As a core consumable for automated packaging, roll film is compatible with various automatic packaging machines in roll form, significantly improving mass production efficiency. It can be customized with material combinations (such as PE, PET, aluminum foil, etc.) according to different product needs (e.g., food, daily necessities, pharmaceutical accessories), meeting diverse protective requirements like moisture resistance, temperature resistance, and light shielding. With flexible lengths, roll film enables continuous bag making and sealing with packaging machines, reducing manual intervention and lowering packaging costs—an efficient solution for large-scale production scenarios.
