Abstract

Abstract A method for packaging frame, coil or ring shaped articles stacked on a pallet with a shrink film wrapping. The articles are stacked on the pallet over a guide element which projects upwardly through a recess in the pallet. In some embodiments the articles are compressed after being covered with a shrink film wrapping. The wrapping is heat-shrunk about the stack of articles and portions of the pallet. In some embodiments the guide element is telescoping and is removed through the pallet recess after the wrapping is heat-shrunk.
