2, the carton packaging structure classification
3, carton packaging structure design skills

First, the basic knowledge of the carton packaging
(1), the size of the carton
(2), all kinds of folding line style and function
(3), the international standard of small and medium-sized inverting lifted the lid cartons

The paper properties and the common varieties
White paper: also called white cardboard, its bottom, gray, white two kinds of surface points.
Board or straw board: also known as grass. Mainly used in the manufacture of all kinds of carton or carton, can also be processed into liner material.
Corrugated board paper: also known as ma board, it as panel glue, paper and corrugated paper core is made all kinds of structure of corrugated carton.
Corrugated board: due to shape of corrugated wave the name. It can be all kinds of carton and carton.
Plastic composite paper: composite is bond to each other by a variety of material, plastic composite paper is soft composite materials.

Carton structure – with this important element in the structure design
In the carton packaging, with this part is under load, stress, vibration, drop, and other factors affect the biggest part. In the structure design, need careful consideration.
Structure of the main points and box type structure and tray type two kinds.
With this structure design – box type structure:
Box type structure:
Refers to the carton box body and a box shaped, extension on surface of the box type box body four designed on the basis of different paper carton sealing structure in the form of bolted.
Box type structure can be divided into the following kinds:
1, the socket bottom sealing type:
2, glue sealing type:
3, End lock type:
4, automatic lock bottom type:
5, partition bottom sealing type:
6, folding back cover type:
7, press the back cover type:
8, the press fixed type:

Commonly used box structure
E display (figure 1, figure 2, figure 3, figure 4,)
Display box and can be called “POP” boxes, advertising for sexual display, can fully show the packing form again. The form: one kind is with cover, exhibition will cover opened, transportation and buildings can be folded; Another kind is not with cover, the outdoor display. It has played a display, promote the role of commodities and introduce yourself.

How to use step and repeat wisely?

Packmage CAD’s step and repeat function is smart and optimized, but if there are more than one box type involving, this smart function cannot be used at this moment.

Now there are two structures:


Here’s a tip. It is a big order by the same customer. If you only use a structure design (left or right) , it will waste a lot of paper at the time of the final printing, The utilization of paper is not as good as these two structures used together.

Although the smart step and repeat of Packmage CAD cannot implement multiple intelligent optimization, but it doesn’t matter, this can be done in array by manually.
First, using the tools in the toolbar图片2 to put the two structures together. Just need to turn over the right structure as a whole, then move in together, is OK.


Second, click on the array:input rows and columns of the arrays. Then input column space and row space.图片4

This can do 48.



How many will be stepped and repeated if we only use one structure design?

Only 42.
Obviously, the utilization rate of the paper improved by using two structure designs together.
