Corrugated box structure features and main classification

Corrugated paperboard mainly consists of two parallel flat paper sheets as the outer paper and the inner paper, sandwiching corrugated corrugated paper in the middle, and each paper sheet is made by adhering together the adhesive applied to the corrugated peaks.

According to the corrugation height and spacing, corrugated board is usually divided into corrugated boards of type A, B, C, E, F, G and so on. Among them, type A, B, and C corrugated cardboard are generally used for packaging. E, F, and G corrugated paperboards are currently used more and more widely. The number of corrugated sheets per unit length is larger and the corrugation height is smaller. It is thin and hard, and the corrugated folding paper box has better cushioning performance than ordinary paperboard. The slot has beautiful appearance and smooth surface. It can carry out more complicated color decoration printing, so it can well meet the eye-catching and eye-catching effect required by the merchants. Customers can find objects in many piles of objects, such as wine, soft drinks, pet food, etc. The packaging box thus also promotes what we call the use of fine corrugated cardboard.
