Corrugated paper type refers to the type of corrugated paper, that is, the different classifications of corrugated size and characteristics. The same flute shape can have different flute types, but the national standard GB6544-86 (corrugated cardboard) stipulates that all flute shapes are UV-shaped, and there are generally four types of flute types: A, B, C, and E.
① A flute : A flute is characterized by a small number of corrugations per unit length and a large corrugation height. A corrugated cartons are suitable for packaging fragile items and have a large buffer force, such as glasses, ceramics, and the like.
②B flute : B flute is opposite to A flute. The number of corrugations per unit length is large and the corrugation height is small. Therefore, B flute cartons are suitable for packaging heavier and harder items, and are mostly used for packaging bottled items such as canned drinks. In addition, because B corrugated cardboard is hard and not easy to damage , it can be used to make combination boxes with complex shapes.
③C flute : The number of corrugations per unit length of C flute and the height of flute are between A and B types, and the performance is close to A flute, and the thickness of the cardboard is smaller than A flute, so it can save storage and transportation costs. European and American countries mostly use C flute. Leng.
④E flute : E flute has the largest number of corrugations per unit length, the smallest corrugated height, and has the characteristics of smaller thickness and firmer. The corrugated folding carton made with it has better cushioning performance than ordinary cardboard, and the slotted cut is beautiful and the surface is smooth. , can be printed in color .
