Abstract: The apparatus is an impulse, radiant sealer for heat sealing thermoplastic films for packaging various goods. The apparatus includes means for supporting a flexible wire sealing element freely in space, under light spring tension, and for bringing the sealing element into contact with the films to be sealed, with the films being held flat at the seal area. The apparatus also includes means for heating the sealing element to a high temperature such that the thermoplastic films are sealed together very rapidly. Because of the high temperature of the sealing element and the high rate of speed with which the seal is made, the effect is such that the apparatus operates as a radiant sealer, and the seal has the appearance of having been made by radiant heat.

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.

Abstract: A pallet-load of product is secured onto a pallet by forming a sleeve of heat shrinkable film around the pallet-load with its open top extending above the pallet-load and its open bottom extending below the pallet. The bottom and the top portions of the sleeve are initially shrunk to lock the sleeve onto the pallet-load and the pallet, and subsequently the intermediate portion of the sleeve is shrunk to unitize the assembly.
