1. A method of unwrapping a generally parallelepiped palletized load comprising:
providing a palletized load surrounded by a plastics material,
making vertical and/or horizontal linear cuts in the plastics material which surrounds the palletized load, wherein at least one of the linear cuts has a discontinuous cut portion which comprises a plurality of cuts of a certain length and constant pitch, and
tearing said discontinuous cut portion,
trapping the torn edges of the plastics material that surrounds the palletized load by robotic arms to hold said plastics material and
subsequently advancing the palletized load to unwrap the palletized load.
