The cushioning material is assembled by: bending a single sheet, which comprises a bottom sheet, a first side sheet, a second side sheet, and an upper sheet, into a rectangular cylinder shape and inserting second flaps and an interlocking sheet in an insertion hole of a middle sheet; bending each first flap away from the first side sheet and bending the middle sheet towards the first side sheet to fit together second interlocking grooves with first interlocking grooves; bending the interlocking sheet to be roughly perpendicular to the upper sheet and bending the second flaps to be roughly perpendicular to the interlocking sheet to engage interlocking sections with the first flaps. |
