Abstract: |
In order to improve on the compressive loading capability and package cushioning properties of honeycomb paperboard, the novel structure of corrugated and honeycomb composite paperboard is put forward in this article. It consists of honeycomb paperboard and corrugated paperboard, the honeycomb paperboard is the fundamental structure, and the single-wall corrugated paperboard is adhered on the liner (or facing sheet) of honeycomb paperboard with thickness smaller than or equal to 20mm. The aim of this paper is to evaluate on strength properties of the novel structure of corrugated and honeycomb composite paperboard by a series of experimental studies, and analyze the flat crush resistance, edgewise crush resistance, bursting strength and puncture resistance between the novel structure of paperboard and honeycomb paperboard by comparison. The experimental results show as follows: (1) For the honeycomb paperboard with thickness 10mm, the flat crush resistance of corrugated and honeycomb composite paperboard all reduce, yet for the honeycomb paperboard with thickness 15mm or 20mm, the flat crush resistances corrugated and honeycomb composite paperboard all raise on the whole. (2) For the same thickness honeycomb paperboard, the edgewise crush resistance of corrugated and honeycomb composite paperboard obviously increases than the honeycomb paperboard, moreover the double-face corrugated-honeycomb composite paperboard is best. (3) For the same thickness honeycomb paperboard, the bursting strength and puncture resistance of corrugated and honeycomb composite paperboard obviously increases than the honeycomb paperboard. So, the corrugated and honeycomb composite paperboard holds excellent strength properties such as flat crush resistance, edgewise crush resistance, bursting strength and puncture resistance on the whole, and it possesses an attractive prospective in transportation packaging of goods. All research work provides basic data and instruction for the design and application of the novel structure of corrugated and honeycomb composite paperboard in protective packaging.
