摘要
目的利用新型经纬线纸研制高强度冷冻防潮瓦楞纸箱,以适应冷链食品低温贮藏、运输的物流环境。方法实验测试经纬线纸包装特性,确定其适合瓦楞纸板的组分;应用Ansys分析软件,建立经纬线瓦楞纸箱和普通瓦楞纸箱的有限元模型,模拟实际流通环境对纸箱模型施加载荷,求出2种瓦楞纸箱的抗压强度;进行空箱抗压实验,比较2种方法下经纬线纸箱与普通纸箱的抗压强度大小。结果用预应力经纬线纸作为瓦楞纸箱的面纸,在低温流通环境中其空箱抗压强度比相同芯纸和里纸的普通瓦楞纸箱高约30%,并且经纬线纸纸箱的质量比普通瓦楞纸箱的质量低12%。结论在实际生产中,可以利用经纬线纸制造高强度的低温防潮箱,以适应冷链流通环境,也可以制作低克重高强度纸箱,以节约纸箱用纸量。
This experiment developed a novel high-strength and moisture-proof corrugated box for refrigeration to adapt to the logistics environment of low-temperature storage and transportation of cold-chain food. By testing the packaging features of the warp and weft paper, the composition of corrugated box was determined. The finite element models of the warp and weft corrugated box and the ordinary corrugated box were established by use of Ansys software to simulate the actual environmental load imposed on the models and calculate the compression strength. The compression strength test on empty box was also conducted to compare the compression strength of the two kinds of corrugated boxes.The results showed that in the logistics environment of low temperature, the compression strength of the box made by warp and weft paper was 30% higher than ordinary corrugated boxed and the weight of the warp and weft box was 12% lower. In practical production,the warp and weft paper can be used to make high-strength and moisture-proof corrugated box which is suitable for the cold-chain logistics environment. This kind of paper also can be used to make boxes of lower weight and higher strength, which can save paper usage.
