The basic principles of carton packaging structural design

1. Elements

The structure of the packaging container is the combination with point, line, surface, body. For folding cartons, glued trays and corrugated boxes, the angle is a very important structural elements besides the elements mentioned above.

(1) Point

There are 3 types of structural point on the basic structural shape of carton packaging: the multi-faceted point of intersection, 2 sides point of intersection and points in the plane.

(2)Line

The crease line of the paper packaging can be divided into two categories according to the adaptation of automated machinery production: pre-folding line and working line.

(3) Surface

For the reasons of flat sheet forming the tray (box) surface can only be flat or curved surfaces.

(4) Body

From the way of paper packaging molding, the basic shape of the structure can be divided into the following three categories:

① Rotational molding Through rotating from the plane to three-dimensional shape, tube, tray, tube tray carton belongs to this kind of carton.

② Shift molding Through shifting the two parts of the carton body for a certain distance from two-dimensional to three-dimensional molding, non-tube non- tray belongs to this kind of carton.

③ Straight-reverse modeling Forming through straight-reverse the body of the paper packaging partitions, back cover, fixed structure.

(5) Angle

It is the key of paper packaging rotate modeling by point, line, surface and other elements compares to other kind of packaging materials.

2. carton packaging molding

There are 3 kinds of carton packaging molding methods: rotating, shifting, straight and reverse modeling. Each of them has their own advantages.

3*3 principles in carton packaging design

1. Three principles of the overall design

(1) the overall design should meet the habit consumers decide to buy the first observation of the carton packaging design surface (ie, including the main pattern, trademark, brand, manufacturer name, and sign the award-winning exhibition surface); or to meet the distributors' habit to window display, shelf display and other promotional activities so that it gives consumer the strongest visual impact face to face.

(2) the overall design should meet the habit of consumers in the observation or get the contents from front to back to open the lid.

(3) the overall design should satisfy the habits of most consumers with the right hand to open the lid.

2. Three principles of the structural design

(1) folding cartons connector should be connected in the second half of the board, in exceptional circumstances it can be connected to the end plate can be bonded with the rear panel. Unless a last resort, generally do not connect the front plate or end plate bonded with the front panel.

(2) The carton cover should be attached to the rear panel (except adhesive sealing cover and window style cover plate).

(3) The end panal should generally be connected to the front panel. Thus, when consumers face carton packaging, is not observed due to joints caused by the appearance of defects or from back to front to open the lid and bring inconvenience to take the contents.

3. Three principles of the graphic design

(1) The main graphic design of carton packaging should be designed in the tray front panel (tube box) or on the cover (tray box), text and secondary pattern design after the end plate or board.

(2) When the carton packaging need to be displayed vertically, the graphic design of the surface should be considered the position from the cover plate to bottom plate.

(3) When the carton packaging need to be displayed horizontally, the graphic design of the surface should take into account the habits of consumers with the right hand to open the packaging, the overall graphic design from the upper left to the right end, the open position at the right end.
