How Is The Corrugated Carton Made ?
Corrugated paper board is made of face paper, inner paper, core
paper and corrugated paper processed into corrugated corrugated
corrugated paper by bonding. According to the demand of commodity
packaging, corrugated board can be processed into single-sided
corrugated board, three-layer corrugated board, five-layer,
seven-layer and eleven-layer corrugated board.
Corrugated boards with different corrugated shapes have different
functions. Even if the face paper and the inner paper of the same
quality are used, the performance of corrugated board is different
due to the difference of corrugated shape. There are four types of
corrugated ridges commonly used in the world, which are A-type
ridges, C-type ridges, B-type ridges and E-type ridges. See table 1
for their technical indicators and requirements. Corrugated board
made of A-type corrugated board has better cushioning and
elasticity, while C-type corrugated board is better than A-type
Leng Ci. But stiffness and impact resistance are better than A-type
stare blankly. B-type corrugated board has high density, and the
surface of corrugated board is flat and high bearing pressure,
which is suitable for printing; E-shaped stare blankly is thin and
dense, which shows its rigidity and strength.
The difference between container and non-container mainly lies in
the outer diameter, which is closely related to the corrugated
type. The following table will detail the relationship among carton
inner diameter specification, manufacturing specification and outer
diameter specification:
Measuring method for manufacturing dimensions of corrugated boxes
The manufacturing size of carton is the blanking size when making
carton. The manufacturing dimension is based on the pressing line
on the unfolded box blank. The indentation roller on the slitting
machine presses a groove at the line pressing position, and the
line pressing is the center line of the groove. The distance
between two pressing lines is the manufacturing dimension.
Conversion of manufacturing dimensions into inner and outer
diameter dimensions can be achieved quickly by Table 2, but they
also have their own measurement methods.
Corrugated boxes can be divided into single and double spelling in
the manufacturing process.
Single spelling is a one-page forming box, which is generally used
for cartons with small circumference; Double-box is also called
two-page box. Some cartons are too big in circumference, so they
have to be pieced together with two blanks. However, sometimes, in
order to make use of the surplus materials cut in the production
process, carton factories will also use two pieces to piece
together a carton which is not too big in size, and sometimes even
use four pieces. Compared with the one-page box, the two-page box
has one more joint, so there are some slight differences in the
area calculation between them.
Joints and loops
The manufacturing dimensions of carton joints are determined
according to corrugated layers and production process level, which
are 35~40mm for single corrugated board, 45~50mm for double
corrugated board and 50mm for triple corrugated board.
When calculating the unfolded area of carton, the loss of loop must
be considered in the manufacturing process, and the size of loop is
determined according to the number of layers of paperboard, which
is generally 20 ~ 40 mm.
In order to facilitate the calculation in practical work, the rule
of adding "8" and "4" is uniformly adopted, that is, the sum of
joints and loops in the transverse direction is set to 8cm, and the
total sum of loops in the longitudinal direction is set to 4cm.
1. Calculation formula of flat box area
Through the above introduction, the area calculation of the flat
box can be expressed by the following two formulas:
The area of single carton is s = [(length+width) × 2+8] ×
(width+height +4)
The area of double carton is s = [(length+width+8) × 2] ×
(width+height +4)
[Note: The units of length, width, height, 8 and 4 are all in cm. 】
Expanded area of carton with upper full cover and lower socket.
Cartons with top full cover and bottom socket are generally small
in size, some of which are made of corrugated cardboard, and some
of which are produced only with single-layer coated white
cardboard, such as small outer packaging of medicines, foods and
cosmetics.
Cut length and tile height
In the manufacturing process of corrugated boxes, it is
particularly important to distinguish the concepts of cut length
and tile height. If you make a mistake, the strength of cartons
will be thousands of miles away, which will lead to the scrapping
of all produced cartons, resulting in huge losses.
Cut length refers to the length perpendicular to the corrugated
direction; Tile height refers to the length along the corrugated
direction.
Joints and loops
Here, the joint size is determined according to the number of
carton layers. The joint of three-layer box is generally 3cm, and
that of five-layer box is generally 4cm. The size of the loop is
calculated by 2cm.
2. Calculation formula for the area of carton with top cover and
bottom socket.
Cut length: L= (length+width) ×2+ joint+loop.
Height of tile: H=1/2 width+socket+height+width+wire return.
Area: s = l× h.
Note: Generally, the area of cartons is calculated with reference
to physical objects. After the cartons are 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 dimensions of joints and loops are
flexible according to different situations.
