The invention provides a package material for shaping, and when pressing and shaping in the forming process of an angle part with extreme small bending radius, the generation of pore is inhibited. The pachage material for forming provided by the invenion has an inner and outer resin layer, and an Al-Fe aluminium alloy foil with thickness of 30-120 mu m. The Al-Fe series aluminium alloy has grains whose average grain diameter is 5-20 mu m, and many grains whose lengthes are in the range of 0.6-0.8 times of thickness of Al-Fe series aluminium alloy, which are existed in the section of the foil rolling direction of the Al-Fe series alluminium alloy foil and in the direction of the thickness direction of the Al-Fe series alluminium alloy foil. The distances between the grains are above 1 mm. |
