Packaging Box Structure Design

Writing for this blog for so long, and i was always trying to surprise every one came into my blog. In a fact i was always surprised by the others’ blogs. They are so good and amazing. But i still try to do my blogs, because I believe I can some sort of help, maybe  a little, but this can be helpful for some new beginners for designing.

I am not a professional at design, and i do not know much software. And the only software for me that i mastered is Packmage. Not because i do not want to learn, in fact i am learning Flash, PS, CorelDraw, when i am free. I find that mastering a software is amazing, mastering more will be more fun and wonderful.

Packaging design software for corrugated box and folding cartons is done now, now I am going to do more.

How to make a window and portable structure?

Window structure and portable structure of the box, left and right side each has a handle structure,, two lever handles are formed in the opposite direction. After folding and pressing, forming the handle structure. The window structure directly designed on the main body,the window can seal the transparent plastic ,like PE.

The box is mainly used in electronic toy products and food as gifts, or family use. In modern packaging, users often hope to see the packaging shape and appearance of the product first (not buy products before they can see). To make this design structure used more and more.

The purpose of the present invention is to make the most common simple box type use widely by adding window and portable structure.

Windowed on the main body, so that transparent plastic can be sealed on the molding box window. We can see the built-in objects, before buying can let consumers to see the inside product, to meet the curiosity of consumers the first time, especially the electronic toys, consumers pay more attention to its appearance.
Window open on the biggest main body, then the area of the window can be bigger, the user’s view is more clear. Common remote control toy planes and cars on the market are big volume, opening a window on the structure can maximize the use of the box space.

In general, this kind of folding carton includes main body face, side face, plug cover and shake up and down the wing, and so on. The invention increases the structure 2, lid and handle configuration for the folding, including the top and bottom plane. Under the first controller on the plane and the handle in the opposite direction from the folding clasp each other, upon the completion of the folding, jointly formed the handle directly in the opposite direction carrying structure.

As shown in figure, this structure is the most to the left of the graph structure with 2 D plane (the fourth side) on the hollow out since the generation of cellular structure. With traditional after add holes inside the lacing cellular structure is not the same, the cellular structure is composed of box type folded his, don’t need any ropes and additives, and reduces to a certain extent the box type process, speed up the working efficiency.

Do you know the sizes of a folding carton?

Folding carton has three different sizes:inner size, outer size and manufacture size.

Inner size refers to the internal volume size of the packing.It is an important data to measure the packing volume of filling quantity , and an important design data to calculate the carton or carton volume machine how to coordinate with the goods inside decorations or the inner packing .

Outer size refers to the volume size of packing.It is an important data to measure the    occupied space size of packing, is also an important design basis to calculate the carton or carton size how to cooperate with the outer packing or transportation warehousing tools (such as truck and freight cars, containers, pallets, etc.)

Manufacture size refers to the size of production, namely, the size of the annotation on structure design drawings. It is of great importance in manufacturing paper and die cutting plate, and is closely related to the inner size, the outer size,   the thickness of the cardboard and the paper structure.

Tube type folding carton

    Definition on modelling :

    Tube folding carton lid where it located is in the box surface , the smallest of the area  L< B <H cartons, such as toothpaste box,film cannister box, etc.

 

    Definition on  structure:

    Tube type folding carton refers to during the molding process,  the carton box body through a connector joint,  the lid or the bottom both need  box board or inner piece, those would have to be assembled by folding, lock, fixed or sealing the carton. This kind of carton compared to disc, pipe disc box and not tube not disc ,not only the shape characteristics, manufacturing technology is also different.
