Abstract
The inventors have discovered that certain hot melt adhesives can be used to form a stable stacked pallet that can limit the need for additional packaging materials e.g. inter-layer and pallet wrap.
Claims20
A stacked pallet comprising:
- a pallet,
- a plurality of layers of secondary packages stacked on the pallet, and
- a hot melt adhesive sandwiched between the layers of secondary packages thereby adhering the layers to each other, the hot melt adhesive comprising:
- a polymer selected from the group consisting of ethylene copolymers derived from ethylene and a co-monomer that includes vinyl unsaturation, styrene block copolymers, and olefin based polymers, and
- no greater than 10% by weight of a plasticizer.
2 more elements
A method of stacking a pallet comprising:
- grouping a plurality of primary packages,
- encasing the primary packages in a plastic film shrunk by heat to form a plurality of individual secondary packages,
- applying hot melt adhesive to at least two locations on the top of each of the individual secondary packages;
- and
- arranging the plurality of individual secondary packages on a pallet to form a plurality of layers, wherein the hot melt adhesive is sandwiched between two layers of secondary packages, the hot melt adhesive comprising:
- a polymer selected from the group consisting of ethylene copolymers derived from ethylene and a co-monomer that includes vinyl unsaturation, styrene block copolymers, and olefin based polymers, and
- no greater than 10% by weight of a plasticizer.
