most frequently occurs at the joint of the end seal and the middle seal - this part has a greater thickness and is a high-fault area. In addition, if the oxygen barrier layer of the packaging film is damaged due to excessive pressure, it will directly lead to product air leakage. It is worth noting that the part precision and mechanical characteristics of the packaging machine are also crucial, as they not only directly affect the stability and sealing performance of product packaging but also play a key role in the wide applicability of the packaging films that the equipment can use.
