As a lightweight, versatile, and cost-effective material, plastic films have permeated nearly every aspect of human life. From daily packaging to cutting-edge technology, their applications continue to expand, making them an "invisible hero" driving progress across industries. Below is a comprehensi

A coating machine is a critical device that evenly applies materials such as adhesives, coatings, or inks onto the surface of substrates. Widely used in industries like printing, packaging, new energy, electronics, and automotive, its core function is to precisely control coating thickness and unifo

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
