Date: 2020-08-04 Views: 68 views


Corrugated board is a multi-layer adhesive body, which is at least a layer of corrugated core paper interlayer (commonly known as "pit zhang", "corrugated paper", "corrugated paper", "corrugated paper", "corrugated base paper") and a layer of cardboard (also known as "box board paper", "box board").It has high mechanical strength and can withstand collisions and falls during handling.The actual performance of corrugated boxes depends on three factors: the characteristics of the core paper and board and the structure of the box itself.


 


PAPERLINK company is specialized in making kraft paper making machine with long fourdurinier net or cylinder mould ,Ordinary corrugated paper can be divided into three layers, the outside layer: test liner ;The middle layer: corrugated paper; The inside layer: Inner lining  The kraft paper is 90-250g/m*2.

The outside layer is often called test liner, It also can be divided into three layers:  the first layer is made by pure wooden pulp, it’s GSM takes 18-25 of all kraft paper's GSM. The second layer is made by Short fiber,  it’s GSM accounts 50-60 % for total GSM. The third layer is made by long fiber, It’s GSM accounts 25-35 % for total GSM.

Kraft paper

Corrugated board like a connection of arch doors, parallel to each other into a row, mutual support, forming a triangle structure, with good mechanical strength, from the plane can also bear a certain amount of pressure, and elastic, good buffer effect; It can be made into various shapes and sizes of gaskets or containers according to the needs, which is simpler and faster than plastic buffer materials. It is small under the influence of temperature, good shading, and does not deteriorate under the influence of light. Generally, it is also small under the influence of humidity. However, it is not suitable to be used in the environment with high humidity for a long time, which will affect its strength.
