Abstract
Abstract An improved wrapping material for palletized loads which are tension wrapped is disclosed. A plastic net material comprising the plurality of sets of strands, the strands of at least one said set being substantially parallel, is oriented along said one said set to have a stretch factor of less than 15% in the oriented direction. This net is used for wrapping about pelletized loads and gives substantially improved results over known plastic net materials used in tension wrapping of palletized loads.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
104 words
In a palletized load utilizing a plastic net material as the pallet wrap, the improvement comprising said plastic net when it is wrapped about said palletized load being composed of a plurality of sets of spaced strands, the strands of at least one set being substantially parallel and being in the longitudinal direction of the net, said one set of strands being stretch-oriented to a sufficient degree so that it is incapable of being stretched further by more than about 15% in said stretch-oriented direction when stressed under the tension to which normal palletized loads are subjected at temperatures up to about 180° F.
Claim 2
Dependent Claim
104 words
In a palletized load utilizing a plastic net material as the pallet wrap, the improvement comprising said plastic net when it is wrapped about said palletized load being composed of a plurality of sets of spaced strands, the strands of at least one set being substantially parallel and being in the longitudinal direction of the net, said one set of strands being stretch-oriented to a sufficient degree so that it is incapable of being stretched further by more than about 15% in said stretch-oriented direction when stressed under the tension to which normal palletized loads are subjected at temperatures up to about 180° F.
Claim 3
Dependent Claim
23 words
The pallatized load of claim 1 wherein said one set of strands is incapable of being stretched further by more than about 10%.
Claim 4
Dependent Claim
53 words
The palletized load of claim 1 wherein said plastic netting material is polypropylene, has about 10 to 20 strands per 10 inches of longitudinal strands and about 2 to 6 strands per 10 inches in a direction transverse to the longitudinal direction and weighs about 3 to 7 pounds per thousand square feet.
Claim 5
Dependent Claim
22 words
The palletized load of claim 1 wherein the plastic net material is selected from the group consisting of polyolefins, polyamides and polyesters.
Claim 6
Dependent Claim
13 words
The palletized load of claim 1 wherein said plastic net material is polypropylene.
Claim 7
Dependent Claim
15 words
The palletized load of claim 1 wherein said plastic net material is high density polyethylene.
Claim 8
Dependent Claim
27 words
The palletized load of claim 1 wherein each set of strands of said plastic net material has from about 10 to about 20 strands per 10 inches.
Claim 9
Dependent Claim
176 words
A palletized load comprising a pallet device and a plurality of containers on said pallet device, said pallet device and said containers being unitized with a pallet wrap, said pallet wrap being a plastic net material selected from the group consisting of polypropylene and high density polyethylene, the plastic net material comprising two sets of strands, one set of which is in the longitudinal direction of the net and the strands of said one set being essentially parallel, the other said set of strands being transverse to the one said set of strands, said one set of strands being stretch-oriented to a sufficient degree so that it is incapable of being stretched further by more than about 15% in said stretch-oriented direction when stressed under the tension to which normal palletized loads are subjected at temperatures up to about 180° F., each said set of strands having from about 10 to about 20 strands per 10 inches, the weight of the plastic net material being from about 2.0 to about 3.5 pounds per thousand square feet.
Claim 10
Dependent Claim
176 words
A palletized load comprising a pallet device and a plurality of containers on said pallet device, said pallet device and said containers being unitized with a pallet wrap, said pallet wrap being a plastic net material selected from the group consisting of polypropylene and high density polyethylene, the plastic net material comprising two sets of strands, one set of which is in the longitudinal direction of the net and the strands of said one set being essentially parallel, the other said set of strands being transverse to the one said set of strands, said one set of strands being stretch-oriented to a sufficient degree so that it is incapable of being stretched further by more than about 15% in said stretch-oriented direction when stressed under the tension to which normal palletized loads are subjected at temperatures up to about 180° F., each said set of strands having from about 10 to about 20 strands per 10 inches, the weight of the plastic net material being from about 2.0 to about 3.5 pounds per thousand square feet.
Claim 11
Dependent Claim
92 words
In the process of tension wrapping palletized loads with a plastic net material, the improvement comprising said plastic net material comprising a plurality of sets of spaced strands, the strands of at least one set being substantially parallel and being in the longitudinal direction of the net, said one set of strands being stretch-oriented to a sufficient degree so that it is incapable of being stretched further by more than about 15% when subjected to a tension within 20% of the tension required to break the strands of the said one set.
Claim 12
Dependent Claim
92 words
In the process of tension wrapping palletized loads with a plastic net material, the improvement comprising said plastic net material comprising a plurality of sets of spaced strands, the strands of at least one set being substantially parallel and being in the longitudinal direction of the net, said one set of strands being stretch-oriented to a sufficient degree so that it is incapable of being stretched further by more than about 15% when subjected to a tension within 20% of the tension required to break the strands of the said one set.
Claim 13
Dependent Claim
22 words
The process of claim 9 wherein said one set of strands is incapable of being stretched further by more than about 10%.
Claim 14
Dependent Claim
22 words
The process of claim 9 wherein said one set of strands is incapable of being stretched further by more than about 5%.
Claim 15
Dependent Claim
52 words
The process of claim 9 wherein said plastic netting material is polypropylene, has about 10 to 20 strands per 10 inches of longitudinal strands and about 2 to 6 strands per 10 inches in a direction transverse to the longitudinal direction and weighs about 3 to 7 pounds per thousand square feet.
