How to calculate the quotation of packing box

We need a carton, and naturally we will see the length, width and height of the carton. How to describe the size of the carton? Here, according to the container and

The difference between non-containers mainly lies in the outer diameter, which is closely related to corrugated type. So first tell us whether the carton is inside diameter or outside diameter.

That is, what is the length * width * height? How to calculate the carton area in our general production process?

1, the formula for calculating the area of docking box.

Through the above introduction, the area calculation of flat box can be expressed by the following two formulas:

Single-sided carton area s = [(length+width) × 2+8 ]× (width+height +4)

Double-sided carton area s = [(length+width +8) × 2 ]× (width+height +4)

Note: The units of length, width, height, 8 and 4 are centimeters.

Development Zone of Upper Full Cover and Lower Socket Carton

Cartons with full cover at the top and sockets at the bottom are generally small, some are corrugated cardboard, and some are white cardboard with only a single coating.

Such as medicine, food, cosmetics packaging.

Cutting length and tile height

In the process of making corrugated boxes, it is particularly important to distinguish the concepts of cutting length and tile height. One mistake, the strength of the carton is a thousand miles away.

In this way, the cartons produced will be scrapped, causing huge losses.

Cutting length refers to the length perpendicular to the corrugation direction; Tile height refers to the length along the corrugated direction.

Joints and rings

The size of the joint here is determined according to the number of layers of the carton. The joint of the three-layer box is generally 3cm, and that of the five-layer box is generally 4cm. The size of silk

Press 2cm uniformly.

2. Calculation formula of carton area with full cover and socket under it

Cutting length: L= (length+width) × 2+ connector+filament.

Tiling height: H= 1/2 width+socket+height+width+rewinding.

Area S= L × H

Generally, the area of cartons is calculated with reference to physical objects. After the carton is unfolded, the specific dimensions are analyzed according to the specific shapes of different cartons.

The length, width and height are all fixed by accurate measurement, and the size of the joint and coil is flexible according to different situations.

After calculating the unfolded area of the carton, use unfolded area * paper price per square meter+knife board+printing fee+process price.

Then divide by the quantity, which is the unit price of the carton.
