The invention and application of corrugated paper has a history of more than 100 years. Because of its low cost, easy processing and high strength, corrugated packaging boxes are very common in our lives. As the trend of online shopping is becoming more and more obvious, the demand for corrugated packaging boxes is also increasing. In fact, corrugated packaging boxes can be used for product packaging in addition to transport packaging. Below, Xinpai mainly talks about the different types of corrugated paper commonly used in packaging, as well as the characteristics of different corrugated paper.


The invention and application of corrugated paper has a history of more than 100 years. Because of its low cost, easy processing and high strength, corrugated packaging boxes are very common in our lives. As the trend of online shopping is becoming more and more obvious, the demand for corrugated packaging boxes is also increasing. In fact, corrugated packaging boxes can be used for product packaging in addition to transport packaging. Below, Xinpai mainly talks about the different types of corrugated paper commonly used in packaging, as well as the characteristics of different corrugated paper.

There are four kinds of commonly used corrugated paper, namely A flute, B flute, C flute, and E flute.


A flutethe flute height (h/mm) is about 4.5-5.0, the flute width (t/mm) is 8.0-9.5, the number of flutes (pieces/300mm) is 34±3, and the board thickness is about 5mm. The compressive strength, elasticity and cushioning force are excellent, but it is also because the corrugated height is relatively high that it is easily damaged. It is generally used as a transport packaging material for lighter items.

 

B flutethe flute height (h/mm) is about 2.5-3.0, the flute width (t/mm) is 5.5-6.5, the number of flutes (pieces/300mm) is 50±4, and the board thickness is about 3mm. B-flute has high flat compressive strength and is suitable for packaging hard products, such as bottles, cans and other items. Most of the bottle and wine packaging boxes on the market use B-flute. At the same time, because the corrugated spacing is small, and the paper is relatively flat, the printing effect is very good.

C flutethe flute height (h/mm) is about 3.5-4.0, the flute width (t/mm) is 6.8-7.9, the number of flutes (pieces/300mm) is 41±3, and the board thickness is about 4mm. C flute combines the characteristics of A flute and B flute, and has sufficient rigidity and shock absorption performance. C flute used alone will be less,

 

E flute - flute height (h/mm) is about 1.1-2.0, flute width (t/mm) is 3.0-3.5, flute number (pieces/300mm) is 93±6, board thickness is about 1.6mm. Compared with the other three commonly used flute types, E flute is thinner and harder. The surface of E flute is very smooth and can be used for complex printing. Therefore, E flute is often used as a material for product packaging and gift packaging.


In fact, in addition to the above four commonly used corrugated types, there are heavy-duty corrugated (D corrugated, K corrugated) and micro-corrugated (F corrugated, G corrugated, N corrugated, O corrugated). Due to the high cost performance and high performance of heavy-duty corrugated products, heavy-duty corrugated is also replacing the market position of traditional wooden packaging. The purpose of micro-corrugated is to replace thick cardboard.
