Corrugated type, especially corrugated board type, there are four types of conventional corrugated: A Leng, B Leng, C Leng, E leng.

Characteristic

A: flexibility, height and spacing, good shock absorption, suitable for fragile and impact and collision requirements of high products;

B: suitable for making products that are rigid and do not require shock absorption and protection, such as canned food, small packaged food, hardware, etc.;

C Leng: AB features two kinds of bow, which has enough rigidity and shock absorption performance;

E Leng: can be carton surface smooth, rigid better, suitable for high quality printing, and save transportation, storage space.

Corrugated paper is structurally characterized by corrugated corrugated. Corrugated is the main body of corrugated paperboard. Corrugated paper is made of the same texture and core paper, and the corrugated paperboard has different properties if the shape of the corrugated is different.

Nowadays, corrugated cardboard used in various countries in the world has the following types:

A type Leng B type Leng C type Leng E shape.

Its use can be summarized as follows:

For outer packing -- A, B and C

For internal packing -- B, E

Small package -- E shape

种类	楞率	楞数	楞高
A 楞	1.49	34±2	4.5-4.8
B 楞	1.31	46±2	2.5-2.8
C 楞	1.41	39±2	3.5-3.8
E 楞		93±5	1.0

　Next, let's talk about the features of A, B, C and E for outer packing.

1) A type arris

Type A is characterized by a small amount of corrugated per unit length, while corrugated is the highest. Corrugated boxes made of A - shaped roll are suitable for lighter packing and have greater cushioning force.

2) B type arris

B type and A type corrugated corrugated opposite number in the unit length of the corrugated corrugated and its performance is the lowest, and A type corrugated corrugated type B is used instead, made of corrugated box for packaging heavy and hard goods, used for canned and bottled goods packaging.

In addition, there is a tendency to make use of B type hard and hard to break the characteristics of, after punching cut into a complex shape of the combination box.

3) C type arris

The corrugated number per unit length and the roll height of C - shaped roll are between the A - shaped and B - shaped ribs. The performance is close to that of A type. In recent years, with the increase of storage and transportation costs, the smaller size of C shaped beam has been paid attention to, and has become the European and American countries.

4) E type arris

E 30 cm in length in the Leng Leng number is generally about 95, about 1.1 mm high Leng, compared with the packaging used in A, B, C type corrugated, with thinner features more hard. Therefore, the main purpose of developing E shaped frames is to fold them into cartons to increase cushioning. The corrugated paper box made of E corrugated board has beautiful appearance, smooth surface and complicated printing, so it is usually used in decorative corrugated cartons.

瓦楞种类	A 楞	B 楞	C 楞
平面压力	3	1	2
垂直压力	1	3	2
平行压力	3	1	2
缓冲压力	1	3	2

　At present, we mainly use B, A, E, AB and BE.

Two, corrugated cardboard types

The type of corrugated board depends on the combination of various types of corrugated. Combination of different ways, corrugated cardboard physical properties are also different.

Usually corrugated cardboard can be classified according to its structure or use.

Single-sided corrugated board

Double sided corrugated board (three layers single wall corrugated paperboard)

According to the structure classification, double core double sided corrugated paperboard (five layers double corrugated paperboard)

Three core double sided corrugated paperboard (seven layers, three corrugated cardboard)

Inner packing corrugated paperboard

Classification by use

Corrugated cardboard

According to the structure classification, the same way classification is based on the use of several paper and tissues of Zhang xin.

Three. Brief introduction of box type

Corrugated box structure, in the world generally used by the European corrugated box manufacturers association (FEFCO) and the Swiss cardboard Association (ASSCO) jointly formulated international carton box standards. This standard, approved by the International Corrugated Board Association, is internationally common.

According to the international carton box standard, carton structure can be divided into two types: base type and combination type.

The basic type, that is, the basic box type, in the standard legend can be found, generally with four digit representation, the first two indicate box type, and the latter two indicate the same carton type of different carton style. For example: 02 means slotting type carton; 03 means sleeve carton and so on. The combination type is a base type combination, which consists of more than two basic box types, and is represented by more than four groups of digits or codes. For example, the top roll of a carton can be of type 0204, and the lower cover shall be of type 0215.

1:A type carton: it is made of a whole piece of cardboard. After cutting and grooving, the box is formed and has a folding plate, which can be used to separate the two boxes of the carton relative to each other

1, commonly used slot type (A1), RSC0201 type

2 overlap slot box 0202

3 、 central special slit box 0204

4 、 central special overlap slot box 0205

5, full overlap slot box 0203

6 、 central special overlap slot box 0206

The 2:C type carton is made of two or more corrugated cardboard boxes, which is characterized in that the case is provided with a case with a cover and a bottom cover

1 、 lid type structure box

A partially assembled structural box (box cover with a depth of 2/3)

B fully assembled box (0301) (box top is worn at a height of box)

C double cover box (0310): box and top, cover three boxes of box shaped box

D have lid structure box (0306): two piece box board form, box cover depth is box

Body 2/3

E lock type double lid box (0325): the top cover and the bottom cover are cut into flanges for the purpose of

The flanges of the case are locked together with each other

2 、 lid type slit box

A full set of half slotted box (0320)

B partial sleeve half slit box

C covered semi slotted box (0312)

D three piece double box

The 3:D type carton carton system is composed of a box body and two end plates.

1 and second vertical boxes (0605)

2 and fourth cases (0601)

4: other types of carton

1, double sliding box (0510)

2 folding box (0401)

Note: wrap the corrugated carton (i.e. automatic packing carton) and some similar type 0210 cases, the difference between the two: 0210 box to box blank cardboard corrugated parallel to the width, and the wrap of corrugated cardboard to parallel to the long; 0210 cases of joint in the main box, and wrap carton is connected on one side of the case; 0210 cases of internal and external cover indentation in a straight line, and wrap box is different. In addition, compared with the standard box, the package type carton is characterized by less material, cartons and internal materials closely affixed, you can achieve high-speed automation.

Corrugated box of a wide variety, according to its structure, can be divided into three broad categories:

(a) slotted cartons (type 02);

(b) jacketed cartons (type 03);

(c) folding carton (type 04);

The slotted carton (type 02)

The slotting carton is the most basic packing type in the transportation package, and it is also the most widely used carton. It is made of one or more pieces of processed corrugated cardboard, made of nails or bonded together. The bottom and the top flap (its upper and lower cover) a box bottom and a box cover.

Of which: A1 type for shake lid, the outer cover anastomosis, the inner cover is not connected.

This kind of carton can be folded and laid flat during transportation and storage. It has the advantages of small size, convenient operation, sealed dust proof, clean inside and outside, etc..

Jacketed carton (type 03)

The utility model is composed of a piece or pieces of processed corrugated cardboard, and is characterized in that the box body and the box cover are separated, and the sleeves are assembled when used.

The advantages of this kind of cartons are packing and sealing. It is not easy to fall off after the goods are loaded. The whole strength of the carton is higher than that of the slotted carton. The disadvantage is that it is large in size and inconvenient to transport and store.

Folding carton (type 04)

Folding carton, also called special-shaped carton, usually consists of one piece of corrugated cardboard, which forms the low, side and box lid of carton without folding and bonding.

The corrugated box accessories

In order to avoid damage in the process of transportation, according to the characteristics and requirements of different commodities, it is necessary to design a reasonable structure of the accessories, play a role in the protection of goods. The basic carton accessories are made up of the following:

A separator: for bottles of fragile and fragile objects packaging, each item is separated in the box, to prevent shaking, collision.
