The corrugated boxes are like connected arched doors, which are parallel to each other in a row, supporting each other to form a triangular structure, which has good mechanical strength, can also withstand a certain pressure from the plane, and is rich in elasticity and good buffering.
1,According to the cross-sectional flute type, it can be divided into: V-type, U-type, UV type
(1)The radius of the V-shaped corrugated arc is very small, and the corrugated shape formed is like a triangle, and the compressive strength is high with the help of the combined force of the two oblique lines. However, if the applied load exceeds its bearing limit, the flute shape will be destroyed rapidly, and the load cannot be restored to its original state after the load is removed, that is, the elasticity is poor.
(2)The U-shaped corrugated arc radius is larger, so the elasticity is better, and the elastic deformation occurs within a certain limit after loading, and the external load is eliminated, and the original state can be basically restored. U-shaped corrugated due to the arc-shaped stress point, not stable enough, so the compressive strength is low, its arc and the bottom of the surface contact surface is larger, the amount of adhesive is large.
(3)UV corrugated combines the advantages of the above two flutes, and has high compressive strength and elasticity, and also has a relatively reasonable amount of raw materials, so it is widely used at present.
