A method of and apparatus (100) for building and stretch wrapping loads of layers of load units (36) that includes the steps of providing at least one layer of load units (36) in a load building (17) and wrapping area (13), applying horizontal compression (140,142,144) to the at least one layer, subsequently applying vertical compression (154) to the at least one layer while applying the horizontal compression, releasing the horizontal compression (140,142,144) while retaining the vertical compression, rotating (106) the at least one layer relative to a packaging material dispenser (109) to apply packaging material (111) around the at least one layer while retaining the vertical compression, and releasing the vertical compression.
