Stretchable shipping/pallet wrap and method for use
Methods and apparatus for unitizing groups of individual packages into pallet loads, stabilizing the loads and facilitating general movement of the pallets, including the loading and unloading of pallets into and out of transport vehicles, includes wrapping the loads with stretchable crepe paper, rather than conventional plastic wrap material. Crepe paper can be produced and recycled with less environmental impact than plastic wrap. These methods involve a new use for crepe paper, and a new use for conventional plastic-wrapping equipment.
1. A method for unitizing one or more packages into a shipping unit, the method comprising the steps of:
providing the one or more packages;
providing a crepe paper;
forming a supply of the crepe paper;
dispensing the crepe paper from the supply of the crepe paper, while longitudinally tensioning the crepe paper, thereby creating a stretched crepe paper;
wrapping the one or more packages with the stretched crepe paper a total of at least about one turn, thereby wrapping the shipping unit with overlapping layers of the stretched crepe paper; and
applying an adhesive to at least one side of the crepe paper prior to forming the supply of the crepe paper.
2. The method of claim 1 , wherein the adhesive is applied to both sides of the crepe paper.
3. The method of claim 1 , wherein the adhesive is applied by brushing, painting, or spraying the adhesive.
4. The method of claim 1 , further comprising the step of activating the adhesive by applying an activator to the stretched crepe paper.
5. The method of claim 4 , wherein the activator is applied by spraying the activator on to the stretched crepe paper.
6. The method of claim 1 , further comprising the step of activating the adhesive by heating the stretched crepe paper.
7. The method of claim 6 , wherein a heat gun or infrared light source is used to heat the stretched crepe paper.
8. The method of claim 1 , wherein the adhesive is applied by painting or spraying the adhesive to the at least one side of the crepe paper, and further comprising the step of drying the adhesive prior to forming the supply of crepe paper.
