Embodiment 1
[0147] Polybutylene terephthalate (Novaduran 5010R5, manufactured by Mitsubishi Engineering Plastics, Inc., melting point: 224°C) as a crystalline aromatic polyester resin for the surface layer, and a linear polyolefin-based resin as the intermediate layer Low-density polyethylene (Excellen FX (CX5501), produced by Sumitomo Chemical Co., Ltd., melting point 66°C), ethylene-methyl methacrylate copolymer (Acryft (WH401), manufactured by Sumitomo Chemical Co., Ltd., melting point 86°C) and polypropylene (PS207A , manufactured by Sunallomer, melting point 160° C.), was put into a co-extrusion molding machine, and co-extruded with a T-die to obtain a film with a thickness of 10 μm in the surface layer and a thickness of 80 μm in the middle layer. In addition, the melting point was measured using a differential scanning calorimeter (DSC 2920, manufactured by TA Instruments).

Embodiment 2～5
[0152] As shown in Table 1, except having changed the material and working energy (KJ) of the surface of a rubbing process material, it carried out similarly to Example 1, and obtained the release film.
[0153] The obtained release film was observed with a transmission electron microscope (TEM) (Model H-9500, manufactured by Hitachi High-Tech Co., Ltd.) to observe the cross section cut in the thickness direction using a slide microtome (Model SM2000R, manufactured by Ikeda Rika Co., Ltd.) , the mold release treatment layer was observed only in the region from the surface of the surface layer to the thickness (nm) shown in Table 1. The image observed by a transmission electron microscope in Example 2 is shown in Figure 5 , the image observed by a transmission electron microscope in Example 3 is shown in Figure 6 , the image observed by a transmission electron microscope in Example 5 is shown in Figure 7 . In addition, the crystallinity (%) of the surface layer was calcul...
