[0026] Furthermore, the first inner core 102 is pasted inside the first outer skin 101 in the box body 1, and the four sides of the first inner core 102 are hollow to form a first filling groove 103. The first outer skin 101 is the first inner core 102 pasted inside to support the corrugated box, and the first filling groove 103 is used to fill the objects that need to be supported to make the corrugated box more pressure-resistant.

[0027] Furthermore, a first inner skin 104 is pasted on the inner side of the first inner core 102, and V-shaped protrusions 105 protrude from the four corners of the inner side of the first inner core 102. The inner side of the first inner skin 104 is hollow to form a groove 106. The first inner skin 104 is used to paste to the inner side of the corrugated box, and the V-shaped protrusions 105 are used to further enhance the pressure resistance of the inside of the corrugated box.

[0028] Furthermore, a corrugated filler 107 is pasted inside the groove 106, an insert plate 108 is pasted inside the corrugated filler 107, and a second inner core 109 is pasted inside the insert plate 108. Pasting the corrugated filler 107 inside the groove 106 is used to further enhance the compressive resistance so that the corrugated box can further support heavy objects when they are pressed on top, and pasting the second inner core 109 inside the insert plate 108 is used to further enhance the compressive resistance inside the corrugated box.
