It is a processing technology that slits (cuts) roll-shaped film material into widths of a few millimeters and then winds it up. We can accept manufacturing contracts, so please feel free to consult with us!
■High Slitting Technology We can handle not only polyethylene terephthalate (PET) but also soft materials like polypropylene (PP) and metal processing such as aluminum foil. We suppress film elongation, distortion, and burrs at the film edges. Even for soft materials that are prone to stretching and deformation, we can achieve long-length winding without seams. ■Wide Range of Applications ● Cutting widths can be accommodated from a minimum of 2mm. ● Film thickness can be accommodated from 12μm to 200μm. * The available cutting widths and film thicknesses vary depending on the material of the film. ■Individual Management By attaching labels with barcodes printed on rolls, individual management becomes possible. ■Vacuum Packaging Vacuum packing significantly reduces misalignment and contamination during transportation. 【We offer contract manufacturing for micro-slit processing】 If you have any manufacturing concerns, please feel free to contact us.
