Corrugated box is a common and widely used packaging products, it has penetrated into all aspects of our daily life。Because of its extremely wide range of applications, its usage has always been in the forefront of various packaging products。It can be seen that the public loves it, since it is so popular with the public, let's take a look at what categories he has!

First, classification according to the number of layers

The composition of corrugated cardboard consists of four parts, including face paper, core paper, inner paper and corrugated paper with a processed shape showing a waveform, which is made of these four parts by bonding。

Different product types for packaging needs are also different, and the number of layers of corrugated cardboard can be made into a variety of types, it can be processed into single-sided corrugated cardboard, can also be processed into three layers of corrugated cardboard, in addition, there are five layers, seven layers, eleven layers of corrugated cardboard for people to choose。Of course, the more layers the corresponding quality will naturally be better。

Second, according to the corrugated shape of the classification

Corrugated boxes not only have different layers, it can also be made into different shapes, and the function of different shapes bonded into corrugated cardboard is also different。Even if the same quality of face paper and paper, but due to the difference in corrugated shape, the performance of the corrugated board is also very different。There are four types of corrugated shapes commonly used in the world, including A-type, B-type, C-type and E-type。

What are the different places of corrugated cardboard？Corrugated cardboard made of A-shaped corrugated has A good cushioning effect, better cushioning performance, and with some elasticity。In contrast, the C-type is second to the A-type in this respect, but the stiffness and impact resistance of the C-type are better than that of the A-type。The arrangement density of the B-type corrugated board is larger, and the surface of the corrugated board made of the B-type corrugated board is more flat, and the pressure is higher, and it is more suitable for printing。* The arrangement characteristics of the post-E type are thin and dense, which directly leads to its higher strength characteristics。
