And a columnar tray aggregate to be packaged with, and a packaging film that pseudo-bonds (temporarily) adheres to the surface of the columnar tray aggregate to wrap the columnar tray aggregate in a non-shrinking state, and The packaging film is sealed at the edge along the stacking direction of the tray to form a tubular shape,
And a packaging bag having one or several perforations provided in a part thereof along the stacking direction of the tray, and a columnar tray assembly is applied to the outer peripheral surface of the tray in the packaging bag in a non-contracting state. It is housed in a pseudo (temporary) adhesive state with an adhesive or the like.

[Function] By applying the adhesive or the like applied to the outer peripheral surface of the tray to the packaging in an incompletely dried state, the molded trays are stacked to form a columnar shape, and the columnar tray aggregate is collectively adhered with the adhesive agent. Even after the adhesive or the like has been applied incompletely dried, it is possible to immediately proceed to the packaging work for shipping, and to completely dry the adhesive and the like applied to the outer peripheral surface of the tray after molding. A large drying room and storage space can be eliminated, and the efficiency of gluing and shipping work can be improved.

In addition, since the columnar tray assembly is housed in a pseudo (temporary) adhesive state with the adhesive or the like applied to the outer peripheral surface of the tray in the non-shrinkable packaging bag, a process such as heat shrinkage is not required, Each tray does not move loosely and is fixed as a column-shaped tray assembly, so the packaging film can be sealed at the edges along the tray stacking direction. Both ends may or may not be sealed, and the packing and sealing work can be simplified.

Then, when the tray is taken out from the packaging bag and used, one or several perforations provided along the stacking direction of the trays are used, and the banana is just peeled and wrapped. The film in the bag can be turned off, and the tray can be easily taken out even if the film does not slip on the tray.
