Corrugated board structure and carton thereof

Abstract

The invention discloses a corrugated board structure and a carton thereof. The corrugated board is composed of two layers of composite board layers and a honeycomb paperboard layer located between thetwo composite boards; and the composite board layers are composed of fireproof coating, waterproof board layers, drying agent filling layers and corrugated board layers which are arranged in sequencefrom outside to inside; the outer parts of the corrugated board layers and the surface of the honeycomb paperboard layer are mutually clamped through ridge-shaped corrugated paper in a fitting mode.According to the structure and the carton, the corrugated board structure is formed by bonding two layers of composite board layers and the honeycomb paperboard layer in the middle, the composite board layers are provided with the waterproof layer, the fireproof layer and the drying agent filling layer, so that the corrugated board is endowed with the moisture-proof and fireproof functions; and the corrugated board layers and the surface of the honeycomb paperboard layer are mutually clamped through ridge-shaped corrugated paper in the fitting mode, so that the mutual fixation in a transverseupwards mode is realized, then the honeycomb paperboard layer is inserted through chamfered edges, the connection of the composite boards and the honeycomb paperboard layer in the longitudinal direction can be enhanced, so that the corrugated board structure is stable, and not easy to deform.

Description

technical field [0001] The invention relates to a corrugated cardboard structure and its carton, belonging to the field of packaging materials. Background technique [0002] With the continuous development of the logistics industry, the demand for packaging boxes is increasing day by day. Most of the existing packaging boxes are surrounded by corrugated cardboard. Corrugated cardboard is made of at least one layer of corrugated paper and a layer of cardboard (also called cardboard), which has good elasticity and extensibility. [0003] The corrugated corrugated corrugated cardboard is like connected arched doors, which are arranged in a row with each other and support each other to form a triangular structure, which has good mechanical strength, can withstand certain pressure from the plane, and is full of elasticity and cushioning. Good effect; it can be made into liners or containers of various shapes and sizes according to needs, which is simpler and faster than plastic...

Problems solved by technology

[0003] The corrugated corrugated corrugated cardboard is like connected arched doors, which are arranged in a row with each other and support each other to form a triangular structure, which has good mechanical strength, can withstand certain pressure from the plane, and is full of elasticity and cushioning. Good effect; it can be made into liners or containers of various shapes and sizes according to needs, which is simpler and faster than plastic cushioning materials; it is less affected by temperature, has good shading performance, does not deteriorate under light, and is generally less affected by humidity. But it is not suitable for long-term use in an environment with high humidity, which will affect its strength

[0004] In addition, the opening of the box body of the existing packaging box is usually glued with adhesive tape between two pieces of corrugated cardboard. Once the items in the box are too heavy or the volume is too large, the opening at the bottom of the box body is easy to open, affecting transportation.
