Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, in particular to a high-strength corrugated paperboard. Background Art

[0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and a layer of boxboard. It has good elasticity and extensibility and is mainly used to make cartons, carton sandwiches and other packaging materials for fragile goods. Corrugated cardboard is a multi-layer adhesive body, which consists of at least a layer of wavy core paper interlayer and a layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated boxes depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself. High-strength corrugated cardboard is a type of corrugated cardboard that is stronger than traditional corrugated cardboard.

[0003] Corrugated paper is widely used, and making corrugated cardboard is one of them. When the existing corrugated cardboard is used, the strength of the corrugated cardboard is low, so the corrugated cardboard is easily damaged during use, which may cause damage to the items loaded.
