As shown in fig. 1 to 2, a packaging structure for a refrigerator according to an embodiment of the present invention is schematically illustrated in a perspective view. As shown in fig. 1, in this embodiment, since the thin film layers are transparent, the thin film layers are individually displayed in parallel in a final state. In this embodiment, the vertical direction of the refrigerator in a state where the refrigerator is located in the packaging structure 100 is taken as the vertical direction, the surface in the direction close to the refrigerator is taken as the inner surface, and the surface in the direction away from the refrigerator is taken as the outer surface.

In one embodiment, a packaging structure 100 for a refrigerator includes a base 20 supported at the bottom of the refrigerator, a top 10 covering the top of the refrigerator, four vertical side edges and a film layer 40. Two ends of each vertical side edge are respectively connected with the base 20 and the top seat 10, and the four vertical side edges are respectively arranged at four corners of the base 20 and the top seat 10. The top base 10, the bottom base 20 and the four vertical side edges form an accommodating space for accommodating a refrigerator. In this embodiment, the film layer 40 is wrapped on the outer surface of the profile body formed by the base 20, the top base 10 and the four vertical side edges in a manner that the film shrinks when heated. The base 20, top 10, four vertical side edges and film layer 40 form a complete package structure 100.
