Abstract
Abstract A pallet load of product is secured onto a pallet by enclosing the load including the top thereof in thermoplastic film which is heat shrunk to the load, to a sheet of thermoplastic film on the pallet under the load, and to the edge of the pallet therearound. The load enclosing film may be an inverted bag which covers the top and side of the load and the lower end of the bag is fused to said sheet which is on the pallet under the load. Alternatively, the side of the load may be covered by a sleeve of thermoplastic material and the top of the load may be covered by a separate sheet to which the sleeve is fused. Also, layers of thermoplastic sheet material may be disposed between layers of the pallet load and heat sealed to the sleeve which surrounds the pallet load.

Claim 1
Independent Claim
80 words
A pallet load, comprising a pallet, a load carried by said pallet, a layer of heat-sealable thermoplastic film covering the top of the load, a sleeve of heat sealable thermoplastic film surrounding the load and the pallet and heat sealed to said layer and heat-shrunk around the load, and the pallet, and a second layer of heat sealable thermoplastic film covers the top of the pallet and is heat sealed to the sleeve around the lower part of the load.
Claim 2
Dependent Claim
80 words
A pallet load, comprising a pallet, a load carried by said pallet, a layer of heat-sealable thermoplastic film covering the top of the load, a sleeve of heat sealable thermoplastic film surrounding the load and the pallet and heat sealed to said layer and heat-shrunk around the load, and the pallet, and a second layer of heat sealable thermoplastic film covers the top of the pallet and is heat sealed to the sleeve around the lower part of the load.
Claim 3
Dependent Claim
79 words
A pallet load, comprising a pallet, a load carried by said pallet, a layer of heat-sealable thermoplastic film covering the top of the load, a sleeve of heat-sealable thermoplastic film surrounding the load and the pallet and heat sealed to said layer and heat-shrunk around the load and the pallet said load being arranged in a plurality of discrete layers vertically of the load, and a layer of heat-sealable thermoplastic material being disposed between said layers of the load.
Claim 4
Dependent Claim
79 words
A pallet load, comprising a pallet, a load carried by said pallet, a layer of heat-sealable thermoplastic film covering the top of the load, a sleeve of heat-sealable thermoplastic film surrounding the load and the pallet and heat sealed to said layer and heat-shrunk around the load and the pallet said load being arranged in a plurality of discrete layers vertically of the load, and a layer of heat-sealable thermoplastic material being disposed between said layers of the load.
Claim 5
Dependent Claim
71 words
A pallet load according to claim 1, further characterized in that the second layer of heat-sealable thermoplastic film covers the top of the pallet and is heat sealed to the sleeve around the lower part of the load, in that said load is arranged in a plurality of discrete layers vertically of the load, and in that a layer of heat-sealable thermoplastic material is disposed between said layers of the load.
Claim 6
Dependent Claim
