The protective film of the refrigerator has no effect on heat dissipation, but you should tear it off immediately because there is glue in the protective film. If it is not torn off for a long time, the glue will stick to the surface of the refrigerator. If it is torn off later, there will be offset printing on the surface of the box, and this offset printing is difficult to erase, making the refrigerator look ugly. Therefore, it is recommended that you tear off the protective film immediately after checking the appearance of the refrigerator.
