The utility model discloses a multi-surface flexible package decorating structure comprising a flexible package surface layer and a base material layer. The base material layer is made of a PVC sectional material. The section of the base material layer is arc. The flexible package surface layer covers the arc surface of the base material layer. The PVC sectional material is formed by conducting modeling through computer software and inputting radian data of the curved surface to a PVC sectional material mould precisely cut and manufactured by a numerically-controlled machine tool. According to the multi-surface flexible package decorating structure, the base material layer is formed by the PVC sectional material, then the flexible package surface layer covers the base material layer, and wrinkles are avoided; besides, the PVC sectional material is formed by conducting modeling through the computer software and inputting the radian parameters of the curved surface to the PVC sectional material mould precisely cut and manufactured by the numerically-controlled machine tool according to actual needs, the radian of the curved surface can be controlled uniformly, and therefore installation is easy, the construction cost is low, and construction efficiency is improved.
