Shrink wrap system for products on pallets and slip sheets

A package comprising a supporting pallet or slip sheet, at least one container resting thereupon, an open mesh net at least partially enclosing the container, the net being formed from a heat shrinkable fiber material and being heat shrunk into engagement with the container, the net being woven and having warp and weft fibers of approximately the same degree of stretch whereby substantially the same degree of shrinkage exists in both the warp and weft fibers.

A package comprising a pallet or slip sheet, at least one container resting thereupon, an open mesh net at least partially enclosing the container and pallet or slip sheet, the net being formed from a heat shrinkable synthetic, resinous material and being heat shrunk to engage the container, the net comprising threads formed from a thermoplastic material with a predetermined degree of pre-stretch prior to heat shrinking.

A package comprising a base comprising a pallet or slip sheet, one or more articles thereon, a tube of heat shrinkable woven net material including a generally rectangular sheet of heat shrunken net material engaging the articles and having its cut ends bonded together to form the tube, said tube having a longitudinally extending seam, the tube having two sets of mutually perpendicular fibers, the first set running parallel to the axis of the tube and the second set running at right angles thereto, said tube terminating at upper and lower circular edges and being formed from stretched strands of a thermoplastic resinous material with the number of fibers per lineal inch being on the order of about 1.5 to 5.5.

The package of claim 13 wherein the polyolefin comprises polypropylene.

A method of wrapping loads placed on pallets or slip sheets to stabilize the load and prevent moisture condensation comprising providing a heat shrinkable woven net material having thermoplastic resinous fibers running in at least two mutually perpendicular directions, placing the net around the load, exposing the thus wrapped load to a source of heat to shrink the net material onto the load to stabilize the load and the draw the net material against the outer surface of the load.
