ュリンク梱包方法に係る。Structure of the Invention Means for Solving the Problems The present invention has been made to solve the above-mentioned problems of the conventional art. A bag made of heat-shrinkable synthetic resin film is wrapped around the packaged item from above until the hem reaches near the bottom edge of the pallet, and the bag is heated with a heating device to bond the tape and film together. The present invention relates to a shrink-packing method for palletized objects to be packaged, which is characterized by thermally welding and shrinking the latter at the same time.

し得る。The method of the present invention is generally applied to provide sealing properties and rigidity to palletized loads for transportation or storage, and the objects to be packaged include bottles stacked in multiple tiers wrapped in outer cardboard. It can be applied to a wide range of products that can be stacked on a pallet, such as ordinary carton-packed products.

る。Function In the present invention, a synthetic resin tape is first wrapped around the pallet of the items to be packed, and then a bag made of heat-shrinkable synthetic resin film is placed over the pallet so that the hem of the film reaches near the bottom edge of the pallet. The hem of the film bag and the tape are heated and welded together, and at the same time the entire film bag is heat-shrinked.The hem of the film is tightly attached to the four circumferences of the pallet using the tape, which improves the sealability of the film and the integrity of the entire package. This ensures rigidity. According to the present invention, there is no need to lift the load during heat shrinkage, film unpacking, etc., and the amount of film used is greatly reduced.

Spread a cardboard sheet on the pallet of the table conveyor, line up the first tier of bottles on it, spread a cardboard sheet on top of this group of bottles, line up the second tier of bottles on top of it, and do the same. Bottles are stacked one after another, a cardboard sheet and a top frame are placed on top of the topmost bottles, and these multi-tiered bottles are placed around the four peripheries of the pallet 2 as items to be packed 1, as shown in the schematic diagram in Figure 1. thickness 0゜1m
A polypropylene tape 3 having a width of 50 m and a width of 50 a* was wound around the pallet 2, and then a polyethylene film bag 4 having a thickness of 75 microns was placed on the pallet 2 so as to overlap the tape 3 up to the vicinity of the lower end of the pallet 2. On the other hand, as shown in FIG.

はなく。The polypropylene tape 3 and the hem of the polyethylene film bag 4 are completely welded, and this part is completely adhered to the pallet, and the polyethylene bag 4 as a whole also shrinks well, so that the center of each side of the tape 3 As shown in FIG. 3, the portion 3a tends to curve upwardly into an arched shape due to the shrinkage of the polyethylene film, but this is not a problem.
梱包物は一体として十分な密封性と剛性を確保できた。The packaged product was able to ensure sufficient sealing performance and rigidity as a single unit.
