First, the type of corrugated cardboard


The core of corrugated board is corrugated, so the shape, type and combination of corrugated board have a great influence on the properties of corrugated board. Let's talk about the basic points of corrugated type.

1. Types of oysters

The structural features of corrugated paper are corrugated corrugations. Corrugated is the main body of corrugated paper. Corrugated paperboards are made from the same paper and paper with the same texture. Corrugated paperboards have different properties if they have different shapes.
Nowadays, there are several types of corrugated paper used in various countries of the world: Type A, Type B, Type C, Type E.


The use of these four types of enamel can be summarized as follows: For packaging - A, B, C type enamel inner packaging - B, E type enamel small packaging - E type enamel

First of all, talk about the characteristics of Type A, B, and C types used for packaging.

1) Type A

A-type rakes are characterized by a small number of watts per unit length and the highest wattage. Corrugated cartons made from A-type crucibles are suitable for packing lighter items and have a greater cushioning force.

2) Type B

Type B and Type A are the opposite of each other. The number of corrugations per unit length is large and the corrugation is the lowest. The performance is also opposite to that of A-type corrugated. Corrugated boxes made of Type B corrugated are suitable for packing heavier and harder items. Used for canning and bottled items, etc.

In addition, there is also a tendency to make use of the characteristics of the B-type crucible, which is hard to break, and punched out to make a complex-shaped combination box.

3) Type C

The number of corrugations per unit length and the height of the C-type crucible are between Type A and Type B crucibles. The performance is close to that of Type A. In recent years, with the increase of storage and transportation costs, the smaller C-type cassette has attracted people's attention, and it has now become the type adopted by European and American countries.

Second, talk about the characteristics of E-type corrugated boxes used for inner packaging and small packages.

4) Type E

The number of turns of the E-type crucible in the length of 30cm is generally about 95, and the height of the crucible is about 1.1mm (the wavy height of our company E is 1.7mm). Compared with the A, B, and C-type varnishes used for outer packaging, the number of turns is more Thin and harder features. Therefore, the main purpose of the development of the E-type is to make it into a folding carton to increase the cushioning. Corrugated boxes made of E-type crucibles have a beautiful appearance and a smooth surface and can perform more complicated printing. Therefore, they are usually used for decorating corrugated boxes.

The above four types are shown below. Chart Corrugated Type Corrugation Height (mm) 30cm Standard Number of A Types 4.5-4.8 34±2
Type B 2.5-2.8 50±2
Type C 3.5-3.8 40±2
E type about 1.193±5
