According to different types of corrugated type, corrugating rollers can be divided into four types: A-type, B-type, C-type, and E-type. Corrugated type corrugated board produced with these four kinds of corrugating rollers is also called A-type corrugated type and B-type corrugated type. , C-type corrugated, E-type corrugated, because of the different types of concrete, its physical properties are also different, the scope of application is also different:
Type A corrugated: It is characterized by a small number of corrugations per unit length and the highest corrugation height. The carton made with A-type corrugated media has excellent shock-proof cushioning properties, and its vertical compressive strength is better than that of B-type, which is suitable for packaging lighter articles.
B-type corrugated: It is characterized by a large number of corrugated irons per unit length, and a low corrugated height. Its plane pressure resistance capacity exceeds A-type corrugation. Because B-type corrugated noodle paper and liner have more supporting points, they are not easily deformed, and the surface of corrugated cardboard is relatively flat, which can achieve good printing effect. It is suitable for packaging heavier and harder articles, and is often used for bottled articles. The packaging, in addition, can also use the B-type corrugated hard and not easily broken features, after punching and making a complex shape of the combination box.
C-type corrugated: The number of corrugations per unit length of C-type corrugated medium is between A-type corrugated and B-type corrugated. The shockproof performance is close to that of A-type corrugated, and the flat compressive strength is close to that of B-type corrugated. Small size packaging.
E-type corrugated: E-type corrugated is commonly known as fine corrugated, its corrugated height is about 1mm, and the number of corrugations per unit length is the largest. Compared with other types of corrugated files, it has the characteristics of thinner and harder. It can withstand a large plane pressure, its longitudinal compressive strength in the vertical and horizontal compressive strength is the same, made of corrugated box, beautiful cut, smooth surface, can replace cardboard for individual packaging and packaging.
In terms of pressure, type B bears the highest plane pressure and parallel pressure, and the vertical pressure is the worst; type A bears the highest vertical pressure, plane pressure and parallel pressure are the worst; type C bears between type A and type B. .
In actual production, it can be selected according to the respective characteristics and specific conditions of the four types of corrugated medium. Generally speaking, three-layer corrugated boxes are suitable for A-type and C-type, and five-layer corrugated boxes are suitable for A-type, B-type or B-type and C-type combinations. Close to the outer surface should be selected B-type, close to the inner layer. Should choose A type or C type. Medium-sized corrugated boxes are suitable for type B, and small-sized packages are suitable for type E.
