Patent ID: 7638204

Claim:
In combination, a tier sheet, adapted for interdisposition between stacked layers of a plurality of cans disposed upon a pallet so as to form, with said stacked layers of said plurality of cans, a palletized load, consisting of: a plurality of cans arranged in stacked layers upon a pallet; and a tier sheet adapted for interdisposition between said stacked layers of said plurality of cans disposed upon said pallet so as to form, with said stacked layers of said plurality of cans, said palletized load, said tier sheet consisting of only a three-layer laminate structure consisting of only a pair of oppositely disposed outermost layers, consisting of a polypropylene homopolymer, and an inner core layer, interposed between said pair of oppositely disposed outermost layers, consisting of a blend of a polypropylene copolymer and an elastomer, wherein said tier sheet, consisting of only said three-layer laminate structure consisting of only said pair of oppositely disposed outermost layers consisting of a polypropylene homopolymer, and said inner core layer, interposed between said pair of oppositely disposed outermost layers and consisting of a blend of a polypropylene copolymer and an elastomer, exhibits a sufficient amount of softness, elasticity, and resiliency so as to permit said cans to form sufficiently deep impressions and depressions within said oppositely disposed outermost layers of said tier sheet so as to effectively restrain movements of said cans while said cans are disposed upon said tier sheet within said palletized load, and yet permit said tier sheet to dimensionally recover, after said cans are removed therefrom, whereby said impressions and depressions will effectively disappear such that said tier sheet will be ready for subsequent use in connection with the stacking of new cans within a new palletized load.
