Abstract
A light-sensitive material package includes a light-shielding envelope containing a stack of sheet-form light-sensitive material, the light-shielding envelope having heat-seal parts on four edges. The light-sensitive material package further includes a cushioning member, which holds down all or a part of the heat-seal parts. The light-sensitive material package further includes a fitting-type box for storing the envelope, the fitting-type box being formed from an inner box and a lid. The stiffness of the heat-seal parts is at least 0.05 N·cm.
