ABSTRACT:
A process and apparatus for packing a stack of loads with synthetic resin films each possessing heat contractility. A plurality of loads are stacked on a pair of synthetic resin films placed in crossed relationship on an elevating table. The elevating table is movable downward from its upper extreme position so that the synthetic resin films are continuously supplied to cover side peripheries of the loads. Adjacent rib portions formed by side edges of the synthetic resin films covering the side peripheries of the loads are joined during downward movement of the elevating table. Upper opposing portions of each of the synthetic resin films are bent toward each other and joined together on the upper surface of the stacked loads on the elevating table. The synthetic resin films covering the loads are heated so that the films shrink.
