Classified uses of corrugated boxes

What are the classifications of corrugated boxes produced by corrugated box manufacturers, and what are their uses?
Corrugated box is currently a packaging container widely used in transportation packaging, which is made of corrugated cardboard material. Corrugated board is made by bonding facial paper, lining paper, core paper and corrugated paper processed into corrugated paper. According to the needs of commodity packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer and other corrugated cardboard.
The function of corrugated cardboard bonded into different corrugated types is also different. Even if the same quality of facial paper and lining paper are used, the performance of the corrugated cardboard formed by the difference in the shape of the corrugated paper is also different. At present, the internationally common corrugated types are divided into four types, which are A-flute, C-flute, B-flute and E-flute.
A-type flute is the highest, the corrugated cardboard made has better cushioning, rich in elasticity, suitable for packaging lighter products, C-type flute is second to A-type flute, but stiffness and impact resistance are better than A-flute; B-type flute arrangement density is large, the corrugated cardboard made of flat surface and high bearing pressure, suitable for packaging heavier and harder items; E-flute is thin and dense, which shows its rigidity.
