how to make one corrugated carton box
The first step is to purchase base paper and corrugated paper.
Combine the base paper and corrugated paper with a machine to make cardboard. Some factories have strong production capacity, and they can also directly purchase wood to produce their own base paper, which is a large kraft paper roll. The general carton factory is to purchase cardboard boxes made directly from outside, and the second-level carton factory processes the cardboard by itself to save costs.
The second step is to make cardboard as required.
Corrugated paper is divided into three types: A, B, C, and corrugated paper. The corrugated paper refers to a house like wavy paper sandwiched between kraft paper. At the same time, the carton is divided into three layers and five layers, three layers means there is a layer of corrugated paper, and five layers means there are two layers of corrugated paper.
The third step is to calculate the area and price.
Let's take an ordinary carton as an example. As long as you know the length, width and height of the carton, you can calculate the area. However, when calculating the total length, you need to calculate an extra part of the glue that is 2-3 cm. Internal company requirements. [(Length + Width) * 2 + 30] * Height * Price per square. The high refers to the overall height of the carton, including the height of the top and bottom swing cover. This figure is the selling price.
The fourth step is to make a rubber template based on the drawings and drawings.
The carton generally has printing requirements, so it must be attached to the paper, and the color and customer requirements should be indicated on the drawing. Then the printing room staff will make the rubber version as required. Generally ink-and-water printing is relatively simple, and the fonts and colors are not as complicated as offset printing. This rubber version is very important and is a must for printing.
The fifth step is to prepare the ink and debug the machine, and print on the machine.
Put the template on the machine, confirm the size of the length and width, first print a few to see the effect, one is to see whether the size is correct, and the other is to see whether the printing effect is satisfactory.
In the sixth step, the carton is formed.
That is, the carton is glued or nailed by the worker, and the carton is formed. The reason why the extra 2-3 cm is reserved is the key to carton molding. If it is glued, it can't be too big or too little when it is glued. If it is too much, it will easily stick to the surface of other cartons. If it is less, it will not stick.
The seventh step is packaging.
After the carton is formed, according to the size of the carton, pack it with 5 or 10 bundles with packing tape and set aside. Now there are automatic or semi-automatic packers for packing, which can be said to be simple and convenient.
