Advanced Production Technology of Oil Film, Powder Film and Automatic Packaging Roll Film

　　The production of oil film, powder film and automatic packaging roll film requires mature technology and precise control. The whole process includes material preparation, extrusion casting, printing, compounding, curing and slitting.
　　First, manufacturers select high-quality raw materials such as PET, PE, BOPA and VMPET. Different materials are matched according to the purpose of the film. For oil film, oil-resistant materials are used; for powder film, high-barrier materials are selected.
　　Next, extrusion and casting processes form the basic film structure. The thickness is strictly controlled to ensure uniformity. Then comes high-definition gravure printing, which can print brand patterns, text and instructions with bright colors.
　　The compound process combines multiple layers to improve strength, barrier and sealing performance. After compounding, the film enters the curing chamber to stabilize adhesion. Finally, slitting machines cut the film into required widths.
　　During production, online inspection systems check for defects such as spots, bubbles and misalignment. Strict quality control ensures stable performance of oil film, powder film and automatic packaging roll film.
　　Advanced technology makes these films have high reliability and long service life. With continuous technological innovation, packaging films are becoming more eco-friendly, high-performance and intelligent.
