In food packaging, it serves as the material of choice for instant noodles, frozen foods, and snack packaging bags. For example, a renowned instant noodle brand uses BOPP heat-sealable film for bowl noodle lids, achieving precise sealing within 3 seconds via high-speed heat-sealing equipment. This n

Polymer materials represent a discipline that is both ancient and modern. Its ancient roots lie in human utilization, dating back to antiquity when natural polymers such as resins, rubber, animal hides, silk, cotton, cellulose, and wood were already in use. Yet, as a scientific and engineering field

Electrostatic charges in film production arise primarily from the following causes:Electrostatic Generation During Film ProductionStatic electricity is generated during film production due to friction between polymer particles, friction between the melt and the die, and friction between the formed f

As friction in film production is unavoidable, static electricity affects production in the following main aspects: Printing DifficultiesDue to (minor static discharge), burrs or fluffy (whisker-like) ink overflow often appear at the edges of printed patterns. Static electricity charges the ink,

The rapid development of biaxial stretching technology has brought revolutionary changes to the flexible packaging market. There are three main development directions for global biaxial stretching technology. First, ordinary packaging products will place greater emphasis on low cost and high efficie
