Also called American box, the folding box is a packaging of four side faces (mathematically a prism base rectangular) that closes both its top and bottom by four flaps. Usually made of cardboard, its versatility and high resistance to stacking has become the most popular of the boxes. They are of different sizes, even large enough to allow a homeless or drunk person to sleep in it, or at least can improvise some kind of protection or roof.
Structure
Structurally, the cardboard box is a closed ring covered by four flaps taken from the structure itself. The flaps typically have a uniform to optimize the ironing surface height, long bend joining in the center of the case and short stay recessed below them. Its height is therefore equal to half the width of the packaging.
The wave is placed in the vertical direction to give the packing maximum strength. Therefore, usually it is located perpendicularly to the rim except in cases where the traveling box lying on it is designed in the opposite direction.
Manufacturing Process
The first step involves inserting the cardboard sheet of cloven by those who bend the top flaps. This is done in the manufacturing process of the plate itself in the corrugator through a circular die called slitter.
Then, as in the rest of cardboard packaging, the manufacture of the box begins decoration plate which is performed on a printer. Flexographic printing uses clichés of polymer to deposit the ink on the substrate, requiring many clichés as colors carry for the case. Usually, the printer is placed in line with the casemaker which is the machine that will give the final structure to the box. In this machine, the grooving is performed to form the flaps, split in the direction of wave, folding and gluing of the box attachment flange. Thus, the box is ready for further packaging. Finally, operations take place for palletizing and strapping.
Packaging Folding Box
The cardboard box is a versatile packaging line used in automatic manual packing much. In the first case, the process is as follows.
The bottom flaps are closed with sealing and the product is introduced and reconditioned manually and the top flaps are closed with another seal.
In the second case, the process is performed through packer machines that are installed at the end of the packaging line. There are various systems for American boxes encased but the basic procedure is as follows; The product units are grouped into batches according to the number to be packaged. A cupping forms the box and proceeds to the lower closed by hot melt glue and then the product is introduced therein.
