Stretch Film suppliers Advantages of Nano Film Roll 1. The number of layers produced by common co-extruded film technology is higher, generally 2-17 layers; 2. The more the number of layers, the better the physical and mechanical properties of the film material, which is mainly reflected in the geometrical increase in elongation, and can withstand higher load force and puncture strength; 3. Due to the problem of the production process, it is difficult to achieve a complete uniform thickness of ordinary films, and even discontinuities occur during the extrusion process. And the manufacturing cost is high. In addition, there will be a
