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 a plurality of individual packages into a single shipping unit, the method comprising:
disposing the individual packages adjacent each other horizontally and/or vertically to form a close-packed group of packages;
providing a supply of crepe paper comprising a fire retardant, the crepe paper having a basis weight of about 15-50 GSM, prior to creping, and being capable of stretching at least about 10% without tearing;
dispensing crepe paper from the supply of crepe paper, while longitudinally tensioning the crepe paper, so as to longitudinally stretch the crepe paper at least about 10%, thereby creating stretched crepe paper; and
while maintaining longitudinal tension on the stretched crepe paper, circumferentially wrapping the close-packed group of packages with the stretched crepe paper a total of at least about one turn, each turn overlapping at least about 10% of at least a portion of another turn, thereby creating a single shipping unit.
2. A method according to claim 1 , wherein:
disposing the individual packages comprises disposing at least some of the individual packages directly on a pallet; the method further comprising:
circumferentially wrapping at least a portion of the pallet with the stretched crepe paper a total of at least about one turn around the pallet while maintaining the longitudinal tension on the stretched crepe paper.
3. A method according to claim 1 , wherein:
the crepe paper includes an adhesive disposed on at least a portion thereof; the method further comprising:
adhering the stretched crepe paper to itself by the adhesive, at least in regions of overlap of the stretched crepe paper.
4. A method according to claim 3 , wherein the adhesive comprises a wax.
5. A method according to claim 1 , further comprising, after circumferentially wrapping the close-packed group of packages, applying an adhesive to at least a portion of the stretched crepe paper.
6. A method according to claim 1 , wherein the crepe paper includes water repellant.
7. A method according to claim 1 , wherein the crepe paper includes sizing.
8. A method according to claim 1 , wherein the supply of crepe paper comprises a roll of crepe paper, the crepe paper being at least about 10 inches (25.4 cm) wide and at least about 300 feet (91 m) long.
