The mechanical strength of Dalian Mingcheng Packaging Co., corrugated cardboard corrugated board adhesive body high: is a multilayer, which comprises at least one layer corrugated core paper sandwich (commonly known as the "pit" or "corrugated") and a layer of cardboard (commonly known as corrugated cardboard "Kraft card"). It has high mechanical strength, can withstand the handling process of the collision and falling. Corrugated carton's actual performance depends on three factors: the structure of the core paper and paperboard characteristics and carton itself. Corrugated cardboard as a connected arches, each in a row, support each other, form a triangular structure, has better mechanical strength, can withstand the pressure from the plane, and full of elasticity, the buffer effect is good; it can be prepared into various shapes and sizes or container liner, than plastic buffer material is simple, fast; affected little by temperature, shading is good, by the light of deterioration, generally affected by humidity is small, but not long-term use in a high humidity environment, this will affect its strength.
