Abstract
A unitized package contains a stack of insulation containing packages. The unitized package is formed by a sheet of stretch wrap film that is spirally wrapped about the sides and at least partially overlays the upper and lower surfaces of the stack of insulation containing packages to hold the stack of packages together as a packaged unit. The unitized package has a band adjacent the base of the unitized package which forms a loop adjacent one side of the unitized package to which a pulling means can be secured to pull the unitized package over a horizontal surface, such as a warehouse floor or truck cargo bed, to facilitate moving the unitized package or unloading the unitized package from the truck.

A unitized package containing multiple packages of insulation product, comprising:
- a stack of insulation containing packages;
- the stack of insulation containing packages having horizontally extending upper and lower surfaces and vertically extending side surfaces;
- the stack of insulation containing packages being further packaged as a unitized package within a sheet of stretch wrap film that is spirally wrapped about the side surfaces of the stack and at least partially overlays the upper and lower surfaces of the stack to hold the insulation containing packages forming the stack together as a packaged unit;
