The first chapter of corrugated cardboard, the carton manufacturing base knowledge
A, the characteristics of corrugated cardboard, cartons, advantages and USES
1, it is the commodity packaging transportation one of the main materials; Corrugated cardboard and corrugated carton production beginning
In the 19 th century, in the early twentieth century can develop rapidly. Corrugated carton light weight, and price
Cheap, can produce many kinds of large size, before the use storage space is small, and all kinds of printing
Design, so in manufactured goods in transportation packing used widely.
2, the structure characteristics: by a single or multiple wavy corrugated cardboard and flat paper, glue into:
3, performance characteristics: corrugated good compressive strength and earthquake resistance performance, can withstand the pressure,
The impact and vibration:
Four, six advantages:
4.1 compressive shock
4.2 suitable for printing
4.3 easy to forming
4.4 light in weight
4.5 beneficial to the environment
4.6 low cost (than other packaging material speaking)
5, cartons, four function
5.1 protection goods
5.2 convenient storage
5.3 in advertising
5.4 promote sales

Second, raw materials is introduced (identification)
1, paper degrees
1.1 base paper: namely production/manufacturing cardboard carton paper as the raw material of the, also called drum paper or artillery paper.
The range of the base paper, generally, the minimum for 850, the most was 1800, a total of 14 odd width,
Base paper production into cardboard are 14 paper degrees (along the lines of the direction of pit cardboard width), 29 ", and ",
35 ", and ", and "... 55 ".
1.2 special paper degrees:
There are 57 ", and ", 63 ", 66 ", 67 ", 70 ", 74 ", 78 ", 82 ", 87 ", 90 ",
94 ", 98 ", etc. Kind of paper degrees.
1.3 the written form:
Usually said the size of the board, paper degrees in front of the writing, the length of the cardboard later.
Such as 31 "* 84", and "* 72"
2, the identification of the paper
2 1 of paper classification (gram weight and code)
K paper: 250 g/m2 T paper (white) : 200 g/m2
A paper: 175 g/m2 2 paper: 125 g/m2
B paper: 125 g/m2 3 paper: 105-115 g/m2
C paper: 127 g/m2 6 paper: 200 g/m2
G paper: 300 G/m2 7 paper: 260 G/m2
F paper: 112 g/m2 8 paper: 3 lOg/m2
W paper: 180 g/m2 9 paper (white) : 125 g/m2
KW (140 g/m2) and let the cattle white 1 paper: 112 g/m2
M paper: 160 g/m2 5 paper: 150 g/m2
2.2 based on the use of the classification
Noodles paper: namely corrugated cardboard top layer of the kraft paper, also called a corrugated board paper.
A. noodles paper (box board paper) is generally not the bleach kraft paper, kraft paper is to cork sulfate pulp
Mainly comprised of fiber, in long nets paper machine on manufacturing.
B. when not in paper in bleaching box at the top of the paper board add a layer of bleaching pulp, make the case for a white paper board
Color, one side of the box for primary colors pull paper called white flour box board paper (mottled white liner), appropriate
C. the ability of physical index is: quantitative (g/m2)
D. cardboard box of quantitative is commonly (127-310 g/m2), relatively carton is concerned.
The core corrugated paper: namely corrugated paper including the production of core corrugated paper (paper) and corrugated paper.
A. main chemical pulp by half (i.e. with virgin pulp sulfite and soda ash for the steam, garnish with mechanical grinding
Ground to a pulp) in long nets on paper machine made.
B. The main physical index for quantitative (g/m2).
C. corrugated paper 112-200 for quantitative general g/m2.
The paper: that is the most in a layer of corrugated cardboard, general use a paper with noodles paper also call box board paper.
Second, corrugated cardboard
L, the classification of corrugated cardboard
According to the layer of 1.1 points
Classification symbols representation method of reading standard notation
The single crater A3A single thick pit face A bottom A A175/112 / A175
Double pit A = A double thick pit face A bottom A A175/112/122/112 / A175
Three pit A = A three thick pit face A bottom A A175/112/112/112/112/112 / A175
Single saw A face the A3 pit slag coarse see pit A175/112
Double saw A face A3A3 pit of slag coarse double see pit A175/112 / A175/112
Single young pit A9 A face of slag young see pit A175/112
A9A9 face A double young pit of slag young double see pit A175/112 / A175/112
According to the classification of 1.2 sutra (GB6544-86)
Classification height (mm) commonly known as the pit number (a / 300 mm)
G pit 0.4 0.5 G pit
F pit 0.6-o. 7 F pit 125 and 2
A pit 4.5-5 A pit 34 and 2
B pit 2.5 3 B pit 50 and 2
C pit 3.5-4 C pit 38 and 2
D pit 1.7 2.7 D pit 78 and 2
E pit 1.1 2 E pit or young pit 96 and 2
Now on the market to increase the whole carton compressive, double pit board adopts A/B or to improve printing effect
Fruit double pit the cardboard E/B pit.
2. Watts Leng cardboard interpretation of the method
In order to reflect the corrugated cardboard and paper each (pit type) combination, use a code says,
Reading methods to remember two points:
2.1 in English letters or number represents paper:
2.2 3 and 9 with two number represents core paper and pit type, 3 said C pit or B pit, 9 said E pit.
2.3 each letter or a digital generally represent a layer of paper (face paper, corrugated paper, paper, in the bottom paper).
3. The structure of the board
With five layer board (double pit cardboard) as an example:
4. Of the corrugated cardboard stare blankly form
Corrugated stare blankly is the shape of the corrugated shape, a group of corrugated by two circular arc and connection of tangent.
Stare blankly form can be divided into V, U shape and uv form 3 kinds.
4.1 V: V the nets arc radius sutra, early pressure compressive performance is better, but more than the highest
Point it quickly destroyed. So the poor performance, resistance to pressure buffer strong, adhesive coating surface was small, no
Easy bonding.
4.2 U shape: U shape the circular arc of the larger half line sutra, rich play Chong, absorb the impact energy is bigger, and when
Pressure after eliminate can still be restored. So the good performance of the pressure, buffer weak, adhesives was coating
Face big, easy to bonding.
4.3 UV form: UV stare blankly between U shape stare blankly and V stare blankly, between the circular arc radius is greater than V,
Less than U shape, so both advantages, are widely used.
4.4 of the corrugated cardboard stare blankly form
Corrugated paper refers to the corrugated model types, namely the corrugated size, characteristics and our different classification. The same
Stare blankly type, its stare blankly type can be different, but the state GB6544-86 (corrugated cardboard) regulation all stare blankly
Type of stare blankly shape are UV form, stare blankly type usually have A, B, C, D, E four is relatively commonly used.
4.4.1 A stare blankly: A stare blankly characteristics is the unit length of corrugated number within little and corrugated the height of the great, A stare blankly
The cartons suitable for packing of the goods have more delicate cushioning force; Such as: broken out of glass cup, such as ceramic, etc.
4.4.2 B stare blankly: B stare blankly and A stare blankly instead, length of the mouth in the number of corrugated and corrugated highly small,
So B stare blankly carton packing suitable for heavier and the hard goods, more for canned beverages bottled items
Packing: in addition, because B stare blankly cardboard and not easy to destroy hard, can be used to manufacture complex shape of group
Close box.
4.4.3 C stare blankly: C stare blankly unit within the corrugated number and length of high sutra, between A and B type between,
Performance is close to A stare blankly, and cardboard thickness is less than A stare blankly, so can save storage and transport
Use, European and American countries used more C stare blankly.
4.4.4 E stare blankly: F stare blankly at length of corrugated number within the unit most, corrugated minimum height, with
Thickness smaller and more hard characteristics, and use it to the corrugated carton manufacturing folding cardboard buffer performance than normal
Good, and slotting incision beautiful, smooth surface, the color printing.
Four stare blankly type of use:
The outer packing-A, B and C stare blankly
The-B and E stare blankly
Small package-E stare blankly
Export packing products of corrugated cardboard stare blankly type (GB5034-85)
Sutra sutra type high (mm) stare blankly number (a / 300 mm)
A 4.5-5 34 and 2
C 3.5 4 40 soil 2
B 2.5-3 50 and 2
Five, cartons, with makings calculation (long, wide, high use to the dimensions are size)
1. General carton:
(wide + high + put several) * 2 (long + wide) + lap tongue
2. Ordinary double was box
(wide + high + put several) * (wide + long + lap tongue)
3. Half a wing by single box
(1/2 wide + + 1/2 put high number) * (2 + 2 + wide long lap tongue)
4. Half a wing double was box
(1/2 wide + + 1/2 put high number) * (wide + long + lap tongue)
5. The single wing by box
(2 wide + + put high number) * (2 + 2 + wide long lap tongue)
6. All the wing double was box
(2 wide + + put high number) * (wide + long + lap tongue)
7. Material box
Bei system actual size + left side a (10 a 12 mm)
Lap tongue: also called tongue slice and article nail, according to the commodity inspection standard "glue joint lap long tong, ue
30-40 mm, nail, lap long tongue 40 a 50 mm, to save costs, meet production conditions,
Now our company for joint general 30 mm, nailing $35 mm, industry standard single crater 1 1/4
Inch, 1 1/2 inch double pit, three pit l 3/4 inch.
Put several: also called into a mouth, in order to make up for a wave cover rocker, disappear cardboard thickness and the increase of the wave cover
