ABSTRACT:
The present invention relates to a method for shrink packaging relatively large objects such as, for example, a pallet load utilizing heat shrinkable thermoplastic structures. The thermoplastic bags are characterized by having a rectangular bottom configuration whereby when the bag structure is shrunk about the generally rectangular pallet load, the contour of the shrunken thermoplastic overwrapped material conforms substantially to the rectangular conformation of the pallet being overwrapped.
