Claims
- 1. A pallet load comprising a plurality of articles in a predetermined stacked array wrapped with at least two substantially superimposed wraps of a plastic film web stretched above 100 percent and beyond its yield point, said web being wrapped ont he pallet load with a first containment force, said containment force substantially increasing through the passage of time after the pallet has been wrapped until the containment force on the load is at least ten percent greater than the original containment force.
- 2. The article loaded pallet of claim 1 wherein the plastic film web wrapped around the palletized load is a linear low density polyethylene.
- 3. The article loaded pallet of claim 1 wherein the plastic film web wrapped around the palletized load is a polyvinylchloride.
- 4. The article loaded pallet of claim 1 wherein the plastic film web wrapped around the palletized load is a ethylvinylacetate.
- 5. The article loaded pallet of claim 1 wherein the plastic film web wrapped around the palletized load is a low density polyethylene.
- 6. The palletized load as claimed in claim 1 wherein said containment force increases over fifty percent from the original containment force placed upon the load.
- 7. The palletized load as claimed in claim 1 wherein said containment force increases over one hundred percent from the original containment force placed upon the load.
- 8. A load as claimed in claim 1 wherein the stretched film web is wrapped around the load at more than 100 linear feet per minute.
- 9. A unit load comprising a plurality of articles in a predetermined array and having at least two substantially superimposed wraps of a plastic film web stretched beyond its yield point at a predetermined amount of stretch above 100 percent and wrapped on the pallet load with a first containment force which is less than the force required to stretch the film, said containment force increasing through the passage of time after the pallet has been wrapped so that the containment force on theload is greater than the original containment force of the load when initially wrapped with the mil thickness of the film web being reduced from its original mil thickness while retaining substantially its same strength.
