Systems and methods for packing a shipping container. The methods comprise: detecting, by a computing device, a presence of the shipping container; generating, by a computing device, a 3D point cloud comprising a 3D perspective representation of interior of the shipping container and surfaces of at least one item disposed in the shipping container; analyzing, by a computing device, the 3D point cloud to identify a void area inside the shipping container, the void area being absent of the at least one item; selecting, by the computing device, a percentage from a plurality of possible percentages based on a characteristic of the void area; and causing, by the computing device, protective packaging to be dispensed into the void area such that the selected percentage of the void area is filled with the protective packaging.
